Abstract

Acid gas removal from syngas is an important process upstream of CO2capture in a pre-combustionIGCC power plant. Enrichment of previously absorbed H2S in DMEPEG solvent (by stripping out the CO2co-absorbed with H2S) is described in this publication. The unique capability of ProTreat software toconduct rate based mass transfer simulation is described and applied for H2S Enrichment simulation.Non-ionic liquid property model and its implementation in ProTreat software is described. Solubility ofCO2and H2S in DMEPEG solvent is described. Process condition for H2S Enrichment is justified in terms ofits integration within the overall IGCC power plant. Sensitivity study is conducted for various importantprocess parameters. systematic development and optimizations of H2S Enrichment process is describedconsidering optimization of techno-economic performance parameters. Interaction and integration ofH2S Enrichment with H2S absorption and H2S Stripper is analyzed. Performance and mass balance acrossH2S Enrichment is described. Limitations of this process design are also described. Various options aresuggested for tower internals resulting in similar performance. This kind of detailed process designis necessary for accurate detailed CAPEX assessment (by bottom-up approach) and techno-economic assessment.
