摘要
引进的四川石油管理局川东天然气净化厂,因原料气H_2S含量下降,CO_2含量上升,面临直通法硫回收装置难以运行、全厂蒸气无法平衡等问题。作者提出将1200单元改为MDEA-环丁砜溶液,1500单元改为MDEA水溶液等对策,不仅可以克服上述困难,并可获得重大经济效益。本文还讨论了更换溶液的实施方案,提出了一些可供选择研究开发的新课题。
The East Sichuan Natural Gas Purification Plant introduced by Sichuan Petroleum Adminis tration has faced the problems, such as the difficulties operating the sulfur recoverying equipment by straight-through method, and not equibrating the steam in all the plant, etc., because the content of H_2S decreases and thatof CO_2 increases in raw gas. The authors present the countermeasures on changing 1200 th unit into MEDA-Sulfonol solution, and 1500 th unit into MEDA aqueous solution, which not only overcome the difficalties mentioned above but also obtain marked economic benefit. The implemention scheme of solution-changing is dicussed in this paper also. Some new subjects for selecting, researching and developing are presented.
