New Trends in the Separation of Significant Greenhouse Gases from Flue Gas Streams

Abstract:

The paper is closely related to the challenge of the most important greenhouse gas - carbon dioxide. Both, the effective capture and secure storage of CO₂, is an urgent environmental problem. Approximately ¾ of all anthropogenic emissions of CO₂ are related to the use of fossil fuels. Great attention is given to the absorption processes for the capture of the gas. Carbon Capture and Storage (CCS) is a promising solution for achieving a significant reduction in CO₂- emissions. Capture of combustion gases using standard volatile organic solvents are the source of numerous problems like environmental pollution, instability and corrosivity of such solvents. An effective solution seems to be the use of ionic liquids. Ionic liquids are a relatively new class of compounds, which are chemically and thermally stable and are able to dissolve a wide range of substances. The negligible volatility of ionic liquids is their most important property. Research and development of the CO₂- capture technology has not yet reached the stage of commercial exploitation under economically acceptable conditions. The aim of this article is to show the possibilities of use of ionic liquids in the absorption separation processes for CO₂ -capture.
