Abstract:

Corrosion and scale inhibition efficiency of AEC water treatment program for the Yellow River water under conditions of 6 cycles of concentration has been studied by using the method of dynamic simulation test. The results show that, at water conductivity over 6000 μS/cm, calcium hardness(as CaCO₃) over 1200 mg/L and chloride over 1000 mg/L, the deposit rates of carbon steel and brass test tubes, and the corrosion rates of test tubes and coupons have all met the demands of National Petrochemical Industrial Company Standard. AEC program has excellent efficiency in corrosion and scale inhibition under the water conditions of high hardness, high alkalinity and high conductivity. When the cooling systems uses the Yellow River water as make up water, it runs safely and economically at high cycles of concentration.

Key words: Yellow River water, corrosion and scale inhibition, cycles of concentration

摘要：

通过动态模拟试验方法研究了AEC水处理方案在黄河水6倍浓缩倍数下的缓蚀阻垢效果。结果表明:在电导率超过6000μS/cm,钙硬度(以CaCO₃计)超过1200mg/L,氯根超过1000mg/L的水质条件下,碳钢和黄3铜试管的粘附速率及试管、挂片的腐蚀速率均达到了中石化标准的要求。AEC方案在高硬度、高碱度、高含盐量的水质条件下具有优良的缓蚀阻垢效果,对用黄河水作为补充水的冷却水系统,可在很高的浓缩倍数下安全经济地运行。
