Method for energy-saving in aromatic compounds separation by applying two gas-liquid separator

摘要

The present invention relates to a method for saving energy in an aromatic compound separation process installing each of gas-liquid separators for separating products from reaction effluence in a process reactor before and after a cooler respectively in at least one process among xylene isomerization process, a trans alkylation process of an aromatic compound, and a selective toluene transition process of an aromatic compound to apply high temperature/lower temperature gas-liquid separator in two stages before and after putting the reaction effluence from the process reactor into the cooler.
