Abstract
A separator for separating a first fluid from a second fluid through rotation about an axis of rotation, the first fluid having a density less than the density of the second fluid. In one embodiment, the separator includes a separation chamber mounted for rotation about the axis of rotation. A first weir is positioned in fluid communication with the separation chamber. A second weir is positioned over which the second fluid may pass to exit the separation chamber through a collection chamber. A fluid pressure chamber is positioned radially outwardly from the crest of the second weir to receive the second fluid as it passes over the second weir. The fluid pressure chamber is partially defined by an exit weir over which the second fluid may pass. A gas chamber is positioned in the passageway between the second weir and the exit weir and includes a gas escape passageway through which excess gas may escape from the gas chamber such that a gas barrier is formed to maintain the fluid level between the gas chamber and the fluid pressure chamber at the radial level of the gas escape passageway. A gas introduction passageway is provided through which gas may be introduced into the gas chamb…
