摘要:为了研究LNG工厂停产状态下循环冷却系统特性,找到冷态运行经济与环保共赢方案,结合LNG工厂停产情况下循环系统各项控制实例,通过添加更换药剂、优化循环水流量,控制循环水泵电耗,制定方案。研究表明:浓缩倍数是水质处理的关键因素。高浓缩倍数状态时,药剂在水中的停留时间更长,应选用稳定性优良、不易分解的药剂。若浓缩倍数发生大幅降低则必须立印调整药剂用量及种类,同时循环水泵流量控制必须与药剂控制复合使用。pH值调节对水质处理有辅助作用,后续可对此开展节能措施研究。具体可通过pH调节、药剂调节与流量调节协同配合的方式达到最好水质处理效果,取得最大经济效应。

Abstract: In order to study the characteristics of cireulating cooling system of LNG plant under shutdown state and find out win-win solution between economy and environmental protection for cold-operation, combined with the control cases of circulating system in LNG plant during shut down, plan has been made by adding and changing chemicals, optimizing circulating water flow, controlling circulating water pump power consumption, Research shows that concentration ratio is a key factor in water treatment. With high concentration ratio, chemicals will stay longer in the water. Persistent chemicals with good
