APPARATUS AND METHOD FOR THE REGENERATION OF QUENCHING OILS

摘要

The present invention discloses an apparatus for the regeneration of quenching oil compositions comprising: a device for extracting fraction of said compositions from a treatment tank; an evaporation circuit comprising a return conduct, a heater and a flash reactor; a heat exchanger for condensing the waste vapors; a waste collector which collects the vapors condensed in the heat exchanger. The invention relates also to a method of application of said apparatus characterized by the fact that each used oil fraction undergoes a programmable number of waste separation cycles in said evaporation circuit.
