热水伴随系统(加热设备和管线)结垢,是一个具有普遍性的问题。经过反复试验筛选,找到了良好的防垢剂ATMP。该防垢剂属有机膦酸型,具有螯合性、吸附性、表面活性等,因此防垢效果较好。本文根据 ATMP 与六偏磷酸钠(无机聚磷酸盐型)对比试验的大量资料,分析了它们的阻垢率、热稳定性、缓蚀性以及这些性能与温度、时间、加药量和水质硬度等影响因素之问的关系;论述了 ATMP 的防垢机理,并以在大庆葡萄花油田三管热水伴随集输流程中的试验和应用效果,说明 ATMP 确是一种既经济而又有效的防垢剂,有推广应用价值。
Hot water with the system (heating equipment and pipelines) scaling, is a universal problem. After repeated trial screening, found a good scale inhibitor ATMP. The anti-scaling agent is an organic phosphonic acid type, with chelating, adsorption, surface activity, and so anti-scaling effect is better. In this paper, according to a large number of data of ATMP and sodium hexametaphosphate (inorganic polyphosphate type) comparative test, their scale inhibition rate, thermal stability, corrosion inhibition and their relationship with temperature, time, dosage and water hardness And other influencing factors; discusses ATMP anti-scaling mechanism, and in Daqing Putaohua oil field with three sets of hot water in the process of gathering and gathering the test results and application of that ATMP is indeed an economical and effective Anti-scaling agent, a promotional value.
