The process configurations are compared with respect to total energy consumption, including thermal and electrical energy used. The comparison includes known configurations available in the literature and in patents. Additional configurations which lead to improved amine capture processes are presented, which result in further reduction in the reboiler heat duty. The use of detailed process ...
01/08/2013· We proposed a new concept of amine process design having multiple strategies applied where the heat duty in the stripper is as low as around 2.22 MJ/kg CO 2 which can be significant reduction considering that in conventional process (3.52 MJ/kg CO 2) and an overall energy penalty of only 8.1%, compared to 9.0% of the conventional amine absorber and stripper configuration.
