Abstract
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.
