Analysis of hybrid membrane and chemical absorption systems for CO2 capture

Abstract

Amine-based absorption of CO 2 is currently the industry standard technology for capturing CO 2 emitted from power plants, refineries and other large chemical plants. However, more recently there have been a number of competing technologies under consideration, including the use of membranes for CO 2 separation and purification. We constructed and analyzed two different hybrid configurations combining and connecting chemical absorption with membrane separation. For a particular flue gas which is currently treated with amine-based chemical absorption at a pilot plant we considered and tested how membranes could be integrated to improve the performance of the CO 2 capture. In particular we looked at the CO 2 removal efficiency and the energy requirements. Sensitivity analysis was performed varying the size of the membranes and the solvent flow rate.

Experimental study on hybrid MS‐CA system for post‐combustion CO2 capture

“…It is therefore necessary to establish a hybrid membrane separation‐chemical absorption system to maximize the intensification for post‐combustion CO 2 capture. There is little research on hybrid carbon capture systems for post‐combustion; most of the studies are at the numerical simulation stage . Thus, a specific experimental study should be implemented to improve research content.…”

Metal-Salen Derivatives for Electro-Reduction of Carbon Dioxide

“…Increasing concerns about the rising level of atmospheric carbon dioxide (CO 2 ), the major cause of global warming, and an energy crisis have prompted the development of new technologies for decreasing carbon dioxide. The problem of atmospheric carbon dioxide concentrations can be alleviated by various technologies such as biological [1][2][3], geochemical [4][5][6], and chemical methods [7][8][9]. Although many technologies and processes seem to be perfect solutions of reducing carbon dioxide, their high budgets and complicated procedures are main obstacles.…”
