Oily Water Separation

Coalescing and Separation of
Liquids from Liquids

Atmospheric Oily Water Separator

SERIES A-OWS

Oil and Gas waste water includes small amounts of free or dissolved hydrocarbons and solids that must be removed before the water can be re-used, injected or discharged. The level of removal (particularly for hydrocarbons) and disposal options are typically specified by the client. Treatment to remove dispersed hydrocarbons in the form of oil droplets from water relies on gravity separation, with addition of our unique coalescing plate pack internals. Within the KD separator, so called Skimmertank the process of coalescence takes place; that is, small oil droplets collide and form bigger droplets.

Mobile Oily Water Separator

SERIES M-OWS

KD's Oil Water Separator is a gravity separation device designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size. The design of the separator is based on the specific gravity difference between the oil and the wastewater.

Emulsion Destabilization Skid

SERIES SWANOX

The presence of surfactants in oil and gas waters can cause very stable emulsions, treating this water by the use of chemicals like coagulants in combination with flocculants  requires chemicals handling & storage, specialized personnel and extra transports. The traditional management of oil and gas water is costly and wasteful. Series SWANOX, Treatment Skid, utilizes alternative force to drive chemical reactions in a solution, suspension, or emulsion. The treatment process is very similar to normal chemical coagulation, the difference is that it uses an alternative energy force.

Concrete Oily Water Separator

SERIES C-OWS

KD International supplies engineered coalescing oily water separators for installation inside new prefabricated or to retrofit existing concrete tanks. Our technology can be installed inside existing above or below ground round, square or rectangular tanks. KD´s oily water separators separate free non emulsified oil, hydrocarbons, diesel, gasoline, fuels, from water to below 5 parts per million (ppm). The KD´s oily water separator design can be sized for any flow rate desired in single or multi channel designs to accommodate facility shutdown and maintenance activities without stopping the flow. A wide variety of configurations and features can be provided. When compared to traditional API oil water separators, KD´s separators provides higher oil removal performance and greater efficiency.

Steel Oily Water Separator

SERIES S-OWS

KD International supplies a complete line of cylindrical below-ground, steel oily water separators for stormwater and wastewater applications. These high performance units are custom fabricated to meet and exceed the strict construction and performance criteria. KD´s separators are fabricated in carbon steel and available in single-wall and double-wall constructions. KD´s below ground oily water separators can be designed with leak detection systems and passive cathodic protection systems to protect the steel tanks in the ground. Optional our separators can designed with additional corrosion protection package. With our unique design KD´s separators are suitable for large flow rate´s and are available with a variety of influent and effluent product handling options.

Oil in water Analyzers

SERIES EX100-EX1000

The EX-100 is a side stream analyzer using the fluorescence measurement technique. The EX-1000 has additional benefit of spectral analysis. The introduction of this revolutionary oil in water analyzers began with the EX-100. It was the first on-going maintenance free analyzer to provide continuous uninterrupted accurate measurements of oil concentrations. For the first time, reliable real time data enabled operators to take accurate discharge measurements and thus take the next step to improve efficiency of separation processes and saving money.

API/CPI/TPI Separator (Retrofit)

SERIES Retrofit Package

If your existing API/CPI/TPI, oily water separator is not functioning well, wether due to the design, poor effluent performance or fouling problems, we would be able to retrofit your existing API/CPI/TPI separator tank. These could be old large API pits at refineries or petrochemical plants or above the ground large steel tanks. We will add more plate surface per m3 of separator tank volume and per m2 of separator tank area then the execisting design, therefore we are able to increase efficiency. Important factors we take into consideration are; plate surface area, flow rate’s, sizing, efficiency and probably most important understanding the overall process and possible fouling issue’s. We could scheduele a plant visit, speak to the operators, undertand the system and see if it is worthwhile retrofitting. In close cooperation with the client and our engineering team we will create a customized retrofit design. Once the “Advanced” API/CPI/TPI Separator (retrofit) internals are delivered we can support during installation and start-up all around the world.

CPI/TPI Separator (below ground)

SERIES C-OWS

The traditional CPI and TPI separators have a relatively small plate surface per m3 of separator tank volume and per m2 of separator tank area. It was necessary to maximize the plate surface in order to increase efficiency. This was achieved trough unique design of our coalescing plate’s. These below ground separators could be build prefabricated from special concrete and transport all around the world or build by a local civil contractors. For the project execution of an “Advanced” CPI/TPI Separator (below ground) we normally provide a basics separator layout and detailed design engineering for all internals. All internals including pipes and could be fabricated from PE, carbon steel or stainless steel. Normally the design of these type of separators is customized.

CPI/TPI Separator (above ground)

SERIES A-OWS

The last decade oil and gas companies rapidly developed off and on shore activities.  This generated demand for compact oily water separators. Normally space is very limited on rigs and platforms and weight must be saved to the maximum possible extent. At KD’s “Advanced” CPI/TPI Separator (above ground) the water flows in a laminar stream between the plates in a horizontal direction. Oil is separated by floating upwards along the tops of the coalescing plates to the surface of the separator. Heavier particles at the same time settle along the bottom of the coalescing plates and slide down the plates to be collected in a sludge chamber. Our series separators can be fed by gravity or pumped. Each separator can be equipped with skimmers or integrated oil tank. The separator can be customized and prefabrecated in both carbon and stainless steel and be designed for high range of flow rate’s.

Stormwater Treatment Separator

SERIES SW390

Stormwater that does not soak into the ground becomes surface runoff, which either flows directly into surface waterways or is channeled into storm sewers, which eventually discharge to surface waters. Impervious surfaces (airports, industrial area’s, roads, parking lots and sidewalks) are constructed during land development. During rain storms and other precipitation events, these surfaces (built from materials such as asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains. Water running off these impervious surfaces tends to pick up gasoline, motor oil, heavy metals, trash and other pollutants from roadways, parking lots and other surfaces. Effective control of urban runoff involves reducing pollutant discharges. KD International Oily Water Run-off Separators are widely used to reduce the effects of urban runoff. The separator is designed to treat Free non emulsified oil and solids separation by use of our unique Coalescing Plate Technology.
