This article provides practical guidance for the use of Henry's law in design calculations, with emphasis on solutes in aqueous systems at conditions characteristic of wastewater cleanup operations. Particular attention is given to the temperature dependence of the Henry's constant, which is often ignored but which can be crucial for accurate process design. Methods are analyzed for estimating reasonable values of Henry's constant at the temperature of interest when data are only available at a different temperature. Other common pitfalls in the practical use of Henry's constants are discussed; these include confusion about units and the complication of solutes that undergo dissociation or other reactions in the liquid phase.
