EMERGENCY DISTILLATION COLUMN AND USE THEREFOF

An emergency distillation column (2) is disclosed, connected to a plant wherein a main distillation column (1) 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 co...

description An emergency distillation column (2) is disclosed, connected to a plant wherein a main distillation column (1) 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 (28; 33; 35). A process of use of a column (2) is furthermore described as in any one of the preceding claims wherein the pressure difference between inflow and outflow of the liquid being distilled is measured continuously and compared against a dedicated threshold. Finally, a plant for the regeneration of waste oils is disclosed, comprising a distillation column, which furthermore comprises an emergency distillation column (2), as previously defined.
