Your email address will not be published. Posted on September 1, at Knowing the actual gas flow rate through the vessel, one can use K S parameter to determine the maximum allowable gas velocity through the vessel and determine the required separator diameter.
It would be more useful if nozzle sizing were also included. Sizing of the horizontal separators are more complicated. March 3, at 2: Read more about subscriptions. The primary separation mechanism is liquid impingement onto the wires, followed by coalescence into droplets large enough to disengage from the mesh pad.
Equation 6 is called Souder-Brown equation and K S is referred to as the design parameter. Leave a Reply Cancel reply Your email address will not be published. September 3, at 2: You might want to look at the applications on my website.
Can you tell me how the length of a Vertical Gravity Apo is sized once the diameter is calculated? Note for each droplet size a range of K S —values are given for a specified pressure.
For detail of calculations procedure refer to chapter 11 of reference . Notify me of follow-up comments by email. The drag force acts to entrain the liquid droplet while the gravity force acts to pull it down. Especially for sizing horizontal separators. Notify me of new posts by email. This is a great discussion. These values are presented in Table 1. The software there does what is not available elsewhere.

There are two methods 8thh sizing sdition separators: February 11, at 8: He is the author of most Tips of the Month and develops technical 8h for PetroSkills. Figure 4 shows the location and function edution a typical mist extractor in a vertical separator. The mist extractor is the final gas cleaning device in a conventional separator.

If the horizontal gas velocity profile is expected to be fairly uniform would need more details to determine this then 2 might not be a concern either. 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 .
If the calculated value of K SH by Equation 4 is greater than the maximum value of 0. For horizontal separators, the sizing depends on in addition to the droplet size, density of gas and liquid phases, and apj velocity separator effective length, L eand the depth available for gas flow, h Gi.
This rate should allow all liquid droplets larger than 10 microns to settle out of the gas.

Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Equation 2 is called Souders-Brown  equation and K S is referred to as the design or sizing parameter. Schematic of a horizontal gas-liquid separator .
This specification covers minimum requirements for the design, fabrication, and plant testing of oil and gas separators and oil-gas-water separators that are used editiob the production of oil and gas, and are located at some point on the producing flow line between editionn wellhead and pipeline. We will consider both vertical and horizontal gas-liquid separators. Start Webshop Product catalog Product presentation. Table 6 provides vane pack performance characteristics [3, 5, 8].
The Souders-Brown method is limited in that it is based on the average droplet size, but cannot quantify the amount of liquid droplets exiting the gas gravity section. For the higher liquid load applications, i.
Vane packs, like mesh pads, capture droplets primarily by inertial impaction.
