不停车清洗预膜技术在炼油循环冷却水系统的应用

Application of On-line Cleaning and Prefilming Technology in Refinery Circulating Cooling Water System

炼化企业装置较多,由于生产经营的需要,循环冷却水系统可能不能停工进行清洗预膜,导致水冷器的腐蚀、结垢问题。不停车清洗预膜可以实现在不停车的情况下在线进行清洗预膜,这样就可以控制系统的结垢和腐蚀问题。某炼油厂通过不停车清洗预膜的实施效果,考察了其可行性,并提出了一些建议。

Plants in refinery are various, due to the needs of production and operation, circulating cooling water system cannot be shut down for cleaning and prefilming, resulting in corrosion and fouling problems of the water cooler. The on-line cleaning and prefilming technology can realize the cleaning and prefilming of the circulating cooling water system without stopping, so that the scaling and corrosion of the circulating cooling water system can be controlled. The feasibility of the on-line cleaning and prefilming technology was investigated through using the on-line cleaning and prefilming technology in the circulating cooling water system of a refinery, and some suggestions were put forward.
