摘　　要：介绍了多氨基多醚基亚甲基膦酸(PAPEMP)处理方案与膦酸盐/锌盐处理方案在乙烯生产循环冷却水处理中的动态试验。在乙烯生产装置循环水系统,使用PAPEMP处理方案代替膦酸盐/锌盐处理方案,在热负荷增加及高浓缩倍数等苛刻条件下系统腐蚀和结垢控制良好。PAPEMP方案减少循环水系统的清洗次数,满足了乙烯装置长周期稳定运行的要求。Dynamic simulation test using polyamino polyether methylene phosphonate （PAPEMP） scheme and phosphonate zinc scheme in recirculated cooling water treatment system for ethylene production were introduced. In ethylene plant cooling water system, PAPEMP treatment scheme substitutes for phosphonate zinc treatment scheme, which can obtain satisfactory corrosion protection and scale control under condition of heat transfer quantity and concentration ratio improved. The PAPEMP treatment scheme reduces chemical cleaning of recirculated cooling water system, which means the ethylene equipment can operate chronically and stably.
