A new publication from the Carbon Capture group at the University of Edinburgh is now available in "International Journal of Greenhouse Gas Control".
In this new study Dr Hyungwoong Ahn and collaborators present a detailed evaluation of ten different configurations of amine capture processes using 30 wt% aqueous monoethanolamine (MEA) solvent to capture 90% CO2 from an exemplary sub-critical pulverized coal-fired boiler power plant. Several new process configurations are presented with higher efficiency of the amine capture processes, resulting in a reduced heat duty in the reboiler. The new configurations are compared with known configurations from literature and patents using detailed process flowsheet simulations in Honeywell’s UniSim process simulator. The performance of the different processes are compared with respect to total energy consumption, including thermal and electrical energy used.
