Abstract: A method of producing syngas comprising receiving raw syngas from a gasification unit; introducing the raw syngas and water to a syngas scrubber to produce unshifted syngas; introducing a first portion of unshifted syngas to a first cooling unit to produce cooled unshifted syngas and a first aqueous condensate comprising cyanide in an amount of 5-200 ppmw; recycling the first aqueous condensate to the syngas scrubber; introducing a second portion of unshifted syngas to a water gas shift unit to produce shifted syngas; introducing the shifted syngas to a second cooling unit to produce cooled shifted syngas and a second aqueous condensate comprising cyanide in an amount of less than 2.5 ppmw; contacting the cooled shifted syngas with the cooled unshifted syngas to produce modified syngas; and introducing the second aqueous condensate to a sour water stripper to produce stripped water and an acid gas comprising H2S, CO2, and ammonia.
