胺液在长期循环使用过程中均存在一定的热降解、化学降解和氧化降解,它们对溶液的脱硫效率、发泡倾向和腐蚀性均有很大影响。其中由于氧化降解产生的降解产物—热稳定盐(HSS)对设备腐蚀、溶液发泡等影响尤为严重,因此要保持天然气净化装置长周期稳定运行,必须要采取有效措施以保持溶液清洁。本文通过重庆天然气净化总厂引进美国MPR公司的胺液净化装置在四个分厂的应用情况,讨论了离子交换技术脱除胺液中的热稳定盐的应用效果,提出了运行过程中的一些问题和建议。 Amine liquid in the long-term cycle of the use of both the existence of a certain degree of thermal degradation, chemical degradation and oxidative degradation, their solution desulfurization efficiency, foaming tendency and corrosive have a great impact. Among them, heat-stable salt (HSS), which is a degradation product of oxidative degradation, has a serious impact on equipment corrosion and solution foaming. Therefore, in order to maintain the long-term operation of the natural gas purification device, effective measures must be taken to keep the solution clean. In this paper, Chongqing Natural Gas Purification Plant introduced the United States MPR company amine liquid purification plant in four branches of the application of ion exchange technology to discuss the removal of heat-stable salt in the application of the effect of ammonia in the operation of some of the proposed Questions and suggestions.
