Foaming behaviour of an aqueous solution of n-methyldiethanolamine (mdea) and aqueous solution of piperazine (pz)-n-methyldiethanolamine (mdea) for the carbon dioxide removal

This work focuses on one of the severe problem arise by the usage of amine in the removal of acid gases namely carbon dioxide (CO2) which is foaming. Foaming can cause reduction integrity of plant operation, excessive loss of absorption solvents, premature flooding, reduction in plant throughput, of...
