... DESs are relatively cheap to produce because they are made from inexpensive starting materials and are easy to prepare. DESs can be considered as a good low-cost alternative to ionic liquids in many applications, such as in CO 2 capture, pharmaceuticals, nanotechnology, enhancing oil recovery , electrodeposition, purification of biodiesel, drug solubilization and other various chemical and industrial applications (Ghareh Bagh et al., 2015; Morrison et al., 2009; Gu et al., 2015; Abbott et al., 2015; Mohsenzadeh et al., 2015; Abo-Hamad et al., 2015; Wu et al., 2012). In this study, ChCl based DESs were introduced as absorbents for H 2 O from NG. Theoretical systems for the prepared DESs by mixing HBDs (TEG, diethylene glycol (DEG), ethylene glycol (EG) and glycerol (GL)) with ChCl as HBA were performed using COSMO-RS and TURBOMOLE software. ...
—In recent years, green solvents named deep eutectic
solvents (DESs) have been found to possess significant properties
and to be applicable in several technologies. Choline chloride (ChCl)
mixed with urea at a ratio of 1:2 and 80 °C was the first discovered
DES. In this article, chemical structure and combination mechanism
of ChCl: urea based DES were investigated. Moreover, the
implementation of this DES in water removal from natural gas was
reported. Dehydration of natural gas by ChCl:urea shows significant
absorption efficiency compared to triethylene glycol. All above
operations were retrieved from COSMOthermX software. This article
confirms the potential application of DESs in gas industry.
