TREATMENT OF OFF-GAS IN THE PRODUCTION OF PARA-XYLENE BY THE METHYLATION OF TOLUENE AND/OR BENZENE

摘要

A process for removing contaminants from an off-gas stream generated by the methylation of toluene and/or benzene by methanol to produce para-xylene. The treated off- gas stream, which contains C4- hydrocarbons, may be further processed in an olefins plant/process to yield valuable light alkanes and olefins.
