When the operating pressure of ammonia carbon monoxide decarburization in our plant is 1.38MPa, there is a problem that the CO2 removal capacity of the decarbonization equipment is beyond the standard of the purified gas and the capacity of the equipment can not be fully exerted. However, although the CO2 pressure of the high pressure decarbonization equipment is qualified, Device capacity is still limited, but also 2 kinds of pressure level equipment
