The application of a direct contact heat exchanger to crystallization is examined. Experimentally, the operation takes place in a vertical column where cooling kerosene droplets flow upwards, counter-currently to a saturated, crystallizing magnesium-chloride brine. The crystals deposited upon the brine cooling form a suspension with the brine. The mechanism of heat transfer in the crystallizer is studied by testing the applicability of a model based upon the phenomena of wake formation and shedding behind droplets. Two flow parameters, the wake volume and its rate of shedding are needed for the model to be operable. The wake volume is obtained using dimensions reported in literature.
