A syngas treatment plant is configured to remove sulfurous compounds and carbon dioxide from shifted or un-shifted syngas in a configuration having a decarbonization section and a desulfurization section. Most preferably, the solvent in the decarbonization section is regenerated and cooled by flashing, while the solvent is regenerated in the desulfurization section via stripping using external heat, and it is still further preferred that carbonylsulfide is removed in the desulfurization section via hydrolysis, and that the so produced hydrogen sulfide is removed in a downstream absorber.
La présente invention concerne une installation de traitement de gaz de synthèse configurée de manière à retirer les composés sulfureux et le dioxyde de carbone de gaz synthétiques déplacés ou non dans une configuration comportant une section de décarbonisation et une section de désulfuration. Idéalement, le solvant dans la section de décarbonisation est régénéré et refroidi par flashing, alors que le solvant est régénéré dans la section de désulfuration via un stripage utilisant la chaleur externe, et, mieux encore, le sulfure de carbonyle est retiré dans la section de désulfuration via une hydrolyse, et le sulfure d'hydrogène ainsi produit est retiré dans un absorbeur en aval.
