## Background
BENEFIT CLAIM
The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/772,880 filed Mar. 5, 2013 entitled “Stacked Modular Conditioning System and Method”, listing as inventors Valmond Joseph St Amant, III and Steven Douglas Calverley.


FIELD OF THE INVENTION
A system for sampling and/or conditioning a process gas such as natural gas or the like utilizing two or more modular components, each having unique conditioning or monitoring features or the like, which components are formed to be slidingly received in a receiver so as to be stacked one upon the other for sealed engagement, forming a serial flow-through passage to provide conditioning, monitoring, or other features as the gas flows therethrough.
BACKGROUND OF THE INVENTION
It is common practice to extract fluid samples from pressurized pipelines or the like for analysis in the field or for off-site, laboratory analysis. This is especially true in the natural gas industry, where the monetary value of the gas is dependent on its compositional analysis. Likewise, the chemical and oil refining industries also have needs for extracting fluid samples from pressurized fluid sources.
Sampling and/or monitoring of the material may take various forms. Probes may be used to extract physical samples from the process gas, which may contain entrained liquid. In addition, real-time or time delayed monitoring via sensors or the like (for example, temperature, flow, liquid phase content, pH, etc) provides information on the process gas and its attributes. Corrosion coupons or other exposure indicators are likewise used to provide valuable data.
When collecting material samples for external use, as well as other operations, it may be necessary or desirable to separate liquids from the sample, or subject the material to other conditioning during the its retrieval such as, for example, pressure reduction, which may be desirable, especially in a sampling scenario involving a high pressure source.
For analytical applications including archiving, testing or the like, it may be important to avoid JT cooling to prevent condensation of vapor phase constituents. In such a case, stepped or otherwise controlled pressure reduction may be desirable to avoid adiabatic pressure drop, which may occur where to great a pressure drop is made in a single stage of pressure reduction. This should be avoided as too great a pressure drop in a single stage could result in JT cooling of the gas below its hydrocarbon dew point, resulting in sample gas composition distortion and potentially inaccurate data on the process gas stream.
Multi-stage, prior art pressure regulators can be bulky and typically are limited to two stages, and in the past, little or no consideration was given to minimizing the J-T cooling effect in third party systems.
Past modular sample conditioning systems employing two or more stages have been typically bulky and located external the fluid source, may be exposed to the elements and ambient temperature (unless insulated and/or heated or cooled to the temperature of the flow stream), and may require specialized on-site setup and calibration.
Current modular sample conditioning systems are comprised of individual sample conditioning components mounted a plate or base module near the analyzer. Examples of such systems include Parker's Intraflow system, Swagelok, and Circor Tech. These current modular sample conditioning systems are housed near the analyzer, typically in heated analyzer shelters.
GENERAL SUMMARY OF THE INVENTION
Unlike the prior art, the present invention contemplates a modular sample conditioning system which is compact, robust, easily assembled, diverse in conditioning capabilities, and able to be utilized as a probe tip or otherwise in conjunction with a sample probe or the like, or other use, and thus operate at the prevailing pressure and temperature of the process gas stream.
The present system is designed to provide a modular sampling system assembly having diverse functionality, and which can be easily customized for each application, and easily reconfigured as the need arises by a user, without the need for extensive training.
For example, the system of the present invention may be used for sampling and/or conditioning natural gas in preparation for analysis, using multiple stacked internal analytical sample conditioning components that may be utilized inside a probe that is inside a pressurized vessel such as a pipeline or other pressurized vessel or the like. A benefit of such an installation is that the components would be at the prevailing temperature and pressure of the interior of the vessel, and would not require additional shelter or enclosure, providing a reduced footprint.
The preferred embodiment of the present invention comprises a conditioning assembly comprising a receiver formed to slidingly receive conditioning components which are stacked upon one another for serial flow therethrough. The components utilized in the present device may comprise, for example, component bodies formed to receive sample conditioning sub-components such as membrane separators (e.g., phase separation membrane) regulators and regulator components, isokinetic sampling components, coalescing filters, particulate filters (screens, sintered metal, sintered plastics, thermoplastics, borosilicate glass, etc.), inertial separators, valves (i.e., throttling, needle, metering, ball, switching, etc) and others. A single sub-component could be formed to have a single function, or multiple functions, as desired.
The term “conditioning component” is not intended to be limiting as other components may likewise be used in the present invention, including sensors and monitoring components such as corrosion coupons, wireless monitoring devices such as temperature sensors (for example, thermistor sensors, thermometers, etc) wireless monitoring devices, flow meters, pressure sensors, moisture sensors, gas sensors (e.g. H2S and others) liquid detectors, etc. One functional commonality of the above components is that the fluid passing therethrough (which may comprise gas or a gas with liquid suspension, or even liquid) interacts with each said component in some capacity, be it to, for example, condition (in the case of a phase separation membrane, pressure regulator, etc) or provide data in a monitoring context (in the case of temperature sensors, flow meters, pressure sensors, etc), so the term “interacted fluid” may be used to describe fluid which has passed through any of the above components.
The present invention would be particularly suitable for providing a series of pressure regulators in stepped reduction stages to limit or prevent JT cooling, as shown in FIGS. 7-8F in the present application. An example of the use of stepped pressure reduction using pressure regulators in series may be found in Mayeaux now U.S. Pat. No. 8,616,228, the content of which are incorporated herein by reference thereto.
It is stressed that the above component list is intended to be illustrative only, and not limiting, as there are many other conditioning/monitoring components which may likewise be used with the present system. This is because the present invention is not on the conditioning/monitoring devices/techniques per se. Rather, the present invention provides a modularized system to readily assemble/customize a conditioning/monitoring solution to meet a users demands, as an easily customizable solution is not believed readily available, and there is a long felt, but unresolved need for such a solution, especially when one considers that the every fluid (in the preferred embodiment in this case, natural gas) flow has different characteristics which may require custom solutions in sampling/monitoring same.
In the preferred embodiment of the present invention, two or more modular conditioning components are formed such that the diameter of the base of each component body includes a seal which slidingly engages the inner wall of a receiver such that, with the conditioning components stacked upon one another the components are enclosed so as to allow the flow of the sample serially therethrough, forming a conditioning and/or monitoring flow through passage through the assembly. The receiver is thereby formed to receive the stacked components, and engage the stacked components so as to retain the stack within the assembly in fixed fashion in use, but allow for easy disengagement and reconfiguration, maintenance, and/or repair when desired.
The present invention also contemplates a unique sealing mechanism so as to releaseably seal the stacked components to one another within the receiver, as well as a unique method of sampling utilizing an easily customizable modular sample component assembly configured for diverse applications, including use as a sample probe tip.
Finally, the present invention contemplates a unique modular sampling/conditioning/monitoring component, which is designed to receive one or more sub-components therein of diverse functionality, so as to provide easily customizable configurations, while maintaining general uniform characteristics for sealable, serial-flow in a stacked engagement.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
Continuing with FIG. 1, the preferred embodiment of the present invention utilizes a unique modular component 1 which may have one or more sampling, fluid conditioning or monitoring functions or the like, each component comprising a component body 1′ having an outer wall 3, and first 4 and second 4′ ends having inlet 5 and outlet 5′ flow passages, respectively. The component body also has a base 7 at the first end 4, the base having a seal 7′ thereabout to engage the inner wall of the receiver (inner wall 22 of the receiver 23 is shown in FIGS. 4 and 5 and discussed in more detail infra.)
As shown, in the preferred embodiment of the present invention, the component body 1′ has an opening 10 formed in the outer wall 3 of the unit forming a cavity 9′ formed to receive a sub-component 9 (and which may include o-ring seals 11′, 11′′), which sub-component is configured to provide the desired functionality with regard to fluid conditioning, monitoring, etc, and is designed for inter-changeability engaging the passages formed in the modular component 1. It is noted that the opening 10 formed to receive the sub-component may be threaded or not, depending upon the type of sub-component used and its operation. For example, presently the opening 10 may not be threaded for use with the pressure regulator stage as shown because it must move to operate, although many other sub-components would threadingly engage opening 10, as currently envisioned.
The exemplary sub-component 9 shown in FIG. 1 comprises a pressure regulator stage or reducer (for example, a first stage regulator), which is inserted into the opening 10 and engages same (sealed via o-ring, for example), such that said regulator stage or the like is situated largely within the component body, and does not protrude past the largest diameter of the sidewall.
As shown, the sub-component 9 (as indicated, a regulator stage) is configured to engage the inlet 5 and outlet 5′ flow passages in its operation.
A sealing mechanism in the form of an o-ring is shown at the end of the component, so as to provide a fluid-tight seal between adjacent, stacked components.
The preferred embodiment of the present invention employs multiple stacked components to provide flow through modular conditioning, monitoring, or the like. The stacked components could be secured to one another (via example, threaded or snapped connections, or external brackets or the like), and may be simply stacked in sliding engagement with a receiver (the example illustrated in the present FIGS. 1-6) or cartridge, or may be some combination thereof. The components are selected depending upon the fluid conditioning or monitoring required, then stacked in the desired order of conditioning/monitoring.
Continuing with FIGS. 1-6, first 13, second 13′ and third 13′′ components are shown stacked upon one another (FIG. 2), the first 13 component having installed as its sub-component 12 an inlet filter, membrane filter, coalescing filter, particulate filter or the like, the second 13′ component having at its sub-component 12′ a stage one regulator, and the third 13′′ component having a sub-component 12′′ comprising a second stage regulator.
As shown, each component has at its second end 4′ a sealing mechanism (11 in FIG. 1 or 51 in FIG. 2) such as an o-ring or the like situated about the outlet flow passage 5′ to provide sealed fluid passage communication to the first end 4 of the stacked component or other item engaged thereto (which may serve as a reference port for a regulator, and each component has at its first end 4 a base 7 which has a seal 7′ about its outer perimeter formed to engage the inner wall 22 of receiver 23.
Continuing with FIGS. 1-4, to accommodate sub-components such as the regulators or the like shown in the exemplary second 13′ and third 13′′ stacked components having an outlet 16, 16′ emanating therefrom, the outer wall 3 of the component body is formed to have a slightly lesser width 17′ (or diameter in the case of a cylindrical configuration) than the inner wall 22 (or ID in the case of a cylinder) of the receiver 23 for sliding engagement and also so as to form a space 18 therebetween (in the present, preferred embodiment, the space being about 0.005′′), said space 18 enclosed via opposing component base seals 7′, 7′′ engaging the inner wall of the receiver, forming an enclosed passage allowing outflow 20 from the sub-component outlet 16 to inlet passage 21 leading to the next component, in the present example, a stage two regulator. In the illustrated, exemplary embodiment, outlet flow passage 26, 50 provides the reference pressure for the stage two regulator stacked thereupon.
Continuing with FIGS. 1-5, a threaded insert 27 is applied to the first end of the first component 13 to engage the threaded opening 27′ of the receiver 23 or cartridge, to retain the stack of components solidly within the receiver or cartridge, and apply pressure to the stack of components to facilitate the o-ring sale between said components, while the flow passage formed therethrough (in FIG. 4, inlet 53, outlet 54) allows passage of the flow to or from the components. Also, a transition piece 28 may be provided to engage the second end of the last component forming the stack, the transition piece engaging the outlets of said last component and directing same via passages to form the desired outflow for the system, as well as being formed to engage the inlet of the receiver, cartridge, probe or other item having its inlet engaged thereto.
As shown in FIGS. 5A-C, the cartridge with modular sample components stacked therein may be mounted to the tip of a fluid probe or the like via a probe tip adapter to allow the stack to serially engage a process fluid stream. In such a scenario, fluid from the fluid stream would into the probe tip, through the first then subsequent conditioning components in serial fashion, and thereby provide a flow of conditioned fluid from the process fluid stream at prevailing fluid pressure and temperature to the probe, providing an analytically correct sample, while lessening any JT cooling effect.
Another example of stacked conditioning components, in this example contained in a cartridge configured to form a probe tip extension 70 mounted to a probe, can be found in FIGS. 6-8D. As shown, a probe tip as situated at its opening 71 a phase separation membrane 72, coalescing filter, particulate filter, or the like, followed by a receiver 73 formed in the cartridge to contain first 74, second 74′ and third 74′′ stage, stacked pressure regulator sub-components side-mounted 75 in three respective conditioning components 76, 76′, 76′′ of a uniform outer diameter (OD) 77 slidingly engaging the inner diameter (ID) 78 of receiver 73. While pressure regulators as conditioning sub-components are illustrated as used, conditioning sub-components of other functions may be selected depending upon the fluid conditioning desired, then stacked in the desired order of conditioning.
The cartridge with modular sample components therein is shown mounted to a tip 79 of a probe 80 or the like (and may include a 4th stage adjustable regulator 81 with opposing threaded ends for engagement therebetween) to selectively engage a process gas stream in a pressurized vessel such as a pipeline, so that the fluid passes into the probe tip, through the phase separation membrane 72 then the first and subsequent conditioning components, and thereby provide a flow of conditioned fluid from the process gas stream at prevailing pressure and temperature to the probe, in a manner which could lessen or prevent JT cooling.
In summary, the present invention contemplates the unique and useful improvement of providing modular conditioning components, each having their own function and specification, but designed to be interchangeably stacked depending upon the conditions and desired outcome which may be used as a connected stack and/or placed into a receiver or cartridge, thereby providing a custom conditioning and/or monitoring solution.
The invention embodiments herein described are done so in detail for exemplary purposes only, and may be subject to many different variations in design, structure, application and operation methodology. Thus, the detailed disclosures therein should be interpreted in an illustrative, exemplary manner, and not in a limited sense.
