上世纪70年代初,四川天一科技股份有限公司(原西南化工研究设计院)在国内率先开展变压吸附(PSA)技术研究,80年代实现工业化后,PSA技术得到快速发展。天科股份在镇海炼化60000Nm3/h PSA制氢国际招标中标后,结束了国外装置在国内的垄断,现在单套PSA提氢装置的规模可达300000Nm3/h。同时PSA技术应用范围不断扩展,在石化行业的重整气、催化干气、变换气提纯氢气,催化干气回收乙烯,聚烯烃尾气中回收烯烃等领域实现工业化。
The early 70s of last century, Sichuan Tianyi Science and Technology Co., Ltd. (formerly Southwest Chemical Research and Design Institute) in the country took the lead in pressure swing adsorption (PSA) technology research, industrialization in the 1980s, PSA technology has been rapid development. Tianke shares in the Zhenhai Refining and Chemical 60000Nm3 / h PSA tender international bidding after the end of the monopoly of foreign installations in the country, and now a single PSA scale of hydrogen up to 300000Nm3 / h. At the same time PSA technology applications continue to expand, in the petrochemical industry reformer gas, catalytic dry gas, shift gas purification of hydrogen, catalytic dry gas recovery of ethylene, olefin polyolefin gas recovery and other fields to achieve industrialization.
