Carbon Dioxide Capture with Ionic Liquids

The aim of the project is to design a suitable ionic liquid, which is superior to amines, for Carbon dioxide capture from power plants, natural gas and point sources at refineries. Carbon dioxide capture is not only relevant from environmental perspective, but is of industrial relevance in the natural gas sweetening process, hydrogen purification process and ammonia process. Currently, Carbon dioxide capture is dominated by amine-based technologies, which are very energy intensive and less environmental friendly due to emission of the amine-solvents. Ionic liquids (ILs) are salts, with melting points lower than 100 oC, have been proposed as an alternative to the conventional volatile solvents. Ionic liquids bear some interesting properties, such as: low volatility, relatively high thermal stability, non-flammability and high Carbon dioxide solubility.
