A effective way to clean the recirculating cooling water system on line and its effects

Since the decreasing heat exchanging efficiency of polymerizer,cleaning,prefilming and chemicals adding operation for recirculating cooling water system in the polymerization process were made without shutdown.The average corrosion rate of A3 steel and copper could reach 1.302 2 g/(m2·h) and about zero,respectively,a blue protection film was formed on the surface of A3 steel,and thus the foundation for the high-efficiency,safe and stable running of 70 m3 polymerizer was established.
