CO2 Capture Technology by Using Semi-clathrate Hydrates

Experiments and thermodynamic simulations for continuous separation of CO 2 from CH 4 + CO 2 gas mixture utilizing hydrate formation

“…This may be advantageous characteristics of the hydrate-based gas separation in comparison with the chemical absorption and membrane separation, as no chemical absorbent is necessary and the issues of the costs and maintenances of the membranes can be avoid [7,8]. In addition, the potential cost for hydrate-based CO 2 separation is comparable to other methods [9,10]. Hence, hydrate-based gas separation could be an alternative approach for CO 2 capture and further research and developments need to be performed for the industrial implementation.…”
