Sulfur Dioxide Solubility in Heat Transfer Oil in the Temperature Range of (293.15 to 313.15) K: Experimental Results and Related Correlations

Abstract

This work evaluates the solubility and average enthalpy of dissolution of sulfur dioxide in heat transfer oil in the temperature range of (293.15 to 313.15) K at 101.3 kPa. The heat transfer oil is a commercial product, consisting primarily of noncyclic and cyclic alkanes. In this study, solubility is expressed in four different units; Henry's constant, Ostwald's coefficient, sulfur dioxide mole fraction, and grams of solute in unit volume of solvent at 101.3 kPa pressure with solubility−temperature relations in the working temperature range.
