The full purging process of pressure swing adsorption process has been started by the enterprise.
In addition to the above-mentioned devices, at present, many domestic devices have been put into operation by this full purging process: 30000 nm3/h pressure swing adsorption decarbonization device (producing liquid ammonia) for treating shift gas in Hubei Zhijiang Sanning Chemical Co., Ltd., and 2 1000 nm3/h pressure swing adsorption decarbonization device for producing liquid ammonia in Liaoning Fengcheng Chemical Fertilizer Plant. Hunan Anxiang Fertilizer Plant has entered the shift gas 1500NM3/H pressure swing adsorption decarbonization unit (producing liquid ammonia), among which the units with annual output of160,000 t are: 96,000 nm3/h shift gas pressure swing adsorption decarbonization unit of Wulashan Fertilizer Plant in Inner Mongolia, and 88,000 nm3/h shift gas pressure swing adsorption decarbonization unit of Hunan Dangyang Huaqiang Chemical Co., Ltd. to purify the carbon dioxide content in the gas.
