ABSTRACT:
An oil refiner is provided with a fluid containment vessel which is divided into an upper chamber and a lower chamber by a domed plate. The vessel also has a top with a fluid channel therein. The vessel lower chamber contains a filter media preferably enclosed in a cartridge. Oil to be refined is conducted first through the fluid channel in the vessel top, then through the filter media preferably being evenly dispersed into a lower region of the filter media by a radially directing nozzle with a plurality of angularly spaced openings therein. After flowing through the filter media the oil passes through the capillaries in the plate onto a dome shaped evaporation surface thereof. The oil spreads over the evaporation surface in a generally uniform manner even when the vessel is tilted from side to side. A plurality of ribs are positioned on the evaporation surface so as to divide the surface into sections such that oil in adjacent sections is restrained from mixing, thereby also making the refiner less sensitive to tilting of the vessel. Volatile contaminants evaporated from the oil are exhausted through a vent and the contaminant free oil exits, under the force of gravity, from the vessel through a conduit, which conduit returns the oil to a storage container.
