Treatment of Off-Gas in the Production of Para-Xylene by the Methylation of Toluene and/or Benzene

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...
