Api oil water separator calculation. Patrick pj dorn last modified by. Oil water separators are typically considered very simple devices. Different design criteria must be used in sizing and selecting a separator for a hydrocarbon stream based on the composition of the fluid mixture. A x r x 0 0104 tfr example.
Specific gravity of the oil in g cm3 0 850. One 2acre 43 560 ft in south central pennsylvania. Jim kornak created date. Cross section velocity is also determined to ensure the maximum velocity of 3 fpm is not exceeded.
43 560 x 2 x 0 0104 906 05 gpm or indoor applications. User input in yellow. Design flow rate in gpm 250. Viscosity in poise 0 01129.
The liquids from the gas phase is accomplished by passing the well stream through an oil gas or oil gas water separator. Calculate treatment flow rate the formula to determine the treatment flow rate tfr in gallons per minute gpm is. Oil droplet size in microns 150. Api separator calculations.
Density of the water in g cm3 0 99890. Api style oil water separator sizing calculation. Specific gravity of the wastewater s oil phase wastewater s absolute dynamic viscosity in poise results 0 9984 density of the water s g g cm3 0 0105 viscosity in poise 0 2711 rise rate of oil droplet gpm ft2 calculated 1475 20 horizontal surface area area ft2 of the separator needed to achieve desired oil removal performance 42 media coalescing area ft2 ft3 35 12 cubic feet ft3 of media volume calculated minimum 2 97 cross sectional velocity ft min. Api calculations viscosity calcs.
To calculate the size of an empty vessel api or api type gravity separator it is first necessary to calculate by the use of stokes law the rise velocity of the oil droplets. In the case of low pressure oil wells the liquid phase will be large in. 10 15 2001 8 55 40 pm company. For water turbulance short circuiting density vs.
33 1 2 types of separator api tanks see figure 33 1 and plate separators are the more efficient oil separators. However several factors that could potentially affect safety efficiency and proper management must be given careful consideration prior to the installation or modification of any oil water separator or separation system. Api oil water separator equipment sizing spreadsheet author. Api tanks were originally designed by the american petroleum institute api for use in refinery applications but modifications of the design can be used for stormwater treatment.
