A106 部分酸化法ガス製造におけるガス精製技術の検討

抄録

This paper describes the technical issues of gas purification technologies for heavy oil IGCC and the study result to remove H2S and COS at the level of 20ppm total sulfur compounds as well as HCN at the level of 1ppm. The result shows the following three conclusions; (1) Chemical H2S absorption process (MDEA) is more economical than Physical absorption process. (2) The COS and HCN simultaneous hydrolysis catalyst shall be integrated with MDEA process. (3) The thermal amine reclaiming system is practical for MDEA process to remove HSS and thermal degradation of MDEA.
