ABSTRACT:
A method of evaporating a pure liquid (4) by indirect heat exchange between it and a hotter fluid, said liquid flowing under the effect of gravity along a heat exchange surface (1). The vapor formed flows in the same direction (6) as the liquid (4) and the liquid flow speed is adjusted as a function of the heat exchanged via the heat exchange surface so that at least half of the liquid has evaporated by the time the remaining liquid reaches the bottom of the heat exchange surface.
Application to heat exchanges using a liquid of which only a small volume is available.
