Patent ID: 8377263

Claim:
An oil regeneration device, comprising: at least one point source of heat, a transportation device arranged to bring oil, containing a contamination in the form of a liquid, in contact with the at least one point source of heat, wherein the transportation device comprises a support substrate supporting the at least one point source of heat, where the area of the at least one point source of heat being a part of the area of the support substrate, the oil flowing on at least a surface of said support substrate, the at least one point source of heat having a predetermined temperature that, at an interface between the at least one point source of heat and the oil, corresponds to a predetermined maximum allowed oil temperature which, with respect to the dwell time the oil is exposed to the at least one point source of heat, allows the contamination to be at least partially evaporated, the predetermined maximum allowed oil temperature being substantially higher than a specific temperature at which the oil starts to be damaged irrespective of the dwell time the oil is exposed to the at least one point source of heat.
