Abstract
Greenhouse effect main reason for the significant increase in global average temperatures since the industrial revolution. Greenhouse effect is most likely one of the reasons for the extensive use of fossil fuels so that the CO2 concentration in the atmosphere increased significantly. In order to suppress the rise in CO2 concentration, Energy saving and carbon reduction have become the key projects of the National Energy Policy Development Environment. For this purpose, we build a carbon capture system in steel plant and laboratory. As a basis for the application of various absorbents related research, and provide process improvement methods to achieve energy savings. The study capture CO2 by 30wt% MEA solution and 4mPZ+4mDETA solution that was carried out in rotating packed bed connected gas stripper. The conventional packed bed absorber and stripper were replaced by a rotating packed bed for reducing the volumes of conventional packed bed absorber and stripper and the regeneration energy of chemical absorbent in CO2 capture process. Developed as a result of gravity rotating bed can improve the gas-liquid contact surface area. In the study, compared with conventional packed bed and rotating packed bed for CO2 capture efficiency at same fixed operation condition. It was found that both capture efficiency are similar, but the volume of rotating bed is the volume of the conventional packed bed 1/3 times.
