"Follow this link "Oil Water/Separator Design Parameters" for information on the accurate design and sizing of Oil/Water Separators". Oil/water separators are designed to separate free and dispersed oils and greases (as well as gross quantities of suspended solids) from wastewater or process streams, making it possible for sensitive downstream equipment to perform as designed.
The design of the separator shall satisfy the requirements of API PUBLICATION 421, Feb. 1990 on DESIGN & OPERATION OF OIL/WATER SEPARATORS and Stokes' law. Separation Cell: The separation cell is designed using elements of American Petroleum Institute's publication 421, Feb. 1990, "Design of Oil-Water Separators" to ensure the best possible ...
Apr 10, 2012· In response to this, the American Petroleum Institute (API) released a new set of sizing criteria in Feb of 1990 that dealt with the emergence of "plate pack style" or "Coalescing" oil water separators. This document, API Publication 421, went about laying out several calculations that would assist end users in determining how much surface area ...

75 to 300µm. For example, API Publication 421 uses minimum sized droplets of 150µm for oil/water sys-tems in refineries. Note that in Stokes Settling the vessel must be sized to ensure laminar or streamline flow; turbulent flow causes remixing. An example of this sizing method in a decanter is contained in Case Study 2, see page 12.

Even the API publication 421, a manual on Design and operation of Oil/Water Separators introduced in 1990, admits that the old API design standards may need to make way for new designs. The need for an evolution in design emerged due to the advent of "enhanced gravity" plate coalescers that began to be introduced to Oil Refineries in the 1950's.
