Abstract: This is an apparatus for continuously separating a liquid mixture comprising particulate carbon produced by the partial oxidation of a hydrocarbonaceous fuel, water, and liquid organic extractant into two separate immiscible streams i.e. a stream of particulate carbon-liquid organic extractant dispersion and a separate stream of clarified water. The subject apparatus may be referred to as a carbon decanter and comprises a closed pressure vessel whose horizontal cross-section is circular. Thus, the decanter may be shaped like a vertical cylinder or may be spherical shaped with discharge ports in the top and bottom.
