Abstract

A syngas treatment plant has a decarbonization section and a desulfurization section that use the same solvent to remove various acid gases. Contemplated methods and plants are highly effective in removal of CO2, recycle sulfurous contaminants to extinction. Minimal loss of H2 while maximizing H2S concentration in a Claus plant feed during regeneration of the solvent is achieved by stripping the solvent with both treated syngas and a flash vapor of the desulfurization section.

Claims

AMENDED CLAIMS received by the International Bureau on 15 June 2012 (15.06.2012) What is claimed is:
1. Λ method of operating a syngas treatment plant, comprising:

Hashing the stripped rich solvent to thereby produce the Hash vapor;
further stripping the stripped rich solvent in a second stripper to thereby regenerate a lean solvent for use in the C02 absorber and to thereby produce a concentrated acid gas; and
feeding the dcsulfurized syngas into the C02 absorber to thereby produce the treated syngas and the CO2-loaded rich solvent.
2. The method of claim 1 further comprising a step regenerating a portion of the C02- loaded lean solvent in a plurality of flash steps, and using refrigeration content from the flash steps for refrigeration in the C02 absorber.
