TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred System: The system further comprises a post-reactor network that comprises at least one co-product storage vessel and at least one biodiesel storage vessel. The batch reactor is in fluid communication with the post-reactor network. The system additionally comprises at least one reagent storage vessel and at least one reagent mixing vessel, which are in fluid communication with the batch reactor. The post-reactor network further comprises at least one separator holding vessel that is in fluid communication with the batch reactor and/or the at least one co-product storage vessel; at least one separator that is in fluid communication with the batch reactor, the separator holding vessel and/or the at least one co-product storage vessel; or at least one polishing vessel that is in fluid communication with the batch reactor, the at least one separator holding vessel, the at least one separator, the at least one co-product storage vessel and/or the at least one biodiesel storage vessel. The separator is a liquid phase separator or a centrifuge. The polishing vessel comprises several wash heads (preferably 1-20 wash heads). The several wash heads are disposed in the roof of the polishing vessel, on an internal wall of the polishing vessel, on a pole inside the polishing vessel and/or on a rod inside the polishing vessel. The post-reactor network further comprises at least one drying vessel that is in fluid communication with the at least one polishing vessel, the at least one biodiesel storage vessel and/or at least one reagent storage vessel. The drying vessel comprises a heating element and a vacuum. The system further produces a co-product. The baffle comprises a material selected from steel, carbon steel, stainless steel, chromium plated steel, copper, aluminum, metal alloy, thermally conductive polymer, polyvinyl chloride, epoxy, fluroroplastic, polypropylene, polyimide, polyacetal, polycarbonate, acrylonitrile-butadiene-styrene, polyetheretherketone, polybutylene, polyphenylene oxide, polyphenylene sulfide and/or liquid crystal polymer and is fixed at an angle of 90?0 to an interior wall of the batch reactor. The baffle is heated at 50-200degrees F and comprises piping that is in fluid communication with a heat source. The piping is disposed substantially vertical to the height of the batch reactor. The heat source is steam. The batch reactor comprises 2-10 baffles. The at least one baffle comprises a cavity that allows the baffle to be substantially offset from an interior side of the batch reactor. The cavity is formed from two arms of the baffle disposed perpendicular to a main body of the baffle or a concave nature of the baffle. The baffle further comprises a second cavity, which is disposed in the main body of the baffle. The pump and the miser reintroduce a portion of reaction mixture into a remaining portion of reaction mixture to provide a substantially homogeneous reaction mixture.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further involves mixing the at least one reagent with a second reagent to creating a reagent mixture; and delivering the reagent mixture to the feedstock in the batch reactor to create the reaction mixture. The method also involves delivering a second reagent to the feedstock in the batch reactor; and transferring the non-biodiesel composition to a co-product storage tank. In the method, the feedstock comprises an organic oil, an animal fat and a plant source. The reagent is an alcohol; or catalyst. The polishing step comprises a polishing agent. The method further involves processing the co-product to provide a food grade product, pharmaceutical grad product, a livestock feed grade product or a generally recognized as safe product; drying the polished biodiesel product to obtain the biodiesel product by heating the polished biodiesel under vacuum; condensing vaporized residual reagent and polishing agent, and transferring condensed residual reagent and polishing agent to a reagent storage vessel. The process further produces a co-product. The predetermined time and the predetermined conditions for processing the feedstock are as given in the specification e.g. temperature range is 60-70degrees F, processing time is 475-500 minutes, volume of methanol is 20 vol/vol.%, amount of caustic soda is 475 lbs and amount of oil is 8650 gallons. Preferred Components: The co-product comprises (vol/vol.%) glycerin (30-40, preferably 34-38), fatty acids (50-60, preferably 55-60) and alcohol (5-10, preferably 6-7), a fuel source that fuels the batch reactor system and a fuel extender. EXAMPLE - In a batch reactor, soybean oil (6500 gallons) was added, which was heated to 135degrees F. Separately in a reagent mixing vessel, caustic soda (sodium hydroxide) (500 lbs) was added to methanol (99.9% pure, 2200 gallons), which were mixed together (60 minutes). The caustic soda-methanol mixture then was injected into the soy oil in at a rate of 200 gallons per minute (gpm), while an agitator of the batch reactor was spinning at 144 rpm. Immediately, a re-circulating 600 gpm pump and a mixer of the batch reactor was turned on. The agitator, pump and mixer of the batch reactor were allowed to continue to blend and mix the reaction mixture for 90 minutes, at which time the reaction for producing soy methyl esters was completed. Then the reaction mixture was transferred using the same 600 gpm pump to a separator holding vessel from which the reaction mixture was fed to a pair of separators. The separators forced (at 25 gpm) the heavy phase (40% glycerin, 50% fatty acids, and 10% methanol) away from the light phase (90% methyl esters, 7% methanol, and 3% water and soaps). The light phase, which was a crude biodiesel of soy methyl esters, was transferred to a polishing vessel and showered with an acid-treated liquid (water) polishing agent (phosphoric acid (35%); 4 gallons per 3000 gallons of water) to pH balance (pH of 6.5-7) the crude biodiesel soy methyl esters and to wash out residual glycerin, methanol, and soaps. The acid-treated liquid (water) polishing agent (3000 gallons) washed 17000 gallons of crude biodiesel to form methyl soy esters biodiesel.
