摘要: IGCC和CCS的结合是一种高效性和环保性的先进技术,基于IGCC的燃烧前CO2捕集技术越来越受到世界各国的广泛关注。介绍了中国首套燃烧前 CO2捕集系统的工艺流程,对其捕集能耗和成本做了分析。结果表明:该系统的捕集能力为9.46万t/年,捕集率大于88%,捕集CO2能耗为2.34 GJ/t,捕集成本为281.37元/t。同时指出了今后在降低蒸汽消耗方面的优化方向,该技术与常规电厂燃烧后CO2捕集技术相比,单位能耗与成本大幅度降低,是未来化石燃料实现低成本捕集CO2的关键技术。

Abstract: The IGCC-based pre-combustion CO2 capture technology, an efficient and environmental technology which combines the IGCC and CCS together, has attracted extensive attention all over the world. This paper introduces the process flow of the first pre-combustion CO2 capture system in China, and conducts the analysis on the energy consumption and cost of the capture. The results show that the capture capacity of the system is 94 600 tons/year with the capture rate over 88%. The unit energy consumption is 2.34 GJ/t, and the capture cost is 281.37 RMB/t. At the same time, the improvement direction for waste heat recycling and utilization is put forward. Compared with the conventional post-combustion CO2 capture technology , the energy consumption and cost of the capture are greatly reduced, which means that it may become the key low cost CO2 capture technology for fossil fuel combustion in the future.
