FIELD: petrochemical processes.
SUBSTANCE: method provides for three-stage isolation of aromatic hydrocarbons in the separation, absorption, and separation stages using, as absorbent, ethylbenzene rectification bottom residue. Loaded absorbent containing diethylbenzene isomer mixture serves as starting material for production of alkylaromatic hydrocarbons including divinylbenzene.
EFFECT: reduced loss of aromatic hydrocarbons and improved economical efficiency of styrene production process.
