讲座摘要:
Process intensification (PI) has the potential to significantly reduce capital and operating costs in post-combustion CO2 capture using MEA solvent for power plants. The intensified absorber was modelled using Aspen Plus® rate-based model with modifications in mass transfer correlations using visual FORTRAN. The model for intensified absorber was validated using experimental data and showed good agreement. Process analysis carried out indicates: (a) CO2 capture level increases with higher rotating speed. (b) Higher lean MEA inlet temperature leads to higher CO2 capture level. (c) Increase in lean MEA concentration results in increase in CO2 capture level. (d) Temperature bulge is not present in intensified absorber. Compared with conventional absorber using packed columns, the insights obtained from this study are (1) Intensified absorber using rotating packed bed (RPB) improves mass transfer significantly. (2) Higher flue gas temperature or lean MEA temperature will not be detrimental to the reactive separation as such cooling duty for flue gas can be saved. (3) Inter-cooling cost will not be incurred since there is no temperature bulge. These insights can be useful for design and operation of intensified absorber for CO2 capture.
