Cone - Bottom Tanks

The cone-bottom in either the bolted or the welded tank offer a means of draining and removing water or water-cut oil, from only the bottom of the tank, leaving the marketable oil above. The drain line from a sump-equipped cone bottom must be equipped with a vortex breaker to drain off most of the water without coning oil into the drain. With a flat-bottom tank, some of the marketable oil must be removed if all the water is removed from the tank. Corrosion on the tank bottom is kept to a minimum by keeping all water removed. A cone bottom can be kept clean without having to open the tank if 1 or 2 bbl are drained off once or twice weekly and pumped back through the treating system. If this is not done and the bottom solidifies, the tank must be opened. The cone-bottom tank can be cleaned without entering. A water hose, handled just outside the cleanout opening, can be used to flush the solids to the centre of the cone and drain connection.
