Apparatus and methods for conveying a flow of oil-containing liquid into an oil separation skim tank, and skim tanks including the same

摘要

Apparatus and methods for conveying a flow of oil-containing liquid into an oil separation skim tank, and a skim tank incorporating such apparatus and methods, are disclosed. One such apparatus includes at least one diffuser, the diffuser defining an intake opening configured to receive the flow of oil-containing liquid and an exhaust opening configured to convey the flow of oil-containing liquid into the skim tank. The diffuser is configured to cause the flow of oil-containing liquid to have a greater horizontal width at the exhaust opening than at the intake opening, while minimizing vertical divergence of the flow at the exhaust opening.

1. An apparatus for conveying a flow of oil-containing liquid into an oil separation skim tank, the apparatus comprising:
at least one diffuser, the diffuser defining an intake opening configured to receive the flow of oil-containing liquid and an exhaust opening configured to convey the flow of oil-containing liquid into the skim tank; wherein the diffuser is configured to cause the flow of oil-containing liquid to have a greater horizontal width at the exhaust opening than at the intake opening, while minimizing vertical divergence of the flow at the exhaust opening; and wherein the diffuser comprises a planar diffuser comprising spaced apart opposed top and bottom surfaces substantially parallel to each other, and opposed first and second sides which diverge outwardly from the intake opening to the exhaust opening, such that in an operational orientation, the exhaust opening has a vertical height substantially equal to a vertical height of the intake opening, and the exhaust opening has a horizontal width greater than a horizontal width of the intake opening.
