Potential Application of Ionic Liquids
and Deep Eutectic Solvents in Reduction
of Industrial CO 2 Emissions
Mohd Belal Haider, Mata Mani Tripathi, Zakir Hussain, and Rakesh Kumar
Abstract Global warming is attributed to CO 2 emissions which are responsible for
climate change. Various industries such as cement manufacturing plants, power plants,
petrochemical industries, iron, and steel are the major contributors of CO 2 emissions.
Carbon capture and storage has been considered as an essential technology to reduce
CO 2 emissions into the atmosphere. Conventionally, amine-based solvents are used
for the CO 2 capture in the industry. These conventional processes suffer from numerous problems such as high vapor pressure, corrosion, degradation of the solvents, and
requirement of high regeneration energy. Ionic liquids (ILs) are widely accepted as the
solvents of next generation having capability to replace the amine solvents for the CO 2
absorption. The non-volatility, superior thermal stability, non-corrosiveness, and low
regeneration energy make them ideal for future perspective. However, ionic liquids
have significantly lower CO 2 solubility as compared to conventional solvents and
requires complex purification step which adds to its cost. Deep eutectic solvents
(DESs) are believed to be IL-analogues having similar property and have shown ability for CO 2 absorption. The potential application of ionic liquids and deep eutectic
solvents as alternatives to amine solvents has been discussed in this chapter.
