Abstract:

The application and adjustment of ZH471,a corrosion and scale inhibitor, to the circulating water system in Jiujiang Fertilizer Plant,Jiujiang Branch,SINOPEC is introduced. Quantitative analysis and evaluation of its performance are made. Aiming at the problems existing in operation and for the sake of preventing the heat exchanger water sides from corrosion and scaling under the condition of high concentration,it is adopted to combine static state rotary plates with dynamic simulated tests. Further selection and optimization are carried out to the prescription of ZH471. It is evaluated that ZH471,as a water treatment agent,is a kind of organic phosphine compound having excellent efficiency to inhibit corrosion and scaling,and resulting in obvious benefit economically.

Key words: circulating water, cycle of concentration, corrosion and scaling inhibitor

摘要：

介绍了ZH471阻垢缓蚀剂在九江分公司化肥厂循环水系统应用与调整情况, 就其阻垢缓蚀性能进行了定量分析与评价。针对系统运行中存在的问题, 以及为了防止在高浓缩倍数条件下换热器水侧腐蚀与结垢的产生, 采用静态旋转挂片与动态模拟试验相结合的方法, 对配方作了进一步的筛选与优化, 评选出ZH474水处理剂———一种高效全有机磷复合配方。实际运行表明该配方具有优异的阻垢缓蚀性能, 产生了较明显的经济效益。
