sCrude oil flows into a crude oil gutter and then into a vibrating screen to separate
dirt and sludge from crude oil. Dirt and sludge flow into conveyor back to digesters for oil recovery, and crude oil flows into crude oil tank then pumped to the oil room. In the crude oil tank, there is a skimmer to skim the pure oil at the upper layer of the crude oil and straight pump to the pure oil tank.
