SYNTHESIS OF HYDROCARBON AND EQUIPMENT FOR IT

摘要

PURPOSE:To prepare LPG, gasoline, etc. efficiently, by cooling a product from gasoline synthesis reaction process and passing it through a series of specified separation processes. CONSTITUTION:A raw material gas (mixture of H2 and CO) preheated to about 150-350 deg.C in a heat exchanger E-101 is fed into a gasoline synthesis reactor R-101. The resultant reaction product is cooled to below 100 deg.C in heat exchangers E-101, 102 and sent into a separator V-101. Generated gas is treated in an absorption tower T-101 and a part of it is recylced to the reactor R-101, while the remainder is taken out through a pipe 8 for use as fuel gas. 2C or higher liquid hydrocarbons are treated in a deethanizer T-201, fractions below 2C is taken out as fuel gas and other fractions are sent into a debutanizer T-200 to take out 5C and 6C fractions as gasoline through a pipe 17 and recycle 7C or higher fractions to the absorption tower T-101 through a pipe 18.
