原油加工专业词汇? Atmospheric crude oil distillation units , commonly known as atmospheric pipestills (APS) receive crude oil feed and separate it into fractions of different boiling ranges. The areas of particular interest of an APS unit are preheat train , furnace, pipestill tower and overhead system. Pipestill tower fractionates crude charge into up to seven cuts – overhead , five sidestreams , and bottoms in conventional distillation columns. For stripping live steam is injected. Overhead system condenses a naphtha stream, part of which goes to product and part of which is used for reflux. A typical overhead system has upward of 8 shell and tube exchangers or airfin condensers. 这段话专业词汇太多了,看不懂,很头疼,请大家帮帮忙解释解释。 Atmospheric crude oil distillation units是常减压蒸馏装置的意思吗?atmospheric pipestills 是什么意思?尤其是pipestill?train在这里是什么意思?airfin……查看更多11个回答 . 5人已关注
