For a number of years the US Department of Energy's Morgantown Energy Technology Center (METC) has been involved in developing coal gasification processes to produce electricity from coal. Coal gasifiers produce raw synthesis gas at temperatures ranging from 700{degree} to 3,000{degree}F. Before these gases can be fed to a combustion gas turbine, hydrogen sulfide and particulates in the raw gas must be removed. To improve the efficiency of coal gasification processes, METC has been actively involved in the development of hot gas cleanup technologies for coal gasification processes. One of these technologies is the zinc ferrite process for hydrogen sulfide removal. The zinc ferrite process has been studied extensively at METC, and is now at the stage of demonstration testing. The objective of this study was to determine the cost of a zinc ferrite plant section within {plus minus}30 percent accuracy. The approach taken was to develop a detailed design for the zinc ferrite section for a given coal gasification plant and prepare a factored capital cost estimate for the section. Section 2.0 of this report describes the zinc ferrite process design and Section 3.0 presents the factored capital cost estimate for the section. The appendices include the section mass balance, an equipment list, major equipment specifications, and capital cost estimates. 1 ref.
