We will consider both vertical and horizontal gas-liquid separators. Some folks want its length to be less than 4 feet.
Gas-Liquid Separators Sizing Parameter | Campbell Tip of the Month
Separators outside the scope of this specification include centrifugal separators, filter separators and desanding separators. The design parameter, K Sin the Souders-Brown equation is an empirical parameter and is a key factor for the sizing the gas-liquid separators vessel diameter as well as for determination of the mist extractor diameter. Aoi values are presented in Table 1. It would be more useful if nozzle sizing were also included. Pressure vessels covered by this specification are normally classified as natural resource vessels.
Table 6 provides vane pack performance characteristics [3, 5, 8]. Thanks for your reply.
For vertical separators with no mist extractor devices, Chap 11, Vol 2 of the Gas Conditioning and Processing book presents K S as a function of pressure and liquid droplet size . The applications optimize the dimensions to achieve the lowest cost vessel. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. Especially for sizing horizontal separators. The drag force, F Dis exerted by flow of gas and gravity force, F Gis exerted by the weight of droplet.
There are several sources that one can look up the K S —values for different applications. Mesh pad K S deration factors as a function of pressure .
This product can only be purchased electronically by customers who have a web subscription agreement. Typical mist extractor in a vertical separator . Mesh pads K S and performance parameters [3, 8rh, 8]. As presented in the Appendix, substitution of expressions for the drag and gravity forces 21j Equation 1, the maximum allowable gas velocity, V Gmaxwhich prevents entrainment of liquid is obtained.

If we consider a spherical liquid droplet with a diameter of D P in the gas phase two appi as shown in Figure 1 act on it. Can you tell me how the length of a Vertical Gravity Separator is sized once the diameter is calculated? PetroSkills offers consulting expertise on this subject and many others.
Along with inlet devices.

Mr Shital Gandhi says: I think there should not be the square root on the right hand side of equation 5. You might want to look at the applications on my website. Notify me of new posts by email.
For horizontal separators, the sizing depends on in addition to the droplet size, edtiion of gas and liquid phases, and gas velocity separator effective length, L eand the depth available for gas flow, h Gi. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
If the horizontal gas velocity profile is expected to be fairly uniform would need apo details to determine this then 2 might not be a concern either.
August 7, at 8: Your email address will not be published. Note for each droplet size a range of K S —values are given for a specified pressure. References  provide 1j2 pad examples. Read more about subscriptions.
What technique can I use to design a gas liquid separator for coupling analytical instruments 8ty. Separators covered by this specification may be vertical, spherical, or single or double barrel horizontal. Each segment was fitted to a linear equation in the form of Equation 7 and its regressed coefficients e and f are presented in Tables 3A and 3B for FPS and SI units, respectively.
