ABSTRACT:
Liquids which, when dilute, tend to froth during mixing or boiling are evaporated in an evaporator by feeding the entire liquid quantity to be evaporated into the evaporator, bringing only part of it in indirect heat exchange contact with a hot medium to concentrate the liquid, recycling part of the concentrated liquid to the heat exchange to prevent frothing of the liquid to be evaporated, and withdrawing the vaporized portion and the concentrated liquid from the evaporator.
