Recommended K value 41 . 10. The approach uses a retention time method which sizes the liquid section of the separator.

Separators are typically sized by the droplet settling theory or retention time for the liquid phase. The liquid capacity of most separators is sized to provide enough retention time to allow gas bubbles to form and separate out. The drag force, FD, is exerted by flow of gas and gravity force, FG, is exerted by weight of droplet. The balance of drag and buoyancy is given as, The drag coefficient is a function of the Reynolds number, Re, and is given by a curve-fit of data (up to a Reynolds number of 5,000) from Perrys Chemical Engineers Handbook. Click Here to join Eng-Tips and talk with other members! For scrubber applications with low liquid loadings, the KS values will be primarily dependent on the mist extractor type, and the gas gravity separation section becomes less important. AH)0S That would mean that when we have two fluid which has similar densities will take more time to separate. Two-phase separators are used to separate gas from the total liquid stream. Size a horizontal separator to remove 100 m drops in the gas phase. Step 5. In a 3-phase separator, the vessel itself should be designed to separate the gas that flashes from the liquid, as well as separate the oil and water. 3-Calculation based on Lss with a factor (not Leff) and OD (not ID) to adjust / compensatecylindrical volume calculation for different separator designs.

For illustration purpose, a general procedure based on retention time appraoch is as follows. Mesh pad KS deration factors as a function of pressure [5]. Field experience indicates that oil content in the produced water from a three-phase separator, sized for water removal from oil, can be expected to be between a few hundred and 2000 mg/l. Sizing of three-phase gas-liquid hydrocarbon-liquid water separators are more complicated and will be discussed in another TOTM. 3.7.2 Retention Time.
