The size of oil droplets is very crucial in any oil water separation system. We developed a non plugging dynamic centrifugal coalescer. This system increases the oil droplets from a few micron over hundred micron. This allows ‘traditional’ separation devices to remove the oil from the water at a very high efficiency. The dynamic centrifugal coalescer is an combination of centrifugal forces and coalescing effect. An element (core) consisting of thousands of tubes (pore size 0.4 - 1.4mm) is brought into rotation. The multi-phase liquid with different mass-densities passes through the Core. Because of the centrifugal forces, the droplets of the discontinuous phase coalesce on the walls of the tubes. Oil droplets >5 micron increase up to 200 micron. The DCC is a non-plugging coalescing technology and a proven solution technology for increasing performance of Produced water treatment. Some benefits of the coalescer are:
· Straightforward centrifugal pump technology
· No absorbers, chemicals or consumables needed
· Collects droplets down to 1 micron
· Performs under varying conditions, with respect to volume flow, pressure, temperature, specific gravity and oil concentration
· Applicable for all oil/water separators (hydrocyclones, IGF, DAF, CPI, etc.)
· Compact design
· Allows for steep increase of hydraulic capacity of separators
· 3 models cover capacity range up to 200 m3/hr (30.000 BWPD)
· Ability to perform low cost, non-disruptive testing
· Limited capex and opex requirements
· Tolerant to high motion operation (FPSOs)
· Long operating life
· Minimal maintenance requirement The dynamic centrifugal coalescer can be used in new systems for produced water but you can also upgrade existing systems, other applications are; Well testing, Run-off water / Bilge water, Slopwater treatment, Frac fluids, Waste water clean up |
