Design and Emission Reduction Capacity Analysis of Carbon Dioxide Process
The research and application of carbon dioxide capture technology are critical approach to mitigating the greenhouse effect.Depending on the different sequence of carbon capture and combustion processes,the primary technical pathways include pre-combustion capture,oxy-fuel combustion,and post-combustion capture.And post-combustion capture is the most technically mature and widely applied method.According to statistics,there are 573 carbon capture projects globally,and this number is increasing annually.It is estimated that the annual carbon dioxide capture capacity will reach 320.9 million tons by 2023.In this paper,the emission reduction capability of carbon capture process,includes synthesis gas desulfurization,CO shift reaction,shift gas desulfurization,CO2 capture and compression unit,is analyzed by using ASPEN HYSYS.The result indicates that the process can produce 339.4 t/h of carbon dioxide product.Compared to the original process,the integration of the new carbon capture process can reduce carbon dioxide emissions by approximately 265 t/h.
