The processing of lubricating oil from crude oil in refineries of Washington DC, United States. The purification of the lubricating oil by chemically treating it in agitators. Animation shows that the oil is pumped into the treating tank where it is treated with chemicals. By this, the asphaltic or the tarry material having no lubricating value settles down. The oil is then taken and is pumped into the wash tank for further treatment. In the wash tank, it is mixed with hot water and agitated with air which washes out the chemicals. This oil contains paraffin wax which has no lubricating value and has to be removed. The oil is chilled to remove the wax and then pumped under high pressure through large filter presses. Filter press is composed of steel ring. The side plates are made of perforated steel. A blanket cotton duck, cake space and distillate inlet. The oil is forced through press.
