HYDROCARBON RAW STOCK-BASED MOTOR FUEL PRODUCTION PLANT (VERSIONS) Russian patent published in 1998 - IPC

FIELD: motor fuel production. SUBSTANCE: plant is intended to be used for producing motor fuels for local needs, basically at small or out-of-the-way oil and gas condensate deposits wherefrom export of raw stock is unprofitable. Plant contains evaporator-equipped fraction separator, hollow of which is connected with hollow of the diesel fuel-collection tank and, through gasoline fraction vapor collector, with gasoline collection tank. Invention consists in that, plant is additionally provided with several fraction separators, each of them communicating through gasoline vapor condenser of another fraction separator with gasoline collection tank. Condensers are made in the form of tubular heat exchangers. According to another version, in addition to above-indicated supplementary equipment, plant is also provided with buffer and collection tanks, hollows of fraction separators communicate with buffer, and collection tanks through diesel fraction vapor condenser and buffer tank are additionally connected through vapor superheater with each of the indicated tanks. There are also cut-off means installed in pipelines between communicating units. Furthermore, there are diesel fuel vapor distributors in the form of perforated tubular elements installed inside hollows on pipelines connecting them with buffer tank. EFFECT: improved construction. 6 cl, 2 dwg
