Abstract
Official abstract text for this publication.
A contaminant-tolerant hybrid scrubbing solvent is provided for post-combustion CO 2 capture and removal, the scrubbing solvent including an amine and a low fraction of ammonia. A stripping carrier having a low latent energy is included for solvent regeneration. In one embodiment, the amine is MEA and the stripping chemical having low latent energy is pentane or an isomer thereof. Processes and apparatus for CO2 removal from post-combustion gases and for solvent regeneration are described.
First claim
Opening claim text (preview).
What is claimed: 1. A process for removal of CO 2 from a post-combustion gas, including: a scrubbing step comprising contacting said post-combustion gas with a scrubbing solvent comprising an amine and up to 3 wt % of ammonia to absorb CO 2 and provide a carbon-rich scrubbing solvent; and a stripping step comprising contacting said carbon-rich scrubbing solvent with a stripping carrier having a low latent heat energy to provide a carbon-lean scrubbing solvent; wherein the st…
