Air‐Water Phase Equilibria of Volatile Organic Solutes
The equilibrium or Henry's constant, Hc, and the mass transfer rate constant, KLa, are the major factors determining the extent of transfer during bubble aeration and in countercurrent packed columns. This study delineates the limits of validity of Henry's law for nonionizing halogenated solutes and presents data on the effects of temperature and the addition of model cosolvents on the Henry's constant. The experimental results are compared with predictions from a semi‐empirical thermodynamic model and from vapor pressure and solubility data. No effect of solute concentration on the solute's Henry's constant was observed up to solute liquid mole fractions of $$10−3 Very high cosolvent concentrations, in excess of $$10 g/L, are required to reduce the solute's Henry's constant. The Henry's constant of the organic compounds studied increases by a factor of approximately 1.6 with each 10°C rise in temperature, representing a very strong effect. Thus, temperature is likely to be a key parameter affecting the extent of removal of volatile organic compounds in gas‐liquid contacting processes.
