Development of a hot gas cleanup system for integrated coal gasification/molten carbonate fuel cell power plants: Final report for the period October 1982-January 1985
This report summarizes work conducted by the Institute of Gas Technology on a conceptual gas cleanup system for removing sulfur-containing compounds and HC1 from coal-derived fuel gases at temperatures greater than 1000/sup 0/F. The gas cleanup system under investigation consists of two separate processes. In one process known as the IGT mixed metal oxide process, a fixed bed of metal oxide-containing sorbents removes the sulfur-containing compounds by reaction. The sulfided sorbent is then regenerated with an oxygen-containing gas to produce elemental sulfur. In the other process, a fixed bed of molten carbonate-containing sorbent removes the HCl by reaction. The spent sorbent from this process is either disposed of or reprocessed externally. Both experimental testing and preliminary cost projections have been conducted for the two processes. The experimental testing phase of this program has included laboratory-scale testing of potentially useful sorbents for both processes and larger-scale testing of superior sorbents under simulated process conditions. The preliminary cost projection phase has included the evaluation of several different regeneration schemes for the high-temperature fuel gas desulfurization process and an estimation of the cost of using the molten carbonate sorbent for HCl removal.
