Regenerable and non-regenerable sorbents and process for acid gas removal

摘要

A dewatered ethanol residue regenerable and non-regenerable sorbent for the removal of acid gas from hydrocarbon production gas streams and the process for the removal of acid gas from hydrocarbon gas is provided. The process includes the steps of obtaining residue from the distillation of ethanol; de-watering the residue; mixing the de-watered residue with an amine; and, contacting the hydrocarbon gas with the dewatered residue/amine mixture.
