چکیده انگلیسی


• P-T-x of a diverse set of refrigerants in different ionic liquid types are modeled.
• Two equations of state based on lattice fluid theory are employed.
• Use is made of 3086 experimental liquid density and 658 solubility datapoints.
• Modeling of all the 88 isotherms studied are found to be acceptable.
• AARDs of %5.773 and %5.771 for SL and ϵ*-Modified SL EOSs, respectively.

Ionic liquids can dramatically improve the efficiency of absorption refrigeration processes due to their negligibly small vapor pressure; where the IL absorbs the refrigerant gas in one stage and subsequently releases the high-pressure gas upon addition of heat. In the current study, phase equilibrium data (P-T-x) of a diverse set of refrigerants in different types of ionic liquids are modeled with the aid of two equations of state based on lattice fluid theory, i.e. Sanchez–Lacombe and ϵ*-Modified Sanchez–Lacombe EOSs. The characteristic parameters of the pure components were determined from a database of 3086 experimental liquid density datapoints for 11 refrigerants and 12 ILs. According to the results obtained by considering the experimental data of 25 binary IL/refrigerant mixtures comprised of 88 isotherms with a total of 658 datapoints, both EOSs can successfully correlate the solubility data with AARDs of %5.773 and %5.771 for SL and ϵ*-Modified SL EOSs, respectively.
