Part three through five is dedicated to topics such as: separator construction, factors affecting separation, vessel operation, and separator operation considerations. Now you only need to apportion the space for normal level and maximum level for oil and water. Too high of a gas velocity will result in liquid re-entrainment from the liquid surface, which may flood the demister and cause carryover. But if we use this minimum hight then vessel diameter becomes too big and retention time becomes very very big.

Improvement / straightening of the gas velocity profile. At least thats what I did Edited by thorium90, 06 February 2013 - 12:07 PM. Determine vessel length to meet the required retention time for all phases. How do you decide the size and dimensions of any separator you prescribe or recommend? This spreadsheet provides an easy and simple approach to (2/3 phase and vertical/horizontal) separator sizing. Do you have any comment about L/D ratio? aH) _R *:JZjz ? For three-phase separators, the ratio is in the 1.5 to 3 range. The relationship of vessel diameter and length is given by Eq. aH) A R (or consistent units for, fractional continuous-phase cross-sectional area, fraction of vessel cross-sectional area filled by liquid. The software at my site is designed to provide dimensions to meet the separation criteria and also provide the lowest weight (cost) vessel. Once the maximum, VGmax, gas velocity through the vessel is determined by Equation 6, one can calculate the required minimum cross sectional area of vessel for gas flow by the following equation. Already a member? io(A "V _/)"6MaL)`/6 As far as i can understand minimum six inch hight is given so that level controller can perform well. RE: Retention time for 3 phase separation in horizontal separators MortenA (Petroleum) 5 Feb 13 06:59 If you already know the size of the separator (and the weir height etc. aL) |-S Oil and Gas Facilities. Per API 12J, the maximum allowable superficial velocity, calculated form the above factors, is for separators normally having a wire mesh mist extractor. Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations. governing factor in sizing separator is gas. 10. Untitled4.jpg 45.78KB And you need to check to see which phase is most likely continuous. Thanks Bobby for your advice. Adobe d C The primary purpose of three-phase separation is to prepare the oil for further treating. Table 6 provides vane pack performance characteristics [3, 5, 8].

I think there should not be the square root on the right hand side of equation 5. In the December 2014 tip of the month (TOTM) [1], we discussed troubleshooting of gas-liquid separators for removal of liquids from the gas stream leaving the separator. As presented in the Appendix, substitution of expressions for the drag and gravity forces in Equation 1, the maximum allowable gas velocity, VGmax, which prevents entrainment of liquid is obtained. Please advise. Substitution of CD from Equation 9 into Equation 4 gives liquid droplet terminal velocity, VT, in the gas phase based on the Stokes law.
