Nut shell filters were designed to separate crude oil from oilfield produced water in the 1970s. Typically, nut shell filters are used as a polishing step to achieve low oil concentrations (<10 mg/L). Oil is collected in the interstitial spaces between the media and periodically removed during a backwash procedure.
It generally contains a cylindrical container that rotates inside a larger stationary container. The denser liquid, usually water, accumulates at the periphery of the rotating container and is collected from the side of the device, whereas the less dense liquid, usually oil, accumulates at the rotation axis and is collected from the center.

Decanting a liquid from a solid. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.
BRT – below rotary table (used as a datum for depths in a well) BS – bend stiffener; BS – bumper sub; BS – booster station; BSEE – US: Bureau of Safety and Environmental Enforcement [6] (formerly the MMS) BSG – black start generator; BSR – blind shear rams (blowout preventer) BSML – below sea mean level; BS&W – basic sediments ...
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
Corexit [1] (often styled COREXIT) [2] is a product line of oil dispersants used during oil spill response operations. It is produced by Nalco Holding Company, an indirect subsidiary of Ecolab. [3] Corexit was originally developed by the Standard Oil Company of New Jersey. [4]

A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities. [1]
