| 英文摘要 | The present work explores how much IGCC can benefit from warm gas clean-up(WGCU)in comparison with conventional cold gas clean-up(CGCU) and what are the respective contributions of dry particulates removal and warm gas desulfurization (WGD) in a plant-wide point of view. Influences of key parameters of WGD on thermodynamic performance of IGCC plant including desulfurization temperature, oxygen concentration in the regeneration stream, and H2S removal efficiency are discussed. It is obtained that the net efficiency of IGCC with full WGCU experiences an improvement of 1.77 percentage points compared with IGCC with full CGCU. Of which, dry particulates removal without water scrubber contributes about 1 percentage point. The influence of desulfurization temperature on thermodynamic performance of IGCC with WGD is weak especially when it is higher than about 350A degrees C, which indicates that more focus should be put on investment cost, technical feasibility and sorbent stability for the selection of optimal operation temperature. Generally, 2%similar to 3% of oxygen concentration in the regeneration stream might be reasonable in a thermodynamic performance point of view. In addition, the improvement of 0.31 percentage points can be obtained by removal of H2S in the syngas from 27 ppm to 3 ppm. |
