The coal gasification process being developed is based on work done at the Eyring Research Institute, Provo, Utah. Pulverized coal is fed to an entrained flow reactor where it is gasified by reaction with steam and oxygen. The ash in the coal may be removed as an inert slag and the product gas may be cleaned to remove sulfur-containing compounds and carbon dioxide to yield a clean fuel gas with a heating value near 300 Btu/standard cubic foot. To develop the process, construction and testing of an experimental unit, the PDU, is planned. Because of the developmental nature of the program, the PDU will contain only those components and features necessary to develop the gasifier and operate it safely. The PDU will be operated intermittently, with test durations ranging from a few hours up to a maximum of four weeks. During most of the testing the product gas will not be used but will be simply burned in a flare. During later tests the gas will be used in firing the brick kilns in the brick plant. Most of the testing will be done with a low-sulfur, Utah bituminous coal. Near the end of the planned effort, several tests, up to 100 hours each, will be made with alternate coals: a high-sulfur bituminous coal, a low-sulfur subbituminous coal, a lignite and a coal char or residue. Current effort on the program is directed toward design and specification of the PDU. Flow diagrams and material balances have been developed. A request for environmental permits has been prepared and submitted. Piping and instrument diagrams (P and ID's) and most of the equipment specifications have been prepared and reviewed.
