The main drawback of amine-based CO2 capture system is high heat requirement for the solvent regeneration.The optimization of the process parameters is an effective way to break this limitation.In this paper

the experiments are carried out to investigate the stripper performance under diverse parameters of regeneration process

including the effects of CO2 loading and feeding temperature of rich-solutions

reboiler temperature

regeneration pressure and alkanolamine type.The changes of sensible heat and heat of vaporization were analyzed.A rate-based model in Aspen Plus simulator was used to simulate the regeneration process.The results show that the heat requirement for the regeneration can be reduced by using higher CO2 loading and feeding temperature of rich-solutions

while the heat requirement for regeneration increased with increasing reboiler temperature and regeneration pressure.The regeneration heat of monoethanolamine(MEA)is quite high

and can be reduced by blending methyldiethanolamine(MDEA).The CO2 desorption rate increased with the CO2 loading of rich solution and reboiler temperature.
