Abstract
A feed liquid, which can be aqueous, is frozen in tubes of a freeze exchanger by indirect cooling with a cold liquefied refrigerant to form a solid tubular shaped product. A warm liquefied refrigerant is used to indirectly melt a thin layer of the frozen tubular product to release it from the tubes. The freed tubular product is cut into pieces which can be used for cooling purposes and, in the case of ice, to give potable water.
