De-oxygenation tower

The oxygen must be detached because it encourages certain bacteria to grow. If bacteria grows in the oil it will chunk the porous rock in the oil reservoir. The filtered water drops into the de-oxygenation tower splashing onto a variety of trays causing gases to be released. The gas is sucked out of the tower with vacuum pumps and the water fills the base of the tower. The de-oxygenated water is taken by boosting pumps to the elevated pressure water injection pumps.
