Effect of Viscosity of a Deep Eutectic Solvent on CO₂ Capture Performance in an Energy-Efficient Membrane Contactor-Based Process.

ABSTRACT: Greenhouse gas contributions to climate change have driven intense interest in the separation of CO₂ from wet flue gas streams. Deep eutectic solvents (DESs) are an emerging class of highly selective CO₂ absorbents. A prototypical DES, reline, is a mixture of choline chloride and urea. Reline is a thermally stable, nontoxic, and biodegradable solvent with negligible volatility and is inexpensive. We demonstrate a scalable and energy-efficient hollow fiber membrane contactor (HFMC)-based process using a green solvent for CO₂ capture. This process uses reline in HFMC to provide close interfacial interactions and contact between DES and CO₂. This approach overcomes the disadvantages associated with direct absorption in DES and could potentially be a
