| 摘 要： | 由于整体煤气化联合循环（IGCC）发电本身的技术特点，使得其非常适合于进行燃烧前CO2捕集。针对IGCC特点，提出了一种MDEA脱酸气结合湿法氧化法硫回收的燃烧前CO2捕集流程。通过模拟计算，验证了流程的可行性。将其与IGCC发电系统集成，对比计算了有无燃烧前CO2捕集的IGCC系统供电效率等相关参数，燃烧前CO2捕集使IGCC供电效率降低约10个百分点。分析指出了导致包含燃烧前CO2捕集的IGCC供电效率降低的3个因素：蒸汽消耗、燃料化学能损失和新增动力设备电耗，并据此确定了今后的优化方向。

| Abstract: | Integrated gasification combined cycle (IGCC) power generation is an advanced and next generation coal-fired power generation technology, can provide clean and low-cost electricity for the users, and will play an important role in the future development of high-efficiency and zero-emissions power plants. CO2 capture technology before burning should be very suitable for IGCC system. Based on IGCC technical features, a CO2 capture process before burning, consisting of MDEA acid gas removal and wet oxidation sulfur recovery steps, is proposed in this paper. The feasibility study of application in IGCC system is verified by process simulation calculation. The results show that this process works well for acid gas removal, and the efficiency for separating CO2 and H2S from syngas can reach 99% and 98.5% respectively. However, the overall efficiency of power supply by IGCC, obtained by calculation, declines about 10 percent from 45.35% to 35.16%, when the CO2 capture process before burning is introduced into IGCC system. The three main factors of decrease of total efficiency are steam consumption, fuel chemical energy loss and new auxiliary power increase, and they could be used for determining optimization direction. |
