Compared with the cryogenic separation technology, PSA-CO plant has quite a few advantages: simple operation, short start-up and shut-down time, flexible load adjustment and high automation. It only takes tens of minutes to start up. Meanwhile, according to the downstream needs, load adjustment within the range of 30% to 100% can be realized by simple adjusting at short notice, which can greatly save the cost during commissioning and pilot run of the plant, thus lowering the investment indirectly.

The pressure swing adsorption plant is made up by adsorption vessels, vacuum pumps, compressors, program-controlled valves, etc. The plant is simple and easy to operate, and common employees can master the operation by simple training. The supporting equipment can be purchased and manufactured domestically, which assures the safety of the plant. Also, installation is not difficult, and construction can be completed in a short time.

Considering the above advantages, PSA-CO technology is widely used in the treatment of coal chemical synthesis gases and various complex exhausts. It is applied to treat entrained-bed gas, water gas, semi-water gas, natural gas conversion gas, calcium carbide furnace exhaust, acetic acid tail gas and blast furnace exhaust for production of downstream chemical and industrial products such as acetic acid, butanol, TDI, ethylene glycol, etc.
