An oily water separator (OWS) (marine) is a piece of equipment specific to the shipping or marine industry. It is used to separate oil and water mixtures into their separate components. This page refers exclusively to oily water separators aboard marine vessels.
Centrifuge oily water separator. A centrifugal water–oil separator, centrifugal oil–water separator or centrifugal liquid–liquid separator is a device designed to separate oil and water by centrifugation. It generally contains a cylindrical container that rotates inside a larger stationary container.
An API oil–water separator is a device designed to separate gross amounts of oil and suspended solids from industrial wastewater produced at oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial oily water sources.
A white box system is a mechanical system installed in the engine room of a ship for controlling and monitoring the engine room bilge water discharge from the vessel. The system consists of all vital components for monitoring and controlling the discharge from the vessel's oily water separator. The white box includes a stainless steel cage with ...
Oil content meters measure how effective the oily water separators on a ship are functioning. [6] If the OCM computes that the oily discharge is above the 15 ppm standard, the oily water separator needs to be checked by the crew. There are three types of oil that the oil content meter needs to check for and they are fuel oil, diesel, and ...
A heated-water bath is probably the most effective method of removing foam bubbles from foaming crude oil. A heated-water bath is not practical in most oil and gas separators, but heat can be added to the oil by direct or indirect fired heaters and/or heat exchangers, or heated free-water knockouts or emulsion treaters can be used to obtain a ...
[1] The company specializes in developing centrifugal oil-water separators. After the Exxon Valdez oil spill in 1989, Costner wanted to find a new way to separate oil from water, so he acquired the company. He found it difficult to promote its products, until BP placed an order for several of the company's devices in the aftermath of the ...
In a centrifugal oil and water separator, the force of gravity is one-thousand [citation needed] times greater that of the coalescing plate pack separator or the petrol interceptor, so the separation is much greater. Not only is the force of separation greater, but there are fewer working parts so maintenance is much easier and cheaper.
