Depending on the upstream and downstream or product quality indicators, the degree of CO2 retained in the decarbonized gas is different. For example, GB17820-2018 "Natural Gas" requires that the CO2 content in Class I natural gas be less than 3%, and the CO2 content in Class II natural gas be less than 4%.

In addition, the current regeneration circulation device of the decarbonization solution has cumbersome procedures and poor use effect. Therefore, a regeneration circulation device for the decarbonization solution that absorbs carbon dioxide is needed. Utility Model Content
