Abstract
An improved heat exchanger in which a liquid is cooled by contacting a surface to crystallize a component therefrom by indirect heat exchange with a fluid on the otherside of the surface, having a layer of a polymeric material, to which the crystallized component does not significantly adhere, on the surface which contacts the liquid, and with said layer being sufficiently thin for efficient heat transfer through the surface. An improved method of crystallizing a component from a liquid by indirect heat exchange by passing the liquid into contact with a surface covered with a thin layer of a polymeric material to which the crystals do not substantially adhere, and cooled by a cooling fluid which is sufficiently cold to cool the liquid to a temperature low enough to form crystals as the liquid contacts the surface.
