ABSTRACT:
An improved system for evaporating liquid to obtain solid residue where by small quantities of a solid are recovered from a first liquid medium and dissolved in another liquid medium. The invention comprises a receptacle for holding the liquid to be treated and structure which localizes entry of an evaporating, or carrier, gas along the wall of the receptacle as it moves downwardly and into contact with the material to be treated. Such localization of inlet gas also provides a relatively quiescent central zone in the receptacle through which exiting gas, carrying evaporated liquid, can be removed without disturbing the flow of inlet gas.
