AMINE TREATING PROCESS FOR SELECTIVE ACID GAS SEPARATION |
摘要 |
A process for the selective separation of hydrogen sulfide from gas mixtures containing carbon dioxide as well as other acidic gases uses severely sterically hindered amino alcohol absorbents based on amino alcohols and ethers containing secondary nitrogen atoms hindered by an alpha tertiary carbon atom. Preferred absorbents include 2-(N-methylamino)-2-methylpropan-1-ol, (2-(N-ethylamino))-2-methylpropan-1-ol, (2-(N-isopropylamino)-2-methylpropan-1-ol, SBAE (2-(N-sec-butylamino)-2-methylpropan-1-ol) and (2-(N-t-butylamino)-2-methylpropan-1-ol.
