Growing levels of greenhouse gases in the atmosphere is of great concern. One of the promising solutions is CO2 capture and sequestration. Ionic liquids are considered as promising candidates for this approach. In this area most of the effort has been focused on identifying a suitable ionic liquid as well as the measurement of their physical and chemical properties in order to run a reliable process simulation to have the primary insight about their performance both financially and environmentally. We utilized COSMO-RS method to first screen several ionic liquids and then investigate their properties in terms of carbon capture ability. Then we use this data to run process simulation in ASPEN PLUS to examine the performance. Finally, we performed a life cycle assessment associated with the CO2 capture process with each ionic liquid. Through the use of COSMO-RS, process simulation and LCA our goal was to identify optimal ionic liquid which can efficiently capture co2 with optimal energy profile and environmental impacts at the same time.
