Floating Skim Units
CWS offers adjustable skim units that can be used to skim recoverable hydrocarbons from produced water and oil recovery tanks. With hundreds of these units — ranging in size from 3″ to 24″ in diameter — in service throughout Western Canada, CWS is a leading industry provider of floating skim units. Our custom-fabricated hinges allow the skim assembly to move with any fluctuations in the normal operating level of the tank. This allows the oil-skimming process to continue uninterrupted and has an advantage over-fixed skim units, which become stagnant should emulsion levels waver. To create your custom floating skim unit, CWS will supply design drawings — based on tank size and nozzle orientation — for your review.
CWS’s FRP/GRE inlet diffusers and floating skim units are the industry standard for submersed noncorrosive tank systems.
In response to the needs of our clients, CWS is now building our skim units with interchangeable, field-replaceable components. This makes our skim units more customizable and more serviceable than ever before. Ask us about our supportless skim unit options for existing tanks.
Inlet Diffusers
Our custom-fabricated converging/diverging inlet diffusers are complete with flow-straightening assembly. Inlet flow diffusers solve the problem of gravity separation of oil from water by preventing incoming fluids from channeling directly to the tank outlet. Converging/diverging inlet diffusers are available in standard sizes from 2″ to 14″, and custom sizes can be made to order.
The converging throat section of the nozzle minimizes the turbulence and cavitations depending upon fluid velocity.
The velocity reduction capability of the nozzle reduces the kinetic energy of the incoming fluid – reducing the shear forces that are the direct cause of the generation of additional emulsion.
Radial Skim Cones
As an industry leader in innovation, CWS has successfully developed and installed fiberglass panel radial skim cones to deflect sludge and solids away from skim outlet nozzles. This has allowed existing producers to apply this technology through the design of FRP panels. FRP panels can then be installed in existing field tanks by accessing man-ways or cleanouts as an economical alternative to new construction of field tanks. CWS has constructed radial skim cones in diameters ranging from 6′ to 60′.
