The use of Eutectic Solvents for the enhanced treatment carbon dioxide gas during the absorption of gases related to the oil industries: a review

Abstract

Global warming is a serious problem caused in part by rising carbon dioxide emissions. Although technologies for capturing carbon dioxide and storing or using it have been developed, they are restricted by the use of hazardous solvents and the formation of dangerous by-products. Research has resulted in the development of non-toxic, efficient, and environmentally friendly solvents. We will look at green solvents used for carbon capture, with a focus on deep eutectic solvents. Temperature, density, and viscosity all influence solvent performance. A few amine solutions in water have been used to absorb GHGs, such as monoethanolamine (MEA). However, they are not environmentally benign. In the wake of research into greener solvents, solvents with high eutectic depth (DESs) have emerged as a unique option. Among the members evaluated hereunder, a DES composed of ChCl/ethylene glycol has an unprecedentedly high gravimetric uptake of 33.7 wt% with good beginning kinetics (25.2 wt% uptakes within 2.5 min) and recyclability. The offered DES also exhibits long-term performance in the presence of water, good resistance to temperature rise, and a relatively low heat of absorption that makes it appealing for regeneration. Even with significant gravimetric uptakes, the DES has considerably less corrosiveness than pure monoethanolamine and ethylenediamine equivalents because of low oxygen/moisture permeability and the hydrogen bonding network that alleviates the corrosion redox cycle. The good qualities found in numerous critical elements of CO2 collection imply that DESs are strong candidates to replace current monoethanolamine-based scrubbing technology and need further investigation. The carbon dioxide absorption in DES has been determined to be adequate for capturing carbon dioxide from flue gases while allowing for quick DES regeneration. It's analogous to ionic liquids at normal temperatures. Nearly 95% of the natural gas generated in Iraq's oil fields remains untapped. To investigate Iraqi Journal of Oil & Gas Research
