     FIELD OF THE INVENTION 
     The present invention relates to a methods and apparatus for converting natural gas with heavier hydrocarbon gas content at remote locations dynamically into a set of useful products including pipeline quality natural gas and blended gas products to power application units such as multi-fuel micro-turbines. It provides a method and apparatus for managing variable, multi-phase fluid conversion to output fuel and energy for providing customizable management for processing a volume of natural gas including a volume of methane and a volume of other alkanes that may be cleaned of the other alkanes using a conversion system to create gas and other fuel products to be used in onsite or combined heat and power or cogeneration applications. In particular, the method, system and apparatus provide for automated feedback and control directing various gas constituents to different application units with allocations according to settings system parameters to quickly and efficiently meet demand for various products while making adjustments in real time. 
     BACKGROUND 
     Generally, oil wells often have an amount of natural gas associated (also referred to herein as “associated gas” and “flare gas”) with them. Crude oil and natural gas are extracted from the oil wells together and the natural gas and crude oil must be separated. In remote areas with insufficient infrastructure or where the economics present a challenge, this associated gas may be flared. The flaring process causes carbon dioxide and volatile organic compound emissions and is being targeted for removal for environmental protection reasons. 
     Natural gas associated with oil wells can be high in alkanes other than methane (C1), such as ethane (C2), propane (C3) and butane (C4). These higher carbon number alkanes are of high caloric value and, in some embodiments, may allow for transport of the energy in the form of a highly dense liquid referred to as natural gas liquids (“NGLs”). Though these other alkanes are often used as fuel in other industries, technological limitations on their separation and handling with regard to associated gases unfortunately results in these constituent gases being wasted and often harmfully introduced into the greater environment. 
     Remote processing of natural gas to remove the “NGLs” or convert the entire stream to liquids has attracted great attention. The two leading processes in this industry are basic membrane separation and gas to liquid conversion (Joule-Thomson or cryogenic separation) with drier gas high in methane and a nonmethane stream. Both processes are energy intensive and typically require onsite electrical power generation. 
     Membrane separation pressurizes the stream to high pressures (1000+PSI) and forces the gas through membrane sieves which force the liquids to condense and allow the liquids to be removed. Membrane separation is unable typically to remove ethane because its size is relatively close to methane. The resulting natural gas from membrane separation is not of pipeline quality because of its ethane content. 
     These two technologies, however, are not well suited for removal and transport of natural gas streams at well sites. The technologies are very energy intensive and require onsite electrical power to be utilized. Oil well sites including remote oil well sites have electrical demands that currently are fed by expensive grid power , high emission inefficient natural gas generators and expensive local diesel generators. Where the gas extracted from the oil well is of a high enough quality, natural gas generators (“genset”) are used. Well sites prefer to use the gas from the nearby well because it is a byproduct of oil removal. Currently available and utilized natural gas generators require near pipeline quality natural gas in order to function optimally. Often, extracted natural gas is not of sufficient quality or are high in alkanes other than methane required by most power generating units available. Power generating units can only use fuel with specific heat values and cannot function outside of those ranges. Even newer turbines that accept a greater range of fuel with additional non-methane components still require essentially standard mixtures and cannot adapt well to time-varying composition of aggregate gases and must shut down if fuel gas exceeds specification limits. Most combined heat and power or cogeneration systems and components cannot operate efficiently on extracted associated gases, especially because there is great variation and fluctuation in the associated gas flow at any given point in time due to natural occurring factors and issues including maintenance or shut down of various wells that effects the composition of the associated gas stream. One result is that power units are often run at capacities that do not meet onsite demand despite being capable of doing so, because the inefficient processes require the entire associated gas flow to be processed even when it may meet quality parameters for certain power units at certain times, and require time consuming processes for e.g. separating NGLs from higher quality methane gases that reduce the gas that can be used as fuel and often result in significant NGLs that still need to be transported away or flared, resulting in losses in production volume and value generation. 
     Additionally, many systems can only treat the entire associated gas supply before sending to turbines or other application units, even though gas supply may be of high quality at various points in extraction. This means that already viable gas mixtures that can serve immediately as fuel are still put through conversion processes instead of being used directly (where wells known in the industry generally have associated gas or flare gas mixtures that may range from 30% to 90% methane content and commonly range from 65% to 80% methane content). For example, 90% methane does not need to be separated after conditioning processes are performed and can be efficiently converted into products to be used effectively to power equipment. The delay and cost of separating all gas including gas of already-sufficient quality is a significant drawback to existing systems. Bottlenecks and delays as well as insufficient processing losing portions of gas due to friction, leakage, heat loss and other system inefficiencies make existing systems and methods unattractive alternatives for many parties seeking effective gas conversion to other usable resources that will help in operating plants or generating additional revenue from existing treatment streams. 
     Combined heating and power or cogeneration applications for using well byproducts generally have a varying set of applications that require differing amounts of distinct products over time based on particular uses facilities or customers thereof. Variable inputs and outputs throughout the process occur due to equipment maintenance, component failure or breakdown, and natural occurrences that mean different subsets of wells are in operation over time, in turn providing different capacities and differing shortcomings that need to be addressed and corrected by a system. Systems known in the art include turbines and other components that have narrow operating parameters for fuel and even multi-fuel turbines would require frequent shutdowns if part of a direct line of components connected in series, remain shut down until thresholds are no longer exceeded and would require certain restart procedures. Many systems currently running do so at far less than full capacity or optimal operating parameters due to such limitations in associated gas processing and use. 
     As an over-simplified example, if a source of associated gas included three active wells supplying input gas, each may be of different composition of methane and higher carbon alkanes. If Well A is 90% methane, well B is 80% methane and Well C is 70% methane, a certain subset of well combination inputs would be within threshold parameters to operate a multi-fuel turbine requiring at least 80% methane, and other subsets would not be usable or would result in equipment shutting itself down due to heat in excess of operating thresholds. In the case where each well contributes approximately the same volume of gas and gas from each well is periodically unavailable due to maintenance operations, well A alone, well B alone, and well A and well B together, well A and well C together, and well A with well B with well C would be acceptable combinations of gas to fuel the turbine, but well C alone, and well B and well C would be unacceptable combinations of gas to send directly to the multi-fuel turbine. 
     In short, current associated gas converting technologies lack sufficient ability to adjust to a variety of associated gas compositions, are too inefficient in the manner they process those gases, and possess limitations that result in the needless flaring or waste of an extensive amount of components or constituents of those gases that have economic value and could be put to productive use while reducing negative environmental externalities. 
     SUMMARY 
     There is a need for multi-phase fluid conversion to output fuel and energy for providing customizable management for processing a volume of natural gas that is commonly extracted in aggregated form including a volume of methane and a volume of other alkanes that may be selectively conditioned, separated, and blended into a variety of different products that more efficiently uses a larger percentage of the constituents of the natural gas without over-processing those constituents or inefficiently flaring off large quantities of those constituents, in order to fuel onsite and offsite applications including combined heating and power or cogeneration applications in a responsive and dynamic manner that adapts to changing fuel demands and changing natural gas source content. The present invention is directed toward further solutions to address this need, in addition to having other desirable characteristics. Specifically, the present invention relates to a system and a method for managing variable, multi-phase fluid conversion to output fuel and energy for providing customizable management for processing a volume of natural gas including a volume of methane and a volume of other alkanes to create fuel products to be used in onsite or combined heat and power or cogeneration applications. In particular, the method, system and apparatus provide for automated feedback and control directing various gas constituents to different application units with allocations according to settings system parameters to quickly and efficiently meet demand for various products while making adjustments in real time. The method, system and apparatus of the present invention automatically adjusts to varying inputs—rerouting products, intermediate products and by products based on need, operating conditions and input composition. In this way the converting system does not have to shut off if operating parameters exceeded. It merely adjusts system flows to the correct configuration and continues processing. It therefore continues to provide products, e.g. it provides immediate power, including to power onsite systems, without reductions in capacity or bottlenecks associated with keeping certain components operating within parameters, thereby freeing more power to be transmitted and more products to be delivered. The system and method increases the quantity of products output, the range of different products output, output ratios. In example embodiments, more or less flow can be directly used a set of turbines; more or less flow can be allocated to various subprocesses; more or less flow can be converted and/or produced as dry gas; more or less flow can be diverted to natural gas liquid (NGL) conduits or wastegates for recombination into additional value-added products; NGLs can be further converted to multifuel applications or transported for external use rather than flared off; and addition power generation can occur on site. Power supply and/or flow demand do not suffer bottlenecks or reduced capacity. 
     In accordance with aspects of the present invention, the system and method controls, inter alia, the flow rate and constituent ratio of all subsystems and products thereof to convert associated gas (also referred to herein as “flare gas”) into a number of products gas by receiving a volume of flare gas or associated gas, where the volume of flare gas or associated gas includes a volume of methane (C1) and a volume of other alkanes (C2, C3, C4, etc.). The method can control both an inlet flow of the volume of flare gas and a volume of other liquids, gases that will convert, or change at least a portion of the volume of heavier (C2+) alkanes from the volume of flare gas. The method may then further process this gas or liquid to convert it to a methane rich process gas which may be combined with Flare gas to form an enriched product gas with a specific caloric value and methane number. The method can also detect when flare gas or associated gas is of sufficient quality to be used directly in applications such as turbines for power generation, and route that gas directly to those applications units that can successfully receive them. The method also uses removed constituents from gas conditioning processes and NGLs to reformulate additional product gases (blended gases) that can be used for additional applications with lower requirements or be transported for off-site use (where these gases are still of sufficient quality to be used economically rather than flared off due to transport cost exceeding the value of the underlying gas product). In accordance with aspects of the invention, the system and method provides an improved ability to adjust, redistribute, and even switch products, while also providing improved safety and reliability through redundancy and flexibility of system components, parameters, and controls. Having more product options and more routing options along with smaller, more diverse product production points also makes it less likely that the gases will have to be flared, causing negative outcomes for the environment and losing the ability to derive revenue from those resources. In this way the input gas does not all have to be converted and lower quality gases can be redirected, and the conversion system never has to be shut down due to danger of operating outside parameters and/or thresholds, because it can be adjusted according to primary purpose or need for one or more of the at least three product classes. This method multiplies uses system products and the volume of gases used before resorting to flaring unusable/waste gases, improving efficiency, production and the environment. 
     Those of skill in the art will understand that the system is capable of scaling, including by configuring subsystems and components to comprise a greater number of alternative specialized applications for routing gas and products to, as well as a greater number of intermediate steps, stages or products created as gas is converted and transported through the system during processing. 
     Unit design allows the system to convert methane and non-methane hydrocarbon alkanes (C2+) of any composition (e.g. ethane, propane and butane), including inter alia ranges from 100% ethane or nonmethane components to 100% methane, into usable products including methane rich product gas (dry gas) streams suitably for use in gas pipelines and lower methane content products including blended gas used to power e.g. combined heating and power applications onsite for a client. The system is modular, scalable and may be remotely monitored and controlled. This on-demand system produces gas of different types only as required or demanded by the applications. In an example embodiment of genset, as genset load increases or decreases the system can increase or decrease gas production based on changes in at least one of several parameters (e.g., genset feed gas pressure and/or flow rate). In an example embodiment of onsite power generation, as power demand increases the system can increase production of those gases used to fuel the appropriate application units (e.g. turbines connected to generators), while reducing flows to other production components (such that e.g. produced dry gas of pipeline quality is reduced). Process temperature control through a variety of temperature control devices and thermal energy management subsystems allows a variety of fluid heat exchangers to be used to control process cooling or flow regulating, where regulation of flow itself to different sets of subsystems or application units can be used to improve or correct system performance in relation to changing environmental and operating conditions including dynamic temperature changes. Thermal management subsystems include recuperative heating/cooling that may be used throughout system to increase energy efficiency and unit control. Throughout the system input and output streams may be used for energy exchange. 
     System product gas control and or enrichment control allow the system to perform measurement of Flare gas quality parameters including caloric value and/or Methane Number and/or composition can be used to control the gas stream to carbon ratio of the various gases (including input gas, conditioned gas, dry gas, blended gas, converted gas, and other product gases and liquids), component temperatures, and product gas quality (“Enrichment”). Conditioning and removal subsystems allow the system to perform automated generating and dispensing or rerouting of removed constituents. Components and operations or conditions thereof can be tracked where the system can monitor performance and/or monitor midstream non-methane hydrocarbon composition. Software and/or one or more control subsystems allow the conversion system to perform proportional control of product gas enrichment, thermal management subsystems, safeguards, startup/shutdown and redirect operations in process, transient/upset/spike response, warning systems, smart systems for various system configurations and embodiments including, but not limited to, the fully integrated J-T adapted system (discussed below).

     DETAILED DESCRIPTION 
     An illustrative embodiment of the present invention relates to a method and apparatus or system for managing variable, multi-phase fluid conversion to output fuel and energy for providing customizable management for processing a volume of natural gas including a volume of methane and a volume of other alkanes that may be cleaned of the other alkanes using a conversion system to create synthesis gas and other fuel products to be used in onsite or combined heat and power or cogeneration applications. In particular, the method, system and apparatus provide for automated feedback and control directing various gas constituents to different application units with allocations according to settings system parameters to quickly and efficiently meet demand for various products while making adjustments in real time. 
       FIGS.  1  through  3   , wherein like parts are designated by like reference numerals throughout, illustrate an example embodiment or embodiments of multi-phase fluid conversion to output fuel and energy for providing customizable management for processing a volume of natural gas including a volume of methane and a volume of other alkanes that may be cleaned of the other alkanes and blended into a variety of products to produce various fuels or energy, according to the present invention. Although the present invention will be described with reference to the example embodiment or embodiments illustrated in the figures, it should be understood that many alternative forms can embody the present invention. One of skill in the art will additionally appreciate different ways to alter the parameters of the embodiment(s) disclosed, such as the size, shape, or type of elements or materials, in a manner still in keeping with the spirit and scope of the present invention. 
     Referring now to  FIG.  1   , one example embodiment of the present invention includes a modular associated gas conversion system  10  with independent components or assemblies or modules (also referred to herein as “skids”) that are interconnected fluidly and/or electrically (such as power; measured data collection, analysis and transmission; control signals) to act as one unit to process associated gas stream  12  (also referred to herein as “flare gas” or “raw feed gas” or associated gas or natural gas stream). System  10 , with an associated gas stream input from a source  11 , is capable of being scaled or sized to an end-user&#39;s needs that may include, but is not limited to, a combination of a compressor skid  14  (as required), a sulfur removal subsystem  16  (sized per wellsite), storage tank  20 , a common skid  24 , separation skid  48 , conditioning skid, thermal management skid compressions skid, wet gas skid, dry gas skid, liquid natural gas (LNG) system skid, and, a product transport skid. Common skid  24  can house computerized control subsystems comprising one or more controllers  40  and the fluid and electrical interconnections with and between the other modules forming a closed loop control network to monitor, meter, and control gas flows (including feed gas), water flow, and electrical power distribution, as well as all other system parameters. Separation skid  48  can include a JT apparatus, a water removal subsystem  50 , and recuperative heating systems  54 ,  60 . Each module will be discussed in detail below. 
     System  10  can convert methane and non-methane hydrocarbon gases of any composition (e.g. ethane, propane and butane), including inter alia ranges from 100% ethane or nonmethane components to 100% methane, into usable products including methane rich product gas (dry gas) streams suitably for use in gas pipelines and lower methane content products including blended gas used to power e.g. combined heating and power applications onsite for a client. A carbon dioxide removal system can be added to system  10  if carbon dioxide levels in product gas  38  are too high to produce pipeline quality methane rich gas stream (if so desired) even after enrichment of converted or blended gas (processed gas  36 ) with system feed gas or dry gas  18 A (discussed in detail below). 
     System  10  can be remotely monitored and controlled to monitor all conditions within the system including quality of all gas streams (including transient/upset/spike responses), temperatures, pressures, flows, etc., such that safeguards are in place with warning systems and emergency shutdowns. System  10  can also be capable of remote starts and automatic remote rerouting of gas streams in response to changed demand or operating conditions (e.g. detected changes in pressure of, inter alia, input gas, conditioned gas, dry gas, NGLs and wet gas, converted gas, or blended gas). 
     In some embodiments, an associated gas stream  12 , including alkane gases, may include a varying composition that enters system  10 . Associated gas stream  12  may contain alkanes methane, propane, ethane, butane, pentane, hexane in high mole fractions as well as carbon dioxide, nitrogen, water vapor, and hydrogen sulfide. 
     In some embodiments where the well pressure is less than the conversion system requirements, a compressor skid  14  of the compressor subsystem  126  compresses the associated gas stream  12  to a defined gage pressure and transmits the associated gas stream  12  or conditioned gas stream to system  10  and components therein in an on-demand configuration. Compressor  14  can be a single or multi stage well head gas compressor that compresses associated gas stream  12  into a pressure vessel (not shown), which holds the associated gas or conditioned gas at a higher pressure than required by system  10 . The compressor  14  has a set-able outlet pressure and is on-demand. 
     A sulfur removal subsystem  16  can remove organic sulfurs and hydrogen sulfide from an associated gas stream  12  to create a sulfur free feed gas or conditioned gas  18  (also referred to as “system feed gas”). In some embodiments, sulfur removal subsystem  16  can remove the organic sulfurs and hydrogen sulfide through hydrogenation and absorption. As understood by one of ordinary skill in the art, any commercially available sulfur removal subsystem  16  is acceptable. 
     In accordance with various embodiments, the conversion system  10  includes one of more gas flow meters disposed in the system  10 , wherein gas flow at an inlet is a feedback mechanism to adjust feed gas flow rate to create the required product gas production rate. 
       FIG.  1    illustrates alternative embodiments of the present invention including a gas conversion system  10  adapted with a fully integrated Joule-Thomson (J-T) apparatus  102  (J-T adapted system). The Joule-Thomson apparatus  102  can be a commercially available or custom designed system that facilitates the Joule-Thomson effect and is fully integrated with system  10  and related systems such as software and controls as well as various system  10  processes which may include synthesis and thermal management loops. As such, the J-T adapted system functions as a single gas conversion system which receives feed gas  12  and converts it to a methane rich product gas  111  or dry gas  108  which can be enriched with a portion of feed gas  12  or converted gas  120  to adjust certain gas properties including, but not limited to, methane number and BTU value, in the form of product gas  114 . The J-T adapted system in the present configuration increases system production capacity over what is known in the art and improves product gas quality by splitting feed gas  12  into a first methane rich gas stream (dry gas) and a primarily NGL gas stream wherein the NGL gas stream is processed by system  10  into a second methane rich gas stream and combined with the first methane rich gas stream to produce product gas or blended gas  128  which may be enriched with a portion of feed gas  12 , input gas, conditioned gas, or dry gas. The integrated J-T apparatus  102  is in fluid communication with associated gas stream input  11  of the gas conversion system  10 . Generally, J-T apparatus  102  is capable of receiving the feed gas  12  or conditioned gas to separate that gas  12  into (a) a condensed liquid (J-T liquid)  110  containing primarily non-methane hydrocarbons (C2, C3, C4+) also referred to as NGLs, wherein the condensed liquid  110  in gaseous form (converted gas) is supplied to system  10  as feed gas (associated gas stream input  11 ), and (b) a dry gas (J-T gas)  108  containing primarily methane and lessor amounts of non-methane hydrocarbons (C2, C3), wherein the dry gas  108  is blended with the product gas  38  or the product gas  120  to form product gas  114 . 
     The associated gas stream  12  can be split into multiple streams at the conditioning subsystem  22 , blending subsystems ( 26 ,  28 ), or separating subsystems  32 . For example, a bypass stream of sulfur free natural gas stream  18 A (conditioned gas) can be directed to subsequent application units (e.g. pre-separation application units  146 A), and a sulfur free natural gas stream for J-T apparatus  102  feed gas  18 B. The Joule-Thomson apparatus  102  facilitates the Joule-Thomson effect, whereby the sulfur free natural gas stream for system feed gas  18 B (conditioned gas) is separated into two streams: a dry gas stream  108  that contains primarily methane and lessor amounts of non-methane hydrocarbons (C2, C3), and a condensed liquid stream  110  that contains primarily non-methane hydrocarbons (C2, C3, C4+) also referred to as NGLs. The condensed liquid  110  stream may be vaporized prior to entering the second blending subsystem  28  and/or the NGL and wet gas subsystem  52 , which produces the blended gas  128 , product gas  38 , or other unit products. One embodiment of the product gas  38 , converted gas  120  or blended gas  128  can include methane content in the range of 80-90%, carbon dioxide content in the range of 10-15%, and hydrogen content about 1%. Product gas  38 , converted gas  120  or blended gas  128  may be passed through a carbon dioxide removal apparatus  104  to substantially remove carbon dioxide  106  to form a higher methane content product gas  120  converted gas  120  or blended gas  128 . Dry gas stream  108  can be blended with product gas  38 , product gas  120  or blended in an amount equal to a predetermined blend percent of product gas  38  or product gas  120 , up to 100% of dry gas stream  108  produced, to expand system  10  production capacity and improve product gas or blended gas  128  quality including, but not limited to, adjusting for the desired methane number and/or gas BTU value in the form of a first blended or product gas  111 . Then the bypass stream of sulfur free natural gas stream  18 A can be blended with the first blended or product gas  111  in an amount equal to a predetermined enrichment percent of the first blended or product gas  111  to expand production capacity of the J-T adapted system and improve product gas quality including, but not limited to, adjusting for the desired methane number and/or gas BTU value in the form of a second blended or product gas  114 . 
     The J-T adapted conversion system can operate as an on-demand system to produce second blended or product gas  114  only as required or demanded by the applications. In an example using genset, as genset ramps up, J-T apparatus or separation subsystem  32  will increase J-T apparatus feed gas or conditioned gas  18 B flow and natural gas stream  18 A flow to meet the ramping genset feed gas need/demand; and vice versa with J-T adapted system ramping down in concert with genset demand to point of shutoff. J-T apparatus or separation subsystem  32  is capable of either matching the genset demand by controlling feed gas or conditioned gas  18 B flow and having natural gas stream  18 A follow with  18 A flow equal to a pre-determined percent of product gas  114  flow (enrichment target), or by controlling natural gas stream  18 A flow and having feed gas or conditioned gas  18 B follow with  18 B flow adjustment occurring only when  18 A flow represents an enrichment percent exceeding pre-set upper or lower enrichment percent limits. When feed gas or conditioned gas  18 B flow adjustment is necessary,  18 B flow will increase or decrease according to an algorithm determined amount to return natural gas stream  18 A to the enrichment target. Below outlines an example of on-demand based control of J-T apparatus or separation subsystem  32  by control subsystem  30  for monitoring and controlling production of product gas  114  in real time. 
     An embodiment of the present invention combines the J-T adapted conversion system with automated direct feedback control to match the feed gas (e.g. conditioned gas  18 , dry gas  108 , or wet gas  56 ) consumption rate of the supported application or one or more application units (including pre-separation application units  146 A, dry gas application units  146 B and/or NGL and wet gas application units  146 C), such as a generator, micro-turbines, gas compression engine, or other gas power unit or gas consuming unit with the product gas  114  production rate of the J-T adapted system. J-T adapted conversion system can use pressure transducer(s), pressure sensor(s) or gas flow meters as the feedback mechanism and/or component (or monitoring component or sensing component or measuring component). Pressure or gas flow at the application inlet  46 A is used to determine whether the generator is shutdown, shutting down, starting up, or transiting between low and high power settings and visa-versa. This measured pressure or gas flow is fed into a closed loop control system to adjust the J-T adapted conversion system parameters to create the required product gas  114  production rate. 
       FIG.  2    illustrates yet another example embodiment and application of the J-T adapted conversion system in a diagram depicting system components. Associated gas  12  as input gas passes through sulfur removal subsystem  16  to form sulfur free natural gas stream  18  (conditioned gas), of which a portion  18 C can be used as fuel for the gas application units of the gas conversion system  10  (e.g. pre-separation gas application units  146 A) and the remaining portion  18 D is feed gas (conditioned gas) for the J-T apparatus  102 . The conditioned gas subsystem or J-T apparatus feed gas  18 D or conditioned gas can pass through a dehydrator  124  to reduce the liquid (H 2 O) content and a compressor  126  to increase the pressure of the J-T apparatus feed gas  18 D or conditioned gas to suitable conditions for the J-T apparatus  102  to facilitate the J-T effect on the J-T apparatus feed gas  18 D or conditioned gas to form J-T products. The J-T processed feed gas  132  or conditioned gas is prepared for separation in the natural J-T separator  102  for separation into two streams: a dry gas stream  108  that contains primarily methane and lessor amounts of non-methane hydrocarbons (C2, C3), and a condensed liquid stream  110  that contains primarily non-methane hydrocarbons (C2, C3, C4+). The dry gas stream  108  can flow through main flow control  130  or other controls, controllers or monitoring or sensing components for regulation of flow to downstream compressor  126 . Condensed liquid stream  110 , which is vaporized prior to entry into second blending subsystem  28  and/or NGL and wet gas subsystem  52  is formed in gas conversion system  10  to converted gas  120 . Converted gas  120  flows through dehydrator  124  to reduce the liquid content to a substantially dry methane rich product gas  134  suitable for compression. Dry gas stream  108  and substantially dry methane rich product gas  134  or converted gas  120  flow through compressor  126  to adjust for the desired methane number and BTU value and to increase the pressure of the substantially dry blended methane rich product gas  136  suitable for filling a transportation container, such as a tanker truck  138 . The tanker truck  138  can then be driven to a remote location and connected to a valve of the valve subsystem  140  to regulate flow into the expander to fuel e.g. a remote genset. 
     In accordance with an example embodiment and application of the gas conversion system  10  employing the J-T apparatus, however, the J-T apparatus  102  is provided at a remote location. Associated gas  12  as input gas passes through sulfur removal subsystem  16  to form conditioned gas or sulfur free natural gas stream  18 , of which a portion  18 C can be used as fuel for the application units of the gas conversion system  10  and the remaining portion  18 D as conditioned gas or feed gas for the J-T apparatus  102  at the remote location. The J-T apparatus feed gas  18 D or conditioned gas can pass through a dehydrator  124  to reduce the liquid content and a compressor  126  to increase the pressure of the J-T apparatus feed gas  18 D or conditioned gas to suitable conditions for filling a transportation container, such as a tanker truck  138 . The tanker truck  138  can then be driven to a remote location and connected to valve  140  to regulate flow into the J-T apparatus  102 . The J-T apparatus feed gas  18 D or conditioned gas in the tanker truck  138  is at a pressure sufficient to facilitate the J-T effect on the J-T apparatus feed gas  18 D or conditioned gas to form J-T processed feed gas  132 . The J-T processed feed gas  132  is prepared for separation in the J-T apparatus for separation into two streams: a dry gas stream  108  that contains primarily methane and lessor amounts of non-methane hydrocarbons (C2, C3, wherein primarily is defined to be at least 51% or greater and is practice is much higher, and lessor is defined to be totaling less than 49% and in practice is much lower), and a Condensed liquid stream  110  that contains primarily non-methane hydrocarbons (C2, C3, C4+). The dry gas stream  108  has sufficient methane and BTU value to be used as a fuel for the remote application units (e.g. genset  144 ). The Condensed liquid stream  110  is pumped into another tanker truck to deliver the condensed liquid stream  110  to e.g. a tank at another location for use as feed gas to a gas conversion system  10  or appropriate application unit. The condensed liquid stream  110  may be regulated through a valve  140  to a pump  148  where it is fed to a vaporizer  150  and subsequently to system  10  where it is converted into a methane rich product gas  38  or converted gas. Sulfur free natural gas stream  18 A can be blended with product gas  38  or converted gas  120  to adjust for targeted properties such as methane number and BTU value to produce an enhanced product gas or blended gas  128  for various local and remote uses including power generation and compression. 
     Such transport, power generation, facility combined heat and power (CHP), natural gas manufacture or other production are additionally managed by the application unit product subsystem  58 , which directs unit products produced by one or more of: the one or more pre-separation applications units  146 A, the one or more dry gas applications units  146 B, the one or more NGL and wet gas applications units  146 C, and each of these one or more pre-separation applications units  146 A, the one or more dry gas applications units  146 B, the one or more NGL and wet gas applications units  146 C may be interconnected or dynamically grouped such that each may be used in place of the other or combined based on the selectable configuration of the conversion system. 
     System feed gas  12 , conditioned gas  18 , dry gas  108 , converted gas  120 , or NGL/wet gas  56  can pass through a common skid  24 . A portion  18 A of the system feed gas  18  conditioned gas, dry gas  108 , converted gas  120 , or NGL/wet gas  56  can be routed to an enrichment mixing valve  34  to blend with other gases including conditioned gas, dry gas, converted gas, or NGL/wet gas  56  from other components in an amount equal to a predetermined or variable percent of processed gas  36  (enrichment percent, % E) to form product gas  38  or blended gas  128 . The % E is set to yield and/or control certain targeted values for product gas  38  or blended gas  128  including, but not limited to, minimum methane number and maximum energy density. The enrichment percent can either be a predetermined constant or a variable set point changing with the properties of certain system gases including, but not limited to, feed gas  18  conditioned gas  120 , dry gas  18 , converted gas  120 , or NGL/wet gas  56  and processed gas  36  or blended gas  128 . In addition, enrichment of system  10  processed gas  36  increases system  10  total product gas  38  or blended gas  128  capacity. In cases where % E is zero, processed gas  36  has the same gas composition as product gas  38 , and the terms are interchangeable herein with regards to technical and legal interpretation. The remaining portion  18 B of the system feed gas  18  exits common skid  24  for subsequent processing and/or production. The predetermined enrichment percent (% E) can be determined based on measured heating value and/or methane number and/or composition of the system feed gas  18  (or associated gas stream  12 ), conditioned gas, dry gas, converted gas, or NGL/wet gas  56  and processed gas  36 , blended gas  128  and/or product gas  38 . The % E, in combination with other process controls, can be used to control gas ratios and component temperatures to adjust the methane percentage in the product gas  38 . In other words, the predetermined percentage is based on one or more of measurement of heating value, heat range methane number and composition of feed gas, conditioned gas, dry gas, converted gas, or NGL/wet gas  56  and processed gas  36  or blended gas  128  and/or product gas. One embodiment of the enrichment (or blending) strategy includes a flame ionization detector (FID) and/or gas chromatography instrument (e.g. analytes analysis) and/or an infrared composition sensor to control and/or maintain the % E at its predetermined value by measuring the heating value of various system  10  gas streams. The enrichment percent determination can be automated to vary the enrichment percentage based on real-time fluctuations in constituent compositions of certain system  10  gas streams such as system feed gas  18  (or associated gas stream  12 ). An infrared composition sensor (not shown) in concert with the FID can result in higher reliability in detecting changes in non-methane hydrocarbons (NMHC) which yield variations in gas heating value. Oxygen sensors in application units can further aid with energy content calculations to facilitate higher confidence in the analyses needed for secure control of % E and other system  10  parameters. For example, a flame ionization detector (FID) can use dry gas  40  as a reference flame (see,  FIG.  1    and  FIG.  2   ) to measure the ionization extent of system feed gas  18 . The dry gas composition is relatively stable independent of system feed gas  18  (or associated gas stream  12 ) composition. FID determined ionization values in combination with IR sensor determined composition measurements could be compared for system gases including, but not limited to, feed gas  18 , associated gas stream  12 , conditioned gas  18 , dry gas  108 , converted gas  120 , or NGL/wet gas  56  and processed gas  36  or blended gas  128 , and product gas  38  to control system parameters such as gas ratios, operating temperatures, and the constant or variable enrichment percent. These measurements, analysis, and adjustments are performed by controllers  40  of the control subsystem  30 , which is in electrical connectivity with all of the modules to receive, store, and analyze measured parameters and to transmit control commands to the modules to adjust flow meters, valves, application unit and other component temperature settings, etc. to optimize the product gas  38 . Enrichment reduces the load on conversion system  10  or, alternatively, increases system  10  capacity as well as dilutes CO2 and inert gases in processed gas  36 . 
     A portion  18 C of system feed gas  18 B (input gas) or conditioned gas can be routed to the first blending subsystem  26  to be directed to fuel the one or more pre-separation application units  146 A to be used without further processing (as in the case where input gas from wells is momentarily of high enough quality to fuel e.g. multi-fuel micro-turbines with minimal adjustment or conversion). Another portion  18 D of system feed gas  18 B (input gas) or conditioned gas can be routed to fuel the dry gas application units  146 B of the dry gas subsystem  108 . The remaining portion  18 E of the system feed gas  18 B (input gas) or conditioned gas can be routed through the separating subsystem  32  or second blending subsystem  28 , thereby operating to augment or mix with NGL or converted gas  120  (wet gas  56 ) streams to produce blended gas  128  with the proper demanded enrichment percentage, to be subsequently used by the one or more wet gas application units  146 C of the NGL and wet gas subsystem  52 . These many different alternative paths are controlled by the control subsystem  30 , which monitors and manages both the relative quantities of each of the products produced and the composition of each product, automatically and continually making adjustments in process to address changing demand, changing operating conditions or changing environmental conditions (including associated gas source conditions and gas composition). The application unit product subsystem  58  further manages use and transport of these many diverse gas products. For example, dry gas products may be transported for pipeline use, while wet gas  56  is used to generate electricity to run facilities and pre-separation gas is used for thermal management and energy to drive the method itself, while both wet gas application units  146 C and pre-separation gas application units  146 A generate additional byproducts in the form of excess exhaust heat that is then used for additional CHP applications at the facilities themselves. The flexibility of the system allows for many different formulations and combinations, where a person having ordinary skill in the art will recognize, that the method and system can duplicate the various subsystems and run them in series or parallel so as to produce additional intermediate products and by products by the automatic control of each of the many sets of subsystems using the closed loops of the control subsystem. This flexibility extends to even including application units  146  (e.g. multi-fuel micro-turbines) in subsets and subsystems of application units  146  (e.g. pre-separation gas application units  146 A, dry gas application units  146 B, wet gas application units  146 C, etc.) that can be configured to be interchangeable (such that a pre-separation gas application unit may be interconnected with other units including wet gas application units  146 C so that when demand changes the feed gas provided can be routed from a different source or component within the system effectively repurposing the pre-separation gas application unit as a wet gas application unit  146 C for a temporary period to most effectively run the system). Components of subsystems, such as compressors  14 , dehydrators  124 , or valves  140  may also be inserted or duplicated at any number of points based on requirements for individual implementations including maintaining flow, pressure, temperature, humidity or moisture content, and other properties or characteristics well understood by those of skill in the art. 
     Similarly, removed constituents from the gas conditioning subsystem  22  may be diverted by valves or components of a removal subsystem  44  to high-pressure gas storage tanks  20 , offsite transportation conduits, flaring components, or preferably, rerouted to the second blending subsystem  28  and/or NGL and wet gas application subsystem  52  for measured, selective re-blending or augmentation of other gas streams to meet demand for products with particular specifications that allow re-introduction of such removed constituents in controlled quantities. Thus, the gases can be transported through the system and added back to various gas or fluid flows where product thresholds and specifications will allow. The control subsystem  30  monitors and controls this reallocation of removed constituents in much the same manner as it monitors and controls pre-separation first blending subsystem  26  activity, and in certain embodiments, removed constituents may be controlled and reallocated as a part of the first blending subsystem  26  (or second blending subsystem  28  depending on system configuration). 
     Conversion system  10  can create pipeline quality natural gas (dry gas  108 ) from associated gas stream  12  to generate power  46  for operation of on-site equipment and off-site utilities during system  10  operation. On site power may be fueled by a portion  68  of conditioned gas, product gas  38  or blended gas  128  as well. Power  46  can be supplied to each module requiring electricity, such as the controller  42 , application units  146 , thermal management subsystems  34 , blending subsystems ( 26 ,  28 ), conditioning subsystems  22  etc. Accumulator  70  can be in-line with power production as part of the application unit product subsystem to store product gas portion  68  for startup fuel, for reserve fuel when there is a fluctuation in (transient flow) or interruption of associated gas stream  12 , and for reserve fuel for other causes of inoperability of system  10  for producing product gas  38  or blended gas  128 .  FIG.  2    is an illustration of how the product gas  38  or blended gas  128  produced from the gas conversion system  10  discussed in detail in with respect to  FIG.  1    is prepared for transportation to another site. 
     At many points throughout the process of transforming gases in the conversion system, gases can be compressed by compressors or flow through a dehydrator  124  to remove liquids from product gas  38  to form e.g. a substantially dry blended high methane rich product gas  136  suitable for compression. The substantially dry blended high methane rich product gas  136  can be metered through valve  140  for controlled pumping by pump  148  into a transportation container, such a tanker truck  138 , for delivery to another location where substantially dry blended high methane rich product gas  136  can be used as fuel for power generation units, such as gensets. Generally, additional compressors or dehydrators may be disposed along fuel conduits between subsystems, such as being disposed after the separator subsystem  32  or prior to the sets of one or more wet gas application units  146 C. 
     Recuperative heating subsystems  54  and  60  may also be deployed as part of the conversion system in accordance with one embodiment of the present invention will now be described. System power requirements have been reduced to operate, for example, the application units  146  with the use of recuperative heating systems  54 ,  60 . Recuperative energy transfer subsystem  54  is comprised of one or more heat exchangers, reducing or increasing the temperature of feed gas  66 , converted gas  120  or other gas. The modified temperature of wet gas  56  from recuperating energy transfer subsystem  54  is prepared for water removal by water removal subsystem dehydrators  50 . Similarly, recuperative energy transfer subsystem  60  is designed to increase the temperature of dry gas  108  at heat exchanger  60 A. It should be understood that heat exchanger  54 A and heat exchanger  54 B can include one or more heat exchangers of any suitable construction and type. In summary, recuperating energy transfer subsystems  54  and  60  reduce the load on the thermal management subsystems, thereby reducing application gas consumption, system emissions, and/or lower temperature gradients specific subsystems and components. 
     Conversion system  10  can operate as an on-demand system to produce processed gas  36 , dry gas  108  or blended gas  128  only as required or demanded by the applications—e.g., in case of genset, as genset ramps up, system  10  can increase feed gas  18 B, input gas or conditioned gas flow to meet the ramping genset feed gas need/demand; and vice versa with system  10  ramping down in concert with genset demand to point of shutoff. System  10  is capable of either matching the genset demand by controlling feed gas  18 B flow (metered in proportion to flow demand requirements) or matching genset demand by controlling conditioned gas flow (by adjusting production rates and quantities). Below are examples of On-Demand based control of system  10  for monitoring and controlling production of product gas  38 , blended gas  128 , dry gas  108 , and or NGLS and wet gas  56  in real time. 
     One embodiment of the present invention combines gas converting technology with automated direct feedback control to match the feed gas consumption rate of the supported application, such as a generator, gas compression engine, or any other gas consuming unit with the product gas  38  production rate of system  10 . System  10  can use pressure transducer(s) or sensor(s) as the feedback mechanism (in the form of one or more measuring components, feedback components, monitoring components or sensing components). Pressure at the application inlet  46 A is used to determine whether the subsystem or generator in question is shutdown, shutting down, starting up, or transiting between low and high power settings and visa-versa. This measured pressure value is fed into a closed loop control system to adjust the system  10  parameters to create the desired product gas  38  blended gas  128 , dry gas  108 , or NGL and wet gas  56  production rate.

This requirement is fed into a closed loop control system to adjust the flow rate (in the case of feed gas  18 B flow following flow) to create the required product gas  38 , blended gas  128 , dry gas  108 , or NGL and wet gas  56  production rate.

The system uses gas flow meters(s) as the feedback mechanism (in the form of one or more measuring components, feedback components, monitoring components or sensing components). Gas flow at the application inlet  46 A is used to determine the required production rate in real time. This requirement is fed into a closed loop control system to adjust the flow rate (in the case of feed gas  18 B or input gas) to create the required product gas  38  blended gas  128 , dry gas  108 , or NGL and wet gas  56  production rate.
