Hydrogen is increasingly demanded in various fields,including fuel cells,semiconductor processing,and the petrochemical industry.When steam reforming technology has been applied to produce hydrogen,it is very important to remove other impurities (mainly CO,CO2 and CH4) using adsorption separation technology,which is generally considered to be low in energy consumption and very precise in H2 separation (99.99%) with the aid of pore size and surface characteristics of adsorbent.Pressure swing adsorption (PSA) has been extensively used in the industry to obtain the desired product by separation and purification [1].

近年来,尽管甲醇合成催化剂的研发在不断进步,其活性逐渐增加,甲醇合成塔的结构也在不断改进,但是,在甲醇实际的生产过程中,甲醇合成中CO和C02的单程转化率还是远远小于平衡转化率.为了进一步提高CO和C02的转化率和合成过程的推动力,甲醇分离技术的改进已经成为了必然,低压甲醇分离装置的作用就是抛开了常规思维中的仅仅考虑液态甲醇的分离效果,更着眼于液态、气态甲醇的进一步分离和回收.在经济效益、节能降耗
