摘要

A multiple effect evaporator for use in the distillation of liquids in general and of the kind wherein evaporation takes place on the outside of substantially horizontal heat exchange tubes as a result of the heating of the inside of the tubes. The invention is particularly but not exclusively concerned with the use of such a multiple effect evaporator in the production of water from a solution of non-volatile solutes in water, for example sea water.
