请问一下这个怎么翻译－中冷油吸收技术？ 在乙烯的回收工艺中有一个“ 中冷油吸收技 术 ”和“从催化干气中提浓乙烯”，请问这个怎么翻译？谢谢 网上有篇论文是讲这个的，他译成cold oil absorption technology，但是查不到此种英文表述的其它出处。 摘要： 本文介绍了几种干气回收乙烯技术:干气生产乙苯技术,工艺比较简单,可以直接生产乙苯,但因催化干气中乙烯浓度较低,相对高纯度乙烯来说,其设备投资相对较大;深冷分离技术能耗高,装置投资大; 变压吸附 的主要缺点是难以通过一次分离得到聚合级乙烯,一般条件下得到的乙烯纯度为80%(体积分数),如采用配套组合工艺生产高纯度乙烯,投资相应增大; 中冷油吸收技术 ,只能生产84%(体积分数)粗乙烯;先进的回收系统技术,能耗低,比常规的深冷分离技术节能15%-25%,烃类回收率达到96%,对原料适应性强、产品纯度高,但该工艺为国外技术,涉及的专利费用较高。 this paper introduced some kinds of recovery technologies of ethylene from dry gas. the technology of making ethyl benzene from dry gas was more simple and could directly produce ethyl benzene. ethylene concentration in dry gas was low, so its equipment cost was higher comparing with high purity ethylene; the energy consumption and investment of deep cold separation technology were very high; the major shortcoming of pressure swing adsorption technology was too difficult to get qualified ethylene through on... 论文见 http:///onlineread/onlineread.asp?id=20428388 ，需要付费或注册方可下载。 查看更多
