摘要： 为了解决珠海天然气发电有限公司海水循环水的结垢问题，分别进行了静态阻垢试验、杀菌灭藻剂和海生物杀生剂对阻垢性能影响试验、动态模拟试验、RO浓水对阻垢性能影响试验等，研究了海水阻垢分散剂 TS-636的阻垢性能。结果表明，按补充水量计，TS-636质量浓度为10～12 mg/L时，自然浓缩至3.0～3.5倍，污垢黏附速率<8.5 mg/（cm²·月），污垢热阻<1.0×10^-4 m²·K/W，能满足循环水浓缩倍数控制在2.0～2.5的要求。

Abstract: In order to solve the scaling problem in seawater circulating system of CNOOC Zhuhai Natural Gas Power Co., Ltd., a series of experiments, such as the static scale inhibition, the impact of biocide and marine creature biocide on the capacity of scale inhibition, the dynamic simulation and the impact of RO concentrated water on the capacity of scale inhibition etc. have been carried out. The capacity of TS-636 seawater scale inhibition dispersing agent has been studied during those experiments. The results show that according to the quantity of make-up water, when the mass concentratiobn of TS-636 added is controlled at 10-12 mg/L and concentrated naturally to 3.0 to 3.5 times, the fouling adhesion rate could be less than 8.5 mg/(cm²·month), and fouling resistance less than 1.0×10^-4 m²·K/W, which could meet the requirements that the circulating water concentration multiple should be controlled between 2.0 to 2.5 times.

Key words: seawater circulating water, scale inhibition dispersing agent, scale inhibition capacity, concentration multiple
