循环水实施承包方案中出现的腐蚀和结垢问题

Corrosion and Scaling Problems During Implementing the Contract Scheme of Circulating Water in a Water Field

随着国内水处理技术的日益成熟和药剂的不断国产化,循环水处理药剂成本下降的空间较大。为此,中国石油某地区公司2015年通过公开招标的方式,对十一个循环水场实施循环水药剂总承包,实现降低循环水处理药剂成本的目的。某水场在总承包方案实施过程中出现了腐蚀率超标和换热器结垢的问题,通过重新招标,更新水处理方案,使水质恢复稳定。

With growing mature of the water treatment technologies and continuous localization of chemical drugs, the cost of circulating water treating agents fell greatly.Therefore,by open tendering, a regional company of Petro China determined a general supplier of chemicals for eleven circulating water fields in 2015,to reduce the cost of circulating water treating agents. During carrying out the general contracting program, the corrosion rate of one circulating water field overstepped and the heat exchanger fouled. By re-bidding, the water treatment scheme had been updated to restore water quality to stability.
