Abstract: The effluent gas stream from a partial oxidation gas generator is scrubbed with water. A dispersion of particulate carbon and water is produced, mixed with a liquid organic extractant, and separated in a decanter. The overhead stream from the decanter, comprising a dispersion of carbon in the liquid organic extractant, together with small amounts of water, is mixed with extraction oil and heated in a vaporizing operation to produce a vaporized overhead mixture, comprising substantially all of the water and liquid organic extractant, and an unvaporized liquid bottoms dispersion of carbon in extraction oil containing only a minor amount of water and liquid organic extractant. The bottoms dispersion is passed into a steam stripper in counterflow with stripping steam.
