摘要：
A process for the removal of trace quantities of polynuclear aromatic compounds from the vapor effluent of a hydrocarbon dehydrogenation zone containing normally gaseous olefinic hydrocarbons, trace mononuclear aromatic compounds and trace polynuclear aromatic compounds by contacting the hot vapor effluent of a hydrocarbon dehydrogenation zone with a cold lean liquid absorption stream to absorb at least a portion of the trace polynuclear aromatic compounds to produce a rich liquid absorption stream and a gaseous olefin-containing hydrocarbon stream having a reduced concentration of polynuclear aromatic compounds.
