OSTI ID:6346718

The Gasification, Gas Treating, Compression, and Sulfur Recovery Areas constitute the Gas Systems Area of the SRC-I demonstration plant. The dust preparation unit receives the supplemental coal (if required) from the Coal Preparation Area, and the ash concentrate (KMAC) from the SRC Deashing Area. This unit is designed to provide the proper blend and particle size distribution for feeding the coal gasification unit. The GKT coal gasification process will be used to generate the required makeup hydrogen for the SRC Process Area and for the Expanded-Bed Hydrocracker Area from the KMAC/coal mixture. The wash water treatment unit is designed to remove the solid material (fly ash and slag) from the raw water used in the coal gasification unit for the various quenching, cooling, and washing steps. The raw syngas compression unit will be provided to boost the pressure of the raw syngas from the coal gasification unit. A shift unit will be designed to convert most of the carbon monoxide in the raw syngas to hydrogen. The Selexol process will be used to remove acid gases from the makeup hydrogen gas. A methanation unit will be provided to process a portion of the makeup hydrogen exiting the Selexol Unit for use in the Expanded-Bed Hydrocracker Area. The DEA process will be used to remove acid gases from the high pressure raw recycle hydrogen-rich gas (generated in the SRC Process Area and in the Expanded Bed Hydrocracker Area) and for treating the various low pressure raw fuel gas streams generated in the facility. The hydrogen compression unit will compress a portion of the treated makeup hydrogen stream from the Selexol unit, a portion of the treated hydrogen-rich from the DEA unit, and the recycle hydrogen stream from the hydrogen purification unit for use in the SRC Process Area.
