摘　　要：大庆1200kt/a乙烯改扩建项目需配套建设1套丁二烯抽提装置。为了配合丁二烯抽提装置技术的选择,文中对目前最通用的3种丁二烯抽提工艺技术进行了对比分析。结果表明,N-甲基吡咯烷酮工艺技术的综合优势更为明显,推荐新建丁二烯抽提装置采用该技术。Daqing 1 200 kt/a Ethylene Revamp & Expansion Project needs to have a supporting butadiene extraction plant built. To help the selection of a butadiene extraction plant technology, the article made a comparison among the most commonly used 3 butadiene extraction process technologies. The result shows, the N-Methyl pyrrolidone process has a significant comprehensive advantage, and this technology is recommended for the to-be-built butadiene extraction plant.
