Abstract
The particulate carbon in a liquid organic extractant-carbon-water dispersion stream that is produced in a decanter is separated as clean, dry carbon particles from the liquid carrier by atomizing the dispersion and vaporizing the liquid organic extractant and water in a spray dryer. Thermal energy for completely vaporizing the liquid carrier is provided by directly contacting the atomized dispersion in the spray dryer with a split stream of hot raw synthesis gas containing entrained particulate carbon from a partial oxidation gas generator. The continuous closed-cycle operation permits recovery and recycle of the water used for cooling and cleaning the stream of raw synthesis gas as well as the recovery and reuse of the liquid organic extractant. Clean dewatered and clean saturated streams of synthesis gas are simultaneously produced along with the by-product clean, dry carbon particles.
