Beschreibung
Zusammenfassung:	An emergency distillation column is disclosed, connected to a plant wherein a main distillation column is present. Such connection occurs by means of by-pass of the pipes which supply said main column, which by-pass has stopping means of the liquid which allow the supply of said emergency column when the pressure drops downstream of the main column exceed a preset threshold value. Preferably, said stopping means are shut-off valves. A process of using the emergency is involves continuously measuring a pressure different between inflow and outflow of liquid being distilled and comparing the measured pressure against a dedicated threshold. A plant for the regeneration of waste oils is disclosed, comprising a distillation column, which furthermore comprises the emergency distillation column as disclosed herein.
