南京扬子石化公司烯烃厂与南京工业大学联合开发的变压吸附(PSA)回收乙二醇装置氧化反应系统排放气中乙烯技术,最近已通过了中国石化集团组织的专家鉴定。乙二醇装置的环氧乙烷排放气和催化裂化干气一般直接被燃烧,这些排放气中含有乙烯原料气,如此烧掉既浪费了宝贵的原料气,又 The PSA technology of ethylene glycol unit oxidation reaction system jointly developed by Nanjing Yangzi Petrochemical Company Olefin Plant and Nanjing University of Technology has recently passed the appraisal of experts organized by China Petrochemical Corporation. Ethylene glycol plant ethylene oxide emissions and catalytic cracking of dry gas is generally directly burned, the exhaust gas containing ethylene feed gas, so burned both waste valuable raw gas, and
