Pressure swing adsorption decarbonization technology

Thread Content

In addition to the devices mentioned above, there are several other units in China that are currently in operation using this full purge process: the pressure swing adsorption decarburization unit at Hubei Zhijiang Sanning Chemical Co., Ltd., which processes 30,000 NM3/h of shift gas to produce liquid ammonia; the pressure swing adsorption decarburization unit at Liaoning Fengcheng Fertilizer Factory, which handles 21,000 NM3/h of shift gas for the production of liquid ammonia; and the pressure swing adsorption decarburization unit at Hunan Anxiang Fertilizer Factory, which processes 1,500 NM3/h of shift gas for liquid ammonia production. Among these, the units with an annual production capacity of over 160,000 tons include the pressure swing adsorption decarburization unit at Inner Mongolia Wulasan Fertilizer Factory, which processes 96,000 NM3/h of shift gas, and the pressure swing adsorption decarburization unit at Hunan Dangyang Huahua Chemical Co., Ltd., which handles 88,000 NM3/h of shift gas
