Abstract
Soln. pumped from the base of evaporators, to be vaporised by direct contact, is delivered wholly or partly to the top of the upstream, hotter, evaporator, (the balance being fed to the same evaporator), in a multiple effect countercurrent evaporator. No separate direct or indirect preheating is employed, provision being made for e.g. 10% extra heat exchange area in the evaporators thermselves, thus cost of supplementary equipment is reduced.
