First Claim
Patent Images
1. A process for the separation and recovery of carbon dioxide from waste gases produced by combustible oxidation comprising the steps of:
- producing a waste gas by combustible oxidation;
feeding a flow of said waste gas to a gas semipermeable material that is a molecular sieve or activated carbon;
separating a gaseous flow comprising high concentrated carbon dioxide from said flow of waste gas through said gas-semipermeable material;
wherein adsorption in and desorption from said gas semipermeable material of said gaseous flow comprising high concentrated carbon dioxide is carried out by means of a temperature swing adsorption (TSA) process; and
at least one of feeding at least a portion of said gaseous flow comprising high concentrated carbon dioxide to an industrial production plant and stockpiling at least a portion of said gaseous flow comprising carbon dioxide.

Abstract
A process for the separation and recovery of carbon dioxide from waste gases produced by combustible oxidation is described comprising the steps of feeding a flow of waste gas to a gas semipermeable material, separating a gaseous flow comprising high concentrated carbon dioxide from said flow of waste gas through the gas semipermeable material, and employing at least a portion of the gaseous flow comprising high concentrated carbon dioxide as feed raw material in an industrial production plant and/or stockpiling at least a portion of the gaseous flow comprising carbon dioxide.
