The two curves for 500 micron droplet size in Figure 2 were divided into 4 and 2 segments based on pressure range for the lower and upper curves, respectively. TWO- AND THREE-PHASE SEPARATOR FABRICATION. A quick search from the book :Petroleum and Gas Field Processing By Hussein K. Abdel-Aal, Mohamed Aggour, M. A. Fahim, "retention time usually range from 3 - 30min", " if lab data are not available, use a retention time of 10 min", attached an excerpt. The SBA can provide reasonable results and is easy to use. Retention time in Three Phase separator depends on operating temperature and densities of liquids. continuous liquid-phase space height, in. ,[I&4 Per API 12J, the maximum allowable superficial velocity, calculated form the above factors, is for separators normally having a wire mesh mist extractor. The gas gravity separation section of a separator has two main functions: Most mist extractors have limitations on the amount of entrained liquid droplets that can be efficiently removed from the gas, thus the importance of the gas gravity section to remove the liquids to an acceptable level upstream of the mist extractor. Sizing the water phase by oil-drop removal is usually not effective. Calculate the required mesh-pad area with Eq. This is analogous to a decanting Unit Operation. July 18, 2017.
