Abstract
This process comprises quenching and washing with water a gas stream derived from pyrolysis, and separating an aqueous phase from a washed gas stream; compressing, then cooling a washed gas stream; washing the compressed gas stream under pressure; passing the washed gas stream through at least one acid removal unit; drying the acid-depleted gas stream; passing the dry gas stream through at least one impurity removal unit; and feeding the purified gas stream into a cryogenic absorption unit and supplying the cryogenic absorption unit with a hydrocarbon cryogenic solvent to obtain a light gas residue, and a fraction of Chydrocarbons.
