Abstract: The high investment, high energy consumption for absorbent regeneration, and high operational costs of current chemical-based CO₂ capture systems pose major obstacles to their large-scale application. To recover the latent and sensible heat in the steam at the top of the stripper and facilitate the desorption reaction, a process simulation model for CO₂ capture using organic amines based on compression heat pump technology was established using Aspen plus software. This primarily explored the impact of stripper bottom pressure, rich solvent temperature entering the stripper organic working fluid vaporization rate, and process flow on the CO₂ regeneration process. The results demonstrate that the heating coefficient of the organic working fluid R123 is higher than that of R141b and R245fa. Specifically, its coefficient of performance （COP） reaches as high as 2.35, while its exhaust temperature is lower compared to R141b and R245fa. Additionally, the exhaust temperature of R123 is lower compared to that of R141b and R245fa. The compression-type heat pump employs R123 as the circulating process medium, and the heat recovered by the heat pump is utilized to heat the post-heat-exchange rich solution in the lean/rich solution heat exchanger, thereby reducing the energy consumption for the regeneration of the absorbent solution. Considering the regeneration energy consumption of the desorption system, working fluid circulation volume, and desorption efficiency, injecting a 15% rich solvent ratio at the 12th stage position is deemed appropriate. The payback period for the heat recovery process using the heat pump is 0.82 years, demonstrating significant economic value.
