he emission of CO2 due to burning of fossil fuel results in increasing the concentration of CO2 in theatmosphere leading towards global warming. The ionic liquid was impregnated in the lords of membrane and contacted withflue gas containing CO2 in counter flow at different temperature, flowrates and pressure. It has been predicted that by theend of 2030 the emission of CO2 can reached up to 40.2 Gt. Membrane technology is an emerging technology used tocapture CO2 from flue gases. The current work is focused to analyze ionic liquid for capturing for post-combustion CO2through hydrophobic non-selective membrane in membrane contactor under low or atmospheric pressure. Slight pressure isapplied only to maintain the interface stable between feed and ionic liquid phases. The ionic liquid was impregnated in thelords of membrane and contacted with flue gas containing CO2 in counter flow at different temperature, flowrates andpressure. The feed gas in ratio of CO2:N2 was fed on one side of membrane while ionic liquid mixed with water in, was fed onthe other side of the membrane. It has been observed that 1-butyl-3-methyl imidazolium ρ-toluenesulfonate ([BSmim][TOS])shows better selectivity. Moreover, as increase in flowrate and temperature showed the decrease in CO2 capture efficiency.
