摘要
Abstract
Chemical absorption using alcohol amine solution as an absorbent is currently the most widely used technology in the field of natural gas decarbonization,with advantages such as large processing capacity and good cycle stability.However,the regeneration process of chemical absorbent consumes a lot of energy.To reduce the energy consumption of chemical absorption decarbonization,a natural gas chemical absorption decarbonization high-temperature heat pump coupling process is proposed.Through the high-temperature heat pump,the waste heat from the wastewater in the gas field is used for the regeneration process of the decarbonization process,achieving energy conservation and carbon reduction.Modeling and parameter optimization of the decarbonization system using MDEA solution was carried out using Aspen HYSYS software.The results showed that the decarbonization rate of the optimized process was as high as 95%,and the unit comprehensive power consumption of the system was 0.3821 kW·h/kg CO2,which was 56.72%lower than the conventional decarbonization system(unit comprehensive power consumption of 0.8828kW·h/kg CO2).关键词
