Sludge management system for crude oil storage tanks

Abstract:

A crude oil storage tank includes a bottom wall, a peripheral wall and a top wall that collectively define a storage volume. A first nozzle is arranged at the peripheral wall. The first nozzle is configured to selectively rotate between a first position and a second position to direct a first stream of fluid into the storage volume. A second nozzle is arranged at the peripheral wall. The second nozzle is configured to selectively rotate between a first position and a second position to direct a second stream of fluid into the storage volume.
