Abstract

The drawbacks of aqueous alkanolamines for CO2 capture at large scale fueled the progress towards the development of alternative solvents such as deep eutectic solvents. However, further knowledge is still required to bridge the gap between lab-scale measurements and the performance of these emerging solvents at industrial scale process conditions. Hence, this contribution is devoted to evaluating the techno-economic feasibility of deep eutectic solvents for CO2 capture through integrating process modeling with a molecular-based equation of state, soft-SAFT. The evaluation is done based on key performance indicators for physical absorption process such as CO2 cyclic capacity, energy of regeneration and total annualized cost.

Keywords: CO2 Absorption, Deep Eutectic Solvent, soft-SAFT modeling, Process modeling, Techno-economic assessment
