REMOVING CONTAMINANTS FROM SYNTHESIS GAS

A process of removing contaminants such as ammonia from synthesis gas obtained from partially oxidizing in a gasification reactor (2) a carbonaceous feed (1) comprising the steps of scrubbing (18) the synthesis gas with water (20) to obtain a first ammonia-containing aqueous stream (22) and a partly...

Beschreibung
Zusammenfassung:	A process of removing contaminants such as ammonia from synthesis gas obtained from partially oxidizing in a gasification reactor (2) a carbonaceous feed (1) comprising the steps of scrubbing (18) the synthesis gas with water (20) to obtain a first ammonia-containing aqueous stream (22) and a partly treated synthesis gas (24); stripping (25) the first ammonia-containing aqueous stream (22) with steam (26) to obtain an ammonia-containing gaseous stream (30) and a treated aqueous stream (20); scrubbing the ammonia-containing gaseous stream (35) with water (37) to obtain a treated gaseous stream (38) and a second ammonia-containing aqueous stream (40); and supplying the second ammonia-containing aqueous stream (40) to the gasification reactor (2).
