Abstract

Acid gas removal from syngas is an important process step upstream of its further processing for combustion or further processing of syngas. Integrated Gasification Combined Cycle (IGCC) power plant or chemical production (such as urea or petrochemicals, etc.). The process of absorbing the H2S in Di-Methyl-Ethre of poly-Ethylene-Glycol (DMEPEG) solvent and the process of enriching the DMEPEG solvent with dissolved H2S has been described in literature (including the publications by the Author). This publication describe the process of stripping out the dissolved H2S from the DMEPEG solvent using a thermal stripper designed using the rate based mass transfer simulations carried out using ProTreat software.
Basic process design and equipment size is described in this publication. 20 MW heat input is needed to strip out 19.13 kmol/s H2S from the 1.136 kmol/s DMEPEG solvent thus resulting in overall heat consumption of 30.7 GJ / Ton H2S capture.
Limitations of this process design are also described. Various options of packed tower configuration have been suggested for tower internals resulting in similar performance.
