Abstract

The (T 1−T 2)/T 1 efficiency of a very small temperature differential thermodynamic cycle operating near a solvent’s critical locus, where T 1 is the higher temperature and T 2 the lower, is shown to be a simple tool for determining the maximum difference in the excess heat of solution between the cycle’s low-temperature liquid side and its high-temperature supercritical fluid side.
