Abstract:

The fifth recirculating cooling water system of Sichuan Petrochemical Company served as an oil refining circulating water system. The non-phosphorus program was selected for cooling water treatment according to supplementary water quality and system characteristics. Under the condition that the utilization rate of recycled water in the system reached 30%-40%, and the concentration ratio of daily operation was controlled at 4-5 times, the non-phosphorus water treatment program can achieve good anti-corrosion, scale inhibition, microbial control effects and timely disposed the emergency treatment such as oil leakage. The non-phosphorus program had ensured long period and stable operation of all process units, and got good economic and social environmental benefits.

Key words: refinery, recirculating cooling water, non-phosphorus, water-saving
