Abstract
1300887 Materials for coking TEXACO DEVELOPMENT CORP 15 June 1971 [15 June 1970] 27861/71 Heading C5F [Also in Division C1] A process for treating sewage and municipal refuse comprises forming a sewage sludge, forming a slurry of municipal refuse with water derived from a subsequent coking step, separating heavy materials from the slurry with the aid of a gas which causes flotation of organic particulates, mixing the slurry with the sewage sludge, and coking the mixture under a pressure sufficient to prevent the vaporization of water, to form gas, grease, water of reduced BOD and coke. In one embodiment sewage which has been screened and comminuted is passed through a primary settler to form a primary sludge, an activated sludge chamber and a secondary settler to form a secondary sludge, part of which is mixed with the primary sludge and part returned to the activated sludge chamber. Municipal refuse which has been shredded, slurried with water is passed to a settler where with the aid of carbon dioxide or air, glass and metal are separated. The refuse slurry is then mixed with the sludge mixture and the resultant mixture is heated (e.g. 400-750F.) under pressure (e.g. 250-2400 p.s.i.g.) in a tubular reactor. The heated mixture is passed to a chamber where gas and grease are separated from the water and coke which are subsequently separated e.g. in a filter or cyclone. Part of the water is used in forming the refuse slurry and part mixed with the effluent entering the activated sludge chamber.
