The present invention relates to a plan and a process for regenerating degraded heat transfer oil. The plant includes a distillation column for separating heavy components. The distillation column has an upper part and a lower part, the upper part having: a first inlet for receiving degraded oil, and a head having a first outlet for expelling light component vapor. The plant also includes a rectifier, for receiving the vapor, and having: an upper part having a second outlet for expelling light components; and a lower part having a third outlet for expelling regenerated oil. The distillation column further includes a fourth outlet for letting heavy components out in the lower part of the distillation column, a pressure transmitter at the first inlet, a pressure and temperature transmitter at the first outlet, temperature transmitters inside the distillation column, level switches, an automatic valve at the fourth outlet, and an electric resistance for maintaining the oil in a liquid state. |
