Method for separation of carbon dioxide from gaseous mixture and/or flow of gas for use in e.g. oil refinery, involves contacting gaseous mixture and/or gas stream with mixture containing amidine, water and aprotic solvent

摘要

The method involves contacting gaseous mixture and/or gas stream with a mixture containing an amidine, water and aprotic solvent e.g. dialkyl ether, containing an ether and/or ester group such that a partially insoluble amidine-carbon-dioxide adduct or reaction product is provided as outcome. The amidine and the water are provided in a specific ratio before contacting carbon-dioxide, and the reaction product is separated.
