摘　　要：设计了一种碳分子筛(CMS)变压吸附制氧工艺.以碳分子筛为吸附剂,以富氧气体为原料气,基于PLC控制系统,建立变压吸附制氧工艺.由预处理单元、吸附单元、控制单元、动力及管路系统组成的变压吸附制氧工艺可对富氧气体中氧气进行分离.实验表明:所设计的基于PLC控制的CMS变压吸附制氧工艺,实现了变压吸附制氧工艺参数的在线监测、调整与优化,可提高产品气氧气的浓度,用于高纯氧的制备.The process for oxygen production by PSA using a carbon molecular sieve （CMS） is designed. The PSA oxygenprocess is established based on CMS as an adsorbent, oxygen-rich as a raw material gas and PLC control system.The oxygen process, including pre-processing unit, adsorption unit, control unit, power and pipeline systems,could separate oxygen out from the oxygen-enriched gas well. The oxygen generating process based on PSA usingCMS and the PLC control system could achieve the on-line monitoring and adjustment of PSA process parametersto improve the product gas concentration for the preparation of high purity oxygen.
