Abstract: A tank recirculation assembly comprising a recirculation line that draws fluid from the lower portion of a tank; and a pump that directs the recirculated fluid vertically toward and into the upper portion of the tank. The assembly comprises piping, pumping process and/or nozzles that spray the recirculated fluid across the surface oil inside of the tank. Recirculation is incorporated to enhance the recovery of more and cleaner oil by spraying as much of the surface area of the oil recovery zone to keep it clean. The then dispersed fluid travels down through the pad and reacts to help disperse and remove the interface that conglomerates in between the oil and water interface.
