With special emphasis on CO2 separation using ionic liquids. The Division of Energy Engineering at Lule University of Technology, Sweden, has a position available for a doctoral student for the development of a new technology based on ionic liquids to separation CO2 from synthesis gas. The position is financed by Interreg Nord.
Ionic liquids (ILs)are organic salts that are liquids at ambient temperature, they have negligible vapor pressure and a stable and wide liquid range of over 300 K, and they are also good solvents for many organic and inorganic compounds. ILs have shown great potential to be used as liquid absorbents for CO2 separation because of high CO2 solubility relative to other common components, such as H2, N2, CO, O2, and CH4, and lower energy requirement for the regeneration of IL.
The goal of this research project is to develop a thermodynamic model to describe the gas solubility in newly designed ionic liquids. The model will be implemented into the commercial software ASPEN to perform process simulations regarding CO2 separation. Meanwhile, the amine technology will also be investigated as a reference.
The cost and energy consumption using the new ionic liquid technology will be estimated and compared with the reference amine technology. The developed CO2 separation model will be implemented into a biomass gasifier model that is currently being developed in ASPEN within the ongoing HighBio project.
