Abstract: Impurities are separated from a liquid in a non-rotary centrifugal separator the walls of which are heated. In the separation of a catalyst particles from oil the temperatures of the material treated is raised by 2 DEG C. and in the separation of water from an oil and water emulsion the temperature is raised by p 3 DEG C. The Specification gives dimensions of and performance figures for a hydro-cyclone.
