Discussion on Improving Catalyst Recovery in PTA Production System
In order to improve the catalyst recovery efficiency,the precipitation agent,precipitation pH val-ue and agitator speed were explored,combined with the concentration of catalyst recovery in wastewater,the process parameters of the catalyst recovery device in the best effect were analyzed.The process parameters of catalyst recovery were optimized to ensure the recovery rate of catalyst,reduce the catalyst content in sew-age,reduce the pressure of sewage treatment,reduce the use of fresh catalysts,and ensure product quality stability.
