Abstract

L'invention concerne un procédé et un appareil de production de gaz combustible propre non corrosif s'utilisant dans un processus de combustion. Ledit procédé consiste à traiter un flux de déchets provenant de la digestion de matières lignocellulosiques, en oxydant partiellement le flux de déchets afin de former des gaz chauds et des sels fondus, puis en faisant refroidir les gaz chauds et les sels fondus à l'aide d'une liqueur de trempe pour former un gaz trempé (76) et une liqueur carbonate (30). Des particules sont retirées du gaz trempé pour former un gaz combustible brut en soumettant le gaz trempé à un processus à phases multiples de réduction d'émanations (80), comprenant l'extraction de la chaleur (91) du gaz trempé afin de réduire la charge de particules et le contenu en eau du gaz trempé pour former un gaz combustible à faibles émanations. H2S est retiré du gaz combustible à faibles émanations à l'aide d'un processus de retrait de H2S (105) qui est plus sélectif pour H2S qu'il ne l'est pour CO2, la phase de retrait formant un gaz combustible propre non corrosif et des gaz acides.
