PROCESS FOR THE RECOVERY OF WATER AND VALUABLE ORGANICS FROM WASTEWATER IN THE PRODUCTION OF AROMATIC CARBOXYLIC ACIDS

摘要

A process for the removal and recovery of water and organics from a liquid stream in a chemical process is disclosed. The process comprises contacting the liquid stream with a polymeric adsorbent to form purified water. Subsequent steps include regenerating the polymeric adsorbent resin by contacting the polymeric adsorbent resin with polymeric adsorbent resin regeneration solution to form recovered organics, washing the polymeric adsorbent resin with a washing solution comprising substantially water, and removing remaining regeneration solution adsorbed on the polymeric adsorbent resin by contacting the resin with a fluid comprising hot water, steam, or a hot inert gas.
