Abstract:
Removing ethanol from fuel by admitting the ethanol-containing fuel into a contained amount of water which is then mixed such that the ethanol-containing fuel may readily be separated into another container. Water and ethanol have an affinity for each other and separate away from the now ethanol-free fuel, and the water/ethanol mixture settles to a lower portion of the container. Once separated, the ethanol free fuel is readily removed into a separate container. The alcohol (ethanol) and water mixture is a valuable by-product of the invention, and is collected separately.

Description:
[0001]    This is a privately conceived and funded invention free from any governmental involvement. This is a regular patent application that is being timely filed within the time period allotted from a Provisional Application entitled the same and filed on Nov. 5, 2012 having the same inventor as hereof and awarded Ser. No. 61/706,184. 
     
    
       [0002]    The sole inventor has developed a new and unique configuration that enhances ethanol removal from gasoline by an inexpensive privately maintained accessory. The inventor, Jason C. Jones, has achieved a concept involving a novel structure that is worthy of patent protection in the fullest. The invention is presented herein by reference to figures, drawings, photographs and associated description which together amply demonstrate the novel and patentable features, method steps and structure of the invention. 
       BACKGROUND AND FIELD OF THE INVENTION 
       [0003]    This invention relates to the field of small gas powered engines and more particularly to private individual users of such equipment. The inventive method hereof finds particular strength in regard to novel steps and structures taken to improve our daily recreational-oriented activities. 
         [0004]    It is recognized that a wide gamut of piston driven small engine applications should not—and must not—use ethanol blended gasoline. However, the blending practices and laws governing ethanol content are far from uniform and thus the user remains at risk. Protection of such an owner/user is a goal and accomplishment of this invention. 
         [0005]    Ethanol test kits have become readily available in order to allow private users to test for the presence of and amount of ethanol in service station provided petroleum based fuel commonly referred to as E10 gasoline. The 10 signifies that up to 10 percent by volume is ethanol compared with the pure fuel at issue. Advocates seek instances wherein the percentage of alcohol (ethanol) in gas should be increased to 15% or “E15”. 
         [0006]    Almost all conventional engine warranties only approve use of 10% (“E10”) fuel, and the factory engine warranty is voided if anything above 10% is employed. In actual practice, the percentage of ethanol varies with each and every fuel delivery to the commercial usage purchase location. Thus engine warranties, unknowingly, are often in danger of being voided without the owner/users knowledge or intent. 
         [0007]    To further compound the above-noted problem, many service stations have stopped selling ethanol free (“E0”) gasoline at all. And, some states even mandate that ethanol must be bended into petroleum based gasoline and there are no exemptions from such governmental-mandated ethanol blending laws. A strong profit motive for more and more ethanol in fuel is backed by Governmental subsidies in the ethanol blended gasoline arena. In any event, however, ethanol percentages are not at all uniform and are generally outside the owner/users control. Nor is an accurate percentage blend required in printed form on a vast number of service station fuel island pumping equipment. 
         [0008]    Moreover, some states are now removing the requirement that service station pumps must be accurately labeled as to whether or not the fuel being sold by that particular location does or does not actually contain ethanol. The ultimate owner/user is thus the single most entity that is at risk since some engines must not be subject to any ethanol containing fuel at all. Accordingly, a dangerous warranty and costly equipment repair or replacement situation has developed. It remains as established fact, however,—labeling requirements aside—that ethanol must not be used in certain vehicle engines. 
         [0009]    Indeed, the presence of ethanol—regardless of percentage amount or labeling requirements—is deemed very harmful to every gasoline powered engine. Highly summarized, ethanol is harmful because its presence in fuel:
       Rots and weakens rubber hoses:   Damages carburation parts:   Hurts fuel economy;   Attributes engine ping to engine operation;   Absorbs water and water-carried impurities into engine fuel;   Aversely shortens fuel storage life;   Damages fuel injectors, and rubber/plastic engine components;   Dries out and/or cracks hoses, seals and the like.       
 
         [0018]    The above-noted summarization of harmful effects is not intended to be exhaustive. Other harmful effects are known to result from ethanol but may not be stated above. Be advised, nevertheless, that ethanol is added locally—not at the refinery. Thus no uniformity as to ethanol amounts in fuel being purchased is to be expected. 
         [0019]    Recreational vehicles, in particular, are achieving high popularity and are very seriously in danger from ethanol presence in their fuel. Ethanol should not be used in 2 cycle engines as are today employed in most tools, lawnmowers, watercraft, snowmobiles, motorcycles and off-road 4 wheelers, dune buggies and the like. Antique cars, in particular, and many luxury vehicles as well should not use ethanol blended fuel. 
         [0020]    Of paramount importance to all users is safety. And, such safety requires sound and safe equipment with focus on reliably expected octane and energy ratings. Reliability and safety are paramount factors behind the concepts of this invention as is further explained below. An owner, of course, desires reliable octane and energy performance from the fuel being consumed. Ethanol-containing fuel is susceptible to water contamination and phase separation, either of which deteriorates the performance factors of the fuel. 
         [0021]    In general, ethanol is touted as a solvent, cleanser, degreaser, drying agent, antifreeze substitute, water-absorber and so-called octane enhancer. In actual practice, however, ethanol is highly unstable since it is attracts and absorbs water. Water in fuel is not desirable at all and degrades octane and energy performance characteristics. 
         [0022]    Water and petroleum do not mix and thus potential harm is readily involved whenever ethanol is used under non-controlled situations such as those existing in our service-station-oriented environment. In short, ethanol blending can readily introduce many operational deficiencies that can cause serious octane/energy depletion and may result in harm to engine operation. Indeed, this invention takes advantage visibly of certain aspects of these stated deficiencies in accordance with its operational and structural arrangement. One ethanol factor considered a marked disadvantage is taken as an engineering principle that becomes a marked advantage in the invention. A new and unusual system arrangement and novel discovered methods concerning ethanol are disclosed and employed to advantage by the principles and structural operation of this invention. 
         [0023]    A large majority of today&#39;s small engine users take specialized 5 or 10 gallon containers with them to obtain relatively small quantities of gasoline at their local service stations. Small trucks/RVs conveniently store extra fuel space. These convenience containers, as is well known, allow users to safely carry away a fixed quantity of ethanol-containing fuel from the local service station or distribution center. Ethanol must be removed from such containers for a great variety of reasons and equipment as was noted above. This invention readily accommodates such portable containers while it is not limited thereto. 
         [0024]    Highly summarized, this ethanol remover invention provides a small compact mixing container in pipe or cylinder form for receiving a fixed quantity of regular water as may be drawn for example from a tap and introduced into said pipe/cylinder. According to the invention, Egas is pumped under pressure into the water contained within the mixing container. Such a cylinder may conveniently be made from a length of black plastic three inch diameter Schedule 40 pipe. A two foot length of such pipe will readily hold about 3 quarts of tap water introduced therein by a gravity feed fill tube. Three quarts of water, experience has shown, will suffice for several gallons of ethanol-containing gas 
         [0025]    Associated with that water containing pipe cylinder is a mixing device for mixing or shaking the Egas under pressure into the water quantity stored in the mixing container. The inventor has discovered that the ethanol mixes and stays with the water in the bottom portion of the mixing cylinder; while ethanol free “E0” gas rises to the top of the contained water in the cylinder. Water mixed with removed ethanol takes on a milky white or murky color. The invention use this color change to advantage in his invention, as explained further below. 
         [0026]    Associated with and positioned at the top of the cylinder is a clear sight tube which visually exposes ethanol free murky color achieved by mixing action within the cylinder. Vigorously mixing admitted Egas with the contained water causes a distinct separation of pure gas and ethanol as mixed under pressure with the cylinder-contained water. In operation, a flexible hose is inserted into the portable Egas container and such Egas is pump driven through appropriate valves and tubing into the mixing chamber. Windshield spray nozzles have achieved a satisfactory mixing action although other mixing devices may be employed. The Egas and water, vigorously mixed together, causes the ethanol to fully separate from the gas due to the affinity that ethanol exhibits for water. This mixed ethanol and water conglomerate and sink to the bottom of the cylinder whereas E0—ethanol free gas—rises to the top of the contained water in the cylinder. 
         [0027]    A simple visual inspection via the inventions transparent sight tube allows the E-removed gas to be drawn away into another container. The invention tests have shown that the shape of the mixing container is not critical. Also the inventor has discovered that plates within the mixing container can be used to advantage for removal of air bubbles should those bubbles prove harmful. It is the inventor&#39;s experience that the apparatus of his  FIG. 3  does have bubbles, but he has found that their presence does not adversely affect the result achieved by his ethanol removal system. Indeed, tests confirm that 100 percent of the ethanol was cheaply and safely removed from the Egas that was originally introduced into this private ethanol removal system of  FIG. 3  and that the bubbles did not affect the desired results. 
         [0028]    Accordingly, what has been needed—but was not yet provided prior to the advent of this invention—was a simple yet straightforward solution to the above-described ethanol removal problem. On a private individual basis a simple effective tool has been provided which utilizes a careful balance of existing technology with inexpensive common place component parts to achieve a new and unexpected result and desired performance. This invention thus provides an ethanol removing system via simple effective means from ordinary economical components and yields a major improvement in fuel handling and care for small engine equipment for a variety of equipment types. 
         [0029]    Additionally, many of the above noted factors bring the convenience and safety of the individual engine owner into play whereby he may more readily provide safety and convenience for his piston driven equipment irrespective of its use or location. In short summary, what is needed is a better way, and a new improvement and combination of standard components has been provided which in combination yield both a new and useful method and a novel apparatus for private ethanol removal. 
       SUMMARY OF THE INVENTION 
       [0030]    Please see the enclosed pictures and sketches taken together with the written description. The private user ethanol removal invention, it should be noted, is not yet fully commercially developed nor is it priced or available beyond a Research &amp; Development final prototype stage. It has not yet been made available to the public nor is it on sale. Instead, it is approaching the final stages of perfection and the filing of this regular patent application takes place before any sale, disclosure or public use of the invention has taken place. 
         [0031]    An improved method and/or apparatus of removing ethanol from fuel by a removal system comprising the steps described and depicted in  FIGS. 1 through 3  hereof by virtue of mixing ethanol-containing gasoline with water and comprising providing a container of water into which ethanol-containing gasoline may be admitted under slight pressure; mixing the fuel under said pressure with said contained water; settling the mixture of water and ethanol toward a lower portion of said container; separating the ethanol free fuel from the settled water and ethanol mixture; and removing the ethanol free fuel from said container. 
         [0032]    A method of removing ethanol from fuel in a system having contained water, by the steps consisting essentially of: 
         [0033]    mixing ethanol-containing fuel into the contained water thus allowing the fuel to float to the top of the contained water in the system; 
         [0034]    continuing to introduce more ethanol-containing fuel into the system during a continuous operation of said ethanol removal; and 
         [0035]    draining ethanol free fuel off the top of the water. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
         [0036]    Several sketches and photographs ( FIGS. 1 through 3 ) illustrate the principles of the method and apparatus of this invention. In order to help the Patent Office Examiner better understand my invention, the inventor herein describes the apparatus and process involved by reference to these various Figures. 
           [0037]      FIG. 1  includes  FIGS. 1A ,  1 B and  1 C; 
           [0038]      FIG. 2  is a sketch depicting a component layout; and 
           [0039]      FIG. 3  shows the inventive system presented upon a mounting board. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0040]      FIG. 1A  is a basic block diagram of the ethanol removal system invention.  FIG. 1B  depicts a sketch of additional details concerning the system of  FIG. 1A . In  FIG. 1A , E10 or E15 fuel in container  20  is supplied via pump pressure from pump  22  into a mixing and separating chamber  25 . Ethanol free gas is separated by the mixing element  30  at component  25  in the manner described previously. One of the difficulties of the removal system was how to get the pure gas (ethanol free gas, E0) out of the system into another container or holding tank  35 .  FIG. 1C  depicts some of my early considerations concerning filtering layers  36  with several different configurations of surfaces and openings therein being provided so as to assist in and enable the E0 removal process with a bubble reduced system operation. 
         [0041]      FIG. 2  is a sketch depicting a component layout useful for explaining the operation of my ethanol removal invention. In the sketch of  FIG. 2  a battery operated system is shown. The operation of  FIG. 2  and the components of  FIG. 3  are essentially the same. Thus the detailed description of the actual system of  FIG. 3  will suffice for both Figures. 
         [0042]      FIG. 3  shows the system  100  presented upon a mounting board  101 . The overall height of the system is about four feet and thus it may conveniently be mounted on a wall or it can be made in a free standing configuration as desired. In my  FIG. 3 , a round mixing pipe is employed whereas in my  FIG. 1C  a square mixing container also will work well. These various figures of my drawing further demonstrate the method and apparatus of the invention and are believed to be self explanatory in view of the written description that follows. 
         [0043]    For ease of presentation, my invention has been shown and described by my coined term as “Ethanol-B-Gone™”. My novel Ethanol-B-Gone device is designated in  FIG. 1A  as device  100 . That device  100  is depicted as positioned to the left of a typical 5 gallon Egas input container  20 . The container  20  is filled with an ethanol containing gas that would be purchased from a local service station or distribution center. Extending from container  20  is a tube  36  connected to the suction side of pump  22  that has its pressure supply side connected through a filter  42  which is connected in turn to an input supply line  50 . Gauge  45  is in line on the input side and gauge  45  monitors the pressure applied by pump  22  to the inlet supply line  50 . In this configuration input line  50  is connected to the inlet bottom side of a standing three inch diameter PCV pipe  70 . 
         [0044]    Also connected to the bottom of pipe  70  through appropriate valves is a standing water fill pipe  88 . Fill pipe  88  is used at the start of an ethanol removal operation by placing about 3 quarts of regular tap water into the interior of pipe  70 . Pipe  70  is thus partially filled with tap water before an ethanol-containing gas “Egas” is introduced into pipe  70  from container  20  via activation of pump  22  and inlet line  50 . Pump  22 , with about 4 to 7 pounds per square inch of positive pressure, forces Egas into the pipe  70  via line  50 . 
         [0045]    A mixing action takes place between the contained water and the incoming Egas. This mixing action is signified by a swirling motion as symbolically depicted by arrows  75  in  FIG. 1B . Mixing or swirling the Egas (see arrow pattern  75   FIG. 1B ) under pressure into the water stored in pipe  70  results in a new and novel discovery and highly advantageous result. I discovered that the ethanol mixes freely into the water and stays with the water in the bottom portion of the mixing cylinder  70 , while ethanol free E0 gas rises to the top and floats on the upper water surface in cylinder  70 . 
         [0046]    Positioned at the top of cylinder  70  is a clear sight tube  80  which visually exposes the results achieved by this mixing action within cylinder  70 . Vigorously mixing admitted Egas with the contained water causes a distinct separation of pure gas and the ethanol as mixed under pressure with the cylinder-contained water. A line of demarcation  180  is present in sight tube  80  as the purification process is being concluded. It is a simple matter to note the slowly rising demarcation line  180  rising in sight tube  80  and thus recognize that the ethanol removal process is drawing to a close. 
         [0047]    Windshield spray nozzles located at the output of line  50  with the pressurized jets input into the swirl developing in tube  70  have proven to achieve a satisfactory mixing action as ethanol containing gas is forced into pipe  70 . The Egas and water, vigorously mixed together, causes the ethanol to fully separate as a murky liquid from the purified gas due to the strong affinity which ethanol exhibits for water. In the sight tube the mixture of ethanol and water due perhaps to the presence of tiny bubbles is a milky white color which readily allows the operator to clearly identify the demarcation line between pure gas and the ethanol-removed byproduct liquid. 
         [0048]    This ethanol and water conglomerate mixes together and stays in position toward the bottom of the cylinder  70 , whereas E0—ethanol free gas—rises to the top of the water in cylinder  70 . A line of clear demarcation  180  exists between the mixture and the purified Egas. That line  180  begins to appear and moves upward in sight tube  80  as the removal operation is being concluded. 
         [0049]    Visual inspection via the transparent sight tube  80  allows the E-removed gas to be drawn away into another container  35  as ethanol free gas. I have tested and confirmed that essentially 100 percent of the ethanol and water has thus been removed from the Egas originally introduced into my private ethanol removal system  100 . An important by product of this invention is the murky ethanol and water mixture drained from pipe  70  after ethanol removal is accomplished. 
         [0050]    Valves connected to the bottom of pipe  70  easily and quickly allows for removal of this byproduct. I have found several valuable uses for the byproduct including use as a purifying agent, solvent, degreaser, anti freeze supplement and a drying agent with chemical properties. Other uses are being researched at this time. 
         [0051]    While my pictures and sketches herein are shown in a circular form as components of my invention, pipe  70 , water fill tube  88  etc. may take any number of shapes while still accomplishing my stated objectives as described herein. Please note that the plastic pipe components are very economical, and thus this system is inexpensive to produce in quantity, and achieves a salutary result not heretofore found in the prior art. Other shapes and configurations are thus possible without departing from the scope and power of this invention. 
         [0052]    What has been depicted and described is a new method and apparatus for ethanol removal. The invention is safe, easy to use and achieves objectives not heretofore achieved by any other known prior art devices. The invention provides many non obvious features and advantages over the prior art.
