A steady-state one-dimensional multiphase flow model is developed to describe the characteristics of a spray column type direct-contact liquid–liquid heat exchanger. Several models are assumed to describe the interphase heat exchange between water as the continuous phase and organic liquids as the dispersed phase. For small-diameter droplets, it is shown that existing experimental data are best described by a model that assumes the heat transfer is controlled by conduction within the drops.
