Abstract—This paper discusses about possible configurations to improve the process with reduction of re-boiler energy demand. The simulations are performed in the Aspen Plus process simulation tool to check the required re-boiler duty. In the new model configuration, the rich solvent to the stripper is split using splitter block and supplied to the stripper section. The re-boiler duty for 85%, 90% and 95% removal efficiency cases are calculated for new model configuration and it is 3255, 3360 and 3614 kJ/kg CO2 respectively. This is around 10% reduction of re-boiler duty compare to the conventional process.
Index Terms—Carbon capture, model configuration, post combustion, re-boiler duty.
