Patent
·
OSTI ID:5950838
A process is described for the removal of hydrogen sulfide from a gas mixture comprising at least 80% v of carbon dioxide which comprises: contacting the gas mixture with an aliphatic tertiary amine or an aqueous solution thereof as an absorbent for hydrogen sulfide; regenerating the loaded absorbent to remove substantially all of the hydrogen sulfide and most of the carbon dioxide to provide a lean absorbent containing carbon dioxide in an amount of from 0.2% w to 2% w ; and recycling the lean absorbent to the contacting step.
