METHOD OF SEPARATING HYDROCARBON STOCK

摘要

chemical, petroleum and gas industries. SUBSTANCE: hydrocarbon stock is preheated and fed in one stream into repellent section of rectification column for isolation of heavy residual fraction. Gasoline and diesel fractions are separated in rectifying section of rectification column. Diesel fraction is steamed in bottom portion of stripping section. Gasoline and diesel fractions are withdrawn from rectification column, and heavy residual fraction, prior to its being withdrawn from rectification column, is fed from repelling section onto evaporator disposed on bottom portion of rectification column. Temperature in evaporator is maintained by level of heavy residual fraction. EFFECT: more efficient separation method. 1 dwg
