Process for removing contaminants from gas using polyethylene glycols

摘要

A process utilizing a solvent that includes dialkyl ethers of polyethylene glycols and water, contacting a product gas to remove gas contaminants from product gas streams. The solvent containing the dissolved gas contaminants and co-absorbed product is partially regenerated in a high pressure recycle loop and returned to the absorption stage. The co-absorbed product gas and gas contaminants removed from the solvent in the regeneration stage are released as a discharge gas.
