80年代中期以来，美国、日本、西欧等工业发达国家，相继兴起用变压吸附（PSA）技术制取高浓度氧的开发研究。新的PSA装置可以生产出氧浓度高达99％～99．8％（V／V）的氧气。1992年日本住友精化公司成功地利用PSA技术生产出氧浓度为99．5％的氧气，并使这种新的PSA装置商品化[
Since the mid-1980s, industrialized countries such as the United States, Japan, and Western Europe have successively developed the research and development of high concentration oxygen using pressure swing adsorption (PSA) technology. The new PSA unit can produce oxygen with an oxygen concentration of 99% to 99.8% (V/V). In 1992, Sumitomo Seiki Co., Ltd. successfully used PSA technology to produce oxygen with an oxygen concentration of 99.5%, and commercialized this new PSA device [
