摘　　要：The implementation of carbon capture and storage in the petrochemical industry is one of the means of decarbonization.This research focuses on a comprehensive technical analysis of the deployment of post-combustion carbon capture and storage based on monoethanolamine absorption in the petrochemical industry.The olefin complex petrochemical industry in Tuban,Indonesia,is the basis for the analysis,which includes a steam cracker,polyethylene,polypropylene,and raw pyrolysis gasoline hydrotreating units,with capacities of 1000,940,600,and 570 kilotons/year,respectively.The total energy consumption is about 16024.53 GJ/h,and the CO_(2) emissions are about 1.6 megatons/year.Based on these plant systems,comprehensive technical analyses of the implementation of carbon capture and storage in that industry were performed using Aspen HYSYS®simulation software.Sensitivity analysis was carried out to determine the total CO_(2) captured,energy intensity,monoethanolamine consumption,and net CO_(2) captured in various scenarios based on the number of absorber column stages,absorption pressure,and desorption temperature.The CO_(2) storage site is about 100 km away and is transported by an onshore pipeline with a supercritical phase of CO_(2).The optimal net CO_(2) capture value is achieved by setting up a 50-stage absorber column with a pressure of 1 barg and a temperature of 110℃ at the top of the desorber column,resulting in a CO_(2) capture yield of 86.4%and an energy intensity of 12.6 GJ/ton CO_(2).Under these conditions,the net CO_(2) captured in the scenario based on gas power plants’electricity is 0.225 megatons/year,while in the scenario based on gas power plants incorporating 30%biomass electricity,it is 0.544 megatons/year.With increased use of renewable energy in carbon capture and storage facilities,more net CO_(2) is captured.This study can be applied to various cases of post-combustion carbon capture and storage implementation in the industrial sector,especially in the petrochemical industry.
