Abstract

A gas-liquid extractive stripping process which uses at least one preferential physical solvent in at least one solvent loop, each loop passing through at least two unit operations: extractive-stripping and distillation. At least the first extractive-stripping operation may additionally comprise a rectification section on top of the extraction section. Three products are made from streams of thermally cracked gases or refinery gases: a hydrogen-rich gas stream, a methane-rich gas stream, and a C2=+ hydrocarbons stream which is the feed stream for the conventional fractionation train of an olefins manufacturing facility. Ethylene can be economically produced from the C2=+ hydrocarbons product stream at a recovery of at least 99.5% and a purity of at least 99.9%.
