PY34-1气田乙二醇回收系统在国内自营气田的应用属首例,其脱二价盐是最复杂的单元,原工艺设计在现场应用存在诸多值得优化和改进的地方.为了解决影响脱二价盐单元正常运行的问题,现场采取了参数优化、逻辑修改、流程和罐体改造等措施.通过优化改造,脱二价盐单元能够按照逻辑程序顺利运行,生产清洁度达标产品;同时不再影响再生单元的正常生产,消除了影响台风模式生产的因素,为以后的操作和技术发展积累了经验,为乙二醇回收系统国产化研究奠定了理论基础.%It's the first application for mono-ethylene glycol recovery unit (MRU) of Pa-nyu34-1 gas field in the domestic self-support gas field. Divalent salt removal is the most complicated process in the system and there are many worth of improvements for its original design. In order to solve the problems affecting the divalent salt removal unit's normal run-ning, the gas field took measures like parameter optimization, logic change, process and tanks reconstruction and so on.Due to the measures,divalent salt removal unit can run nor-mally as per PLC logic, make the products'cleanliness qualified. Meanwhile the regenera-tion system could not disturb the normal operation and the factors which influence the ty-phoon mode operation were eliminated. The reconstruction accumulates the experience for prospective operation and technology development,laid a theoretical basis for MRU study in the domestic.
