摘要

Process for filtering oils comprises feeding the oil through a filter medium arranged in the oil stream. The oil stream is heated to a higher temperature by a heating element before passage through the filter medium. An independent claim is also included for a device for carrying out the process. Preferred Features: The oil stream is heated to 100-180[deg]C, preferably 130[deg]C. Contaminants in the oil stream are thermally decomposed on heating and the condensation products formed can be removed especially by centrifugation.
