ABSTRACT:
An evaporator comprises a plurality of substantially parallel plates mounted for rotation about a common axis and in which provision is made for a condensible vapor to flow across a first face of each of said plates and for a liquid, at least a portion of which is to be evaporated, to flow across the second face of each of said plate, which plates are arranged to be rotatable at such a mean acceleration, measured in a radial direction with respect to said axis of rotation, greater than the acceleration due to gravity, said first face of each of said plates has a surface designed to discourage formation of a continuous liquid film thereon. The evaporator may be used to concentrate solutions, e.g. of depleted brine or aqueous caustic soda.
