Abstract: A complete set of electrochemical treatment technology for circulating water system has been developed cooperatively by CNOOC Ningbo Daxie Petrochemical Co.,Ltd. and CenerTech Tianjin Chemical Research and Des-ign Institute Co.,Ltd.,and its industrial application to the 4 000 m3/h Circulating Water Reservoir of Daxie Petroch-emical Co.,Ltd. accomplished. After the technology has been put into use,the operation of high-concentration rate(≥ 6.0) of the circulating water system is achieved,the rate of make-up water is decreased by 0.54%,and 199,000 tons of fresh water saved annually. At the same time,the dosages of chemicals,such as corrosion inhibitors,scale inhibitors,bactericides,etc. are decreased. The direct profits per year is more than RMB ￥1,000,000.
