New Solvent system for Carbon Dioxide Capture

Reducing CO2 emissions from flue gas has become an increasingly important concern as large emissions have resulted in global climate change and a significant increase in global warming commonly known as the greenhouse effect. The state-of-the-art amine absorption process for CO2 removal has several disadvantages such as the high energy requirement for solvent regeneration, mass loss through evaporation, degradation of the solvent and associated plant corrosion. Therefore, in the proposed Phase I effort, Materials Modification, Inc. (MMI) will develop a new efficient and stable solvent(s) system based on functionalized ionic liquids to capture CO2 from coal-fired power plants. Phase II will involve more detailed studies on the efficiency of the solvent system and optimization of the design for industrial scale up operations. Commercial Applications and Other Benefits: Major commercial application of solvents proposed is on capturing CO 2 from flue gas. Other applications are in the field of life support including spacecrafts, submarines, and biogas treatment.
