METHOD FOR ISOLATION OF AROMATIC HYDROCARBON FROM NONCONDENSED GASES IN MANUFACTURING STYRENE Russian patent published in 2005 - IPC

Abstract RU 2263099 C1

FIELD: chemistry of aromatic compounds, petroleum chemistry, chemical technology.

SUBSTANCE: method involves carrying out three-stage isolation of aromatic hydrocarbons by separation, absorption and separation using at absorption stage atmosphere distillate off (TS 38.401194-92) as absorbent and prepared in manufacturing oil-polymeric resin by catalytic method. Invention provides reducing loss of aromatic hydrocarbons and improving economic indices of process in manufacturing styrene.

EFFECT: improved method for isolation.
