ABSTRACT:
The method is carried out with a self-emptying separator. Used mineral oil is supplied to its centrifuge drum through a central intake. Purified oil is extracted through a run-off. The separator also has another run-off for liquid extracted from the periphery of the drum. The second run-off is supplied from a sampler. A sensor is positioned in the second run-off. The sensor determines the consistency of the liquid. Downstream of the sensor is a water run-off valve. A line branches off between the sensor and the water run-off valve. The line is provided with a circulation-system valve and empties into the intake. When the circulation-system valve is open and the sensor determines from the consistency of the liquid flowing through the second run-off that the liquid is an emulsion of oil and water, it supplies the result to controls. The controls then close the circulation-system valve for a prescribed amount of time. Determination of the consistency of the liquid in the second run-off is continued at prescribed intervals of time by briefly opening the circulation-system valve until the liquid is determined to consist strictly of water. The circulation-system valve is then closed and the water run-off valve opened and kept open until the sensor determines a change in the consistency of the liquid.
