Abstract: A method and system for producing synthesis gas comprising CO, CO2, and H2 from a carbonaceous stream using an oxygen containing stream. A stream containing a carbonaceous material, and a stream containing oxygen are injected into a gasification reactor, where the carbonaceous stream is partially oxidised to obtain a raw synthesis gas. The raw synthesis gas is removed from the gasification reactor and directed into a quenching section wherein a liquid, preferably water, is injected in the form of a mist.

Abstract: The present invention relates to a process for the purification of raw syngas comprising the steps of (a) contacting the raw syngas with water to remove soot, resulting in a soot-rich waste water and a soot-lean syngas; (b) cooling the soot-lean syngas resulting from step (a) to a temperature in the range of from (20) to (50)° C.; and (c) contacting the cooled soot-lean syngas resulting from step (b) with water to remove HCN and NH3 resulting in clean syngas and HCN/NH3-rich waste water, wherein: (i) in step (a) the raw syngas is cooled below its dew point by its contact with water; (ii) the HCN/NH3-rich waste water resulting from step (c) is passed through at least one stripping column resulting in a clean water stream and a waste stream; and (iii) at least 50% (v/v) part of the clean water stream is recycled to step (c).
