Abstract

A method of concentrating by freezing a liquid, which comprises injecting a cooling agent into the liquid to form ice therein, said agent evaporating and withdrawing from the liquid, separating the ice from the liquid and further concentrating the liquid by indirect heat exchange and ice separation.
