Selective Catalytic Oxidation of Hydrogen Sulfide--Systems Analysis for IGCC Applications
Selective catalytic oxidation of hydrogen sulfide (SCOHS) has been evaluated conceptually for IGCC applications, and the theoretical limits of reaction performance, process performance, and economic potential in IGCC have been estimated. Syngas conditions that have high partial pressures of total sulfur result in substantial liquid sulfur retention within the catalyst bed, with relatively complex processing being required. Applications that have much lower total sulfur partial pressure in the process gas might permit SCOHS operation under conditions where little liquid sulfur is retained in the catalyst, reducing the processing complexity and possibly improving the desulfurization performance. The results from our recent IGCC process evaluations using the SCOHS technology and conventional syngas cleaning are presented, and alternative SCOHS process configurations and applications that provide greater performance and cost potential are identified.
