Solvent Formulation for CO2 Separation from Flue Gas Streams
نویسندگان
چکیده
CO2 separation using reactive solvents is considered to be a technically viable option for capturing of CO2 from flue gas streams. However, the cost of CO2 capture using conventional solvents such as aqueous solutions of monoethanolamine (MEA) is prohibitively high. Nearly half of the total cost is due to operational costs, of which about 70 to 80% can be contributed to the cost of regeneration of the solvent. In addition, the conventional solvents are rather corrosive and can be degraded by many of the contaminants present in the flue gas streams. Therefore, there is considerable incentive to develop solvents that require lower energy for regeneration and also induce less operational difficulties. This paper will provide a critical review of the chemical solvent based processes for the separation of CO2 from combustion gas streams and describe the main parameters affecting the process performance.

Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...
