There are a number of commercial coal gasification projects under design in the USA. By 1976-77, two such projects may be coming onstream in New Mexico, each producing 250 million standard cubic feet per day of Substitute Natural Gas (SNG). The gasification of coal produces large amounts of by-product phenol. The New Mexico projects will each involve about 25,000 tons per day of coal and will each produce about 100 tons per day of phenols. The gasification process uses steam, as a source of hydrogen, to produce methane from coal carbon. The by-product phenols are removed from the process by the condensation of excess steam. The phenolic steam condensate also contains ammonia and hydrogen sulfide. The bulk extraction of phenols from the gas liquor will be accomplished by using the Phenosolvan liquid-liquid extraction process offered by Lurgi of Germany. A process description and over-view are provided of the Phenosolvan process as applied to the recovery of 100 tons/day of by-product phenol, and the removal of ammonia and hydrogen sulfide, from the gas liquor effluent in a coal gasification plant designed to produce 250 MM SCFD of SNG from 25,000 tons/day of coal.
