摘要

中石化安庆分公司腈纶厂循环冷却水系统的设计循环水量为16000m3/h,系统中热交换设备的材质主要是铜、不锈钢和碳钢,多数热交换设备为列管式换热器,少数热交换设备为夹套式换热器。根据循环冷却水水质和工况条件,对NJ-213阻垢缓蚀剂进行静态、旋转挂片和动态模拟试验及生产应用。试验和应用表明,在药剂质量浓度为40~60mg/L时,该药剂的阻垢率和挂片缓蚀率均达到了90%以上。

Abstract

Acrylic Fibre Plant of Anqing Branch of SINOPEC is a large scale chemical and fibre enterprise. Design amount of circulating cooling water is 16 000 m3/h in the circulating cooling water system. In the system the material of heat exchangers are mainly copper,stainless steel and carbon steel. A number of heat exchangers are the rank of heat exchanger, a few of heat exchangers are the jacket of heat exchangers.According to the quality and processing conditions of the circulating cooling water in the plant,NJ-213 static scale inhibition and corrosion inhibitor is estimated by the static scale inhibition tests,rotary coupon tests and dynamic simulated tests,and the industrial application. The tests and the application show that when the concentration of the chemicals are 40~60 mg/L,the proportion of scale inhibition rate and the corrosion inhibition rate of the test coupons are higher than 90%.
