Report of Visit to HYGAS Pilot Plant, Chicago, Illinois.
Enviro Control, Inc., Rockville, Maryland 1976 Nov:5 pages
A visit was made to the HYGAS Pilot facility located in Chicago, Illinois to inspect the coal gasification operation in progress at that site. This facility was operated on the hydrogasification concept and employed a unique system of staged gasification to maximize methane production within the reactor itself. All four gasification steps were completed within a single high pressure vessel. The facility was very clean. Several incipient fires were noted in the stock pile of Rosebud subituminous coal due to the drying out of the coal while it lay in storage. The use of a pay loader for coal loading was inherently a dirty operation. During operation coal was pretty widely scattered around the coal pit and loading bin up to the Williams mill. It seemed obvious that during the normal windy weather in Chicago, coal would most likely permeate the entire lower section of the facility. Strong hydrocarbon liquid vapor odors were noted in the control room and in the analytical section of the control room containing the on stream gas chromatograph units. A number of fire extinguishers were scattered throughout the site. No medical facilities were present. All personnel were issued shirts, pants, a jacket, safety helmet, and safety glasses. A voluntary medical examination program was in place.
