If you've decided that legal separation is the path forward for you and your partner, you'll want to make sure you're following all the necessary steps to ensure it is, in fact, legal.
Traditional oil-water separation hydrocyclone mainly uses different centrifugal force between oil and water to achieve rapid separation. However, with gradual expansion of oilfield polymer flooding, ASP (alkali-surfactant-polymer) flooding, and other oil displacement technologies, viscosity of produced fluid is increasing, and emulsification is …

The hydrocyclone designed has provided total efficiency of E T = 93% with a small flow ratio of R F = 7% which implied reduced total efficiency being E′ T ≅ E T = 93%. It can be noted that for an inlet stream with 40% oil-in-water concentration, the overflow and underflow oil concentrations are 89% and 4% respectively, which shows the high ...

Answer: Flow rate is the most important factor in determining SandMaster Separator size because all LAKOS Separators operate within a prescribed flow range. Pipe size is not a factor in model selection so do not use your existing pipe size to determine the separator size. Required separator size is often, but not always, smaller than the existing piping, …
Hydrocyclone performance is independent of the underflow pressure, provided there is enough backpressure to force enough oil/water out the overflow. This takes a minimum of 50 psi for 35- mm hydrocyclones, although for field use a set point of 60 to 75 psi is recommended. Hydrocy- clone performance is independent of the inlet oil …
