Abstract

The development of a Fixed Bed Type Hot Gas Cleanup system for coal gasification combined cycle power plant had been newly succeeded with the achievement of 765 hours stable and continuous operation of the 20t / d pilot plant during March-April, 1995. This hot gas cleanup system, composed of the dust removal unit with a porous ceramic filter and the sulfur compounds(H2S, COS)removal unit with honeycomb desulfurizers enables highly efficient and stable performance under a wide range of gasifier operation. Moreover, in the sulfur recovery system, not only elemental sulfur but also gypsum was proved to be obtainable with high yield and purity. The Fixed Bed Type Hot Gas Cleanup Process is thus found to be suitable for the IGCC. In case of the fixed bed type, the scaling up for the demonstration plant is easy, since it can be designed with demensions proportional to the treated capacity.
