《中国冶金报》2003年4月9日报道,2003年3月20日,杭氧股份公司制造的江苏沙钢集团东方制气公司第二套21000m~3/h制氧机顺利调试出氧,目前氧气纯度已达99.6%,液面基本稳定。该制氧项目主要设备空压机从国外引进,其中空分采用分子筛吸附、增压膨胀机流程、全精馏、无氢制氩新工艺,具有制氧能耗低、氧和氩提取率高、运行稳定安全、操作维修方便等特点。
On March 20, 2003, “China Metallurgical News” reported that on March 20, 2003, the second set of 21000m ~ 3 / h oxygen generator manufactured by Hangyang O & M Co., Ltd., Dongfang Gas Company of Jiangsu Shagang Group successfully commissioned oxygen. Currently, Oxygen purity has reached 99.6%, the liquid level is basically stable. The main equipment of the oxygen project is the introduction of air compressor air compressor, which uses molecular sieve adsorption air separation, booster expansion process, full distillation, hydrogen-free argon new technology, with low oxygen consumption, oxygen and argon extraction rate , Stable and safe operation, easy operation and maintenance and so on.
