Oil purification device for e.g. vehicle engine oil contaminated with water, contains spot heat source for heating contaminant

摘要

At least one spot heat source (3) is used to heat the contaminant present in the oil (17). An oil purification device (1) for oil containing a liquid contaminant comprises a heat source and a transport device (4) for bringing the oil into contact with this heat source, which comprises at least one spot heat source having a predetermined temperature corresponding to the maximum temperature allowed for the oil at the hot point/oil interface. An independent claim is also included for a method for purifying oil using this device.
