Abstract
Selected chemical species in fluid media such as solutions, mixtures of liquids, and suspensions are crystallized by indirect cooling of the fluid media. Crystals are prevented from sticking to the heat exchange surface by pulsating the fluid with a component of pulsation parallel to the heat exchange surface. The crystals can then be separated from the residual fluid.
