Fluidized-Bed Reactor and Hot Gas Cleanup Facility
As part of the Morgantown Energy Technology Center`s (METC) Advanced Gasification and Hot Gas Cleanup Facility, a 907 kg (1 ton) coal-per-day (10-inch inside diameter) jetting fluidized-bed gasifier provides realistic fuel gas for testing and developing high-temperature, high-pressure components and processes in a reducing (gasification) and oxidizing (combustion) environment. Operated mainly as a gasifier, the 0.25-m (10-inch) diameter reactor produces up to 227 kg/hr (500 lb/hr) of coal gas at 866 K (1,100{degrees}F) and 30 atmospheres (425 psig) for downstream testing. The raw coal gas is sampled for major and trace species and sent to a filter vessel capable of operating at 894 K (1,150{degrees}F) and 20 atmospheres (290 psig) of pressure. After particulate removal, the gas can be independently controlled to up to five sampling or reaction vessels including fluid-bed desulfurization, transport desulfurization, chloride, alkali, or other contaminant removal or recovery processes. The fluid-bed desulfurizer is capable of being isolated, purged, and exposed to an oxidizing environment for sorbent regeneration or other oxidation reaction. Isokinetic hazardous air pollutant (HAPS) monitoring is provided at the upstream and downstream of particulate removal. Over the post three years, 1,200 hours of operation have been completed in support of six separate Cooperative Research and Development Agreements (CRADAs). These research agreements have been in the areas of candle filters and materials testing, direct sulfur recovery from sorbent regeneration tail gases, and gasifier development.
