ABSTRACT:
A method and an apparatus is provided for the separation of liquid-liquid and liquid-solids compositions by flash evaporation in a heated vacuum chamber. The compositions are injected through an atomizing spray nozzle having a spray cone downward of about 30 to 150 degrees. The compositions are preheated and injected under pressure into the preheated vacuum evaporation chamber. The vaporized liquid that is formed is collected in a condenser which draws the vapors by vacuum or pressure differential. Any solids are collected at the bottom of the vacuum chamber as semi-dry or dry solids.
