May 26, at 7: December 28, at 4: September 3, at 2: For the 8ht liquid load applications, i. I think there should not be the square root on the right hand side of equation 5. Moshfeghian is a senior member of AIChE and has published more than technical papers on thermodynamic properties and Process Engineering.

The last row of Table 2 provides the average absolute percent deviation AAPD of the predicted K S editiom the proposed correlation from the corresponding values of Figure 2 values.

The applications optimize the dimensions to achieve the lowest cost vessel. April 22, at 9: Along with inlet devices.

You might want to look at the applications on my website. If we consider a spherical liquid droplet with a diameter of D P in the gas phase two forces as shown in Figure 1 act on it.

September 18, at 8: Mesh pad K S deration factors as a function of pressure [5]. Mist extractor capacity is defined by the gas velocity at which re-entrainment of the liquid collected in the device becomes appreciable.

If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password.

Table 6 provides vane pack performance characteristics [3, 5, 8]. This product can only be purchased electronically by customers who have a web subscription agreement. One can also use the appropriate value of K S to size the mist extractor in the vessel. The drag force, F Dis exerted by flow of gas and gravity force, F Gis exerted by weight of droplet. Once the maximum gas velocity, V Gmaxthrough the vessel is determined by Equation 2, one can calculate the minimum vessel diameter, D min by Equation 3.

Gas-Liquid Separators Sizing Parameter | Campbell Tip of the Month

Figure 4 shows the location and function of a typical mist extractor in a vertical separator. If we consider a spherical liquid droplet with a diameter of, D Pin the gas phase two forces as shown in Figure 1 act ai it.

Sizing of the horizontal separators are more complicated. 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. The curves for different droplet sizes shown in Figure 2 are fitted to a 3 rd order polynomial for droplet sizes of, and microns.

Please contact me to discuss a possible consulting project with your company regarding the design of gas-liquid separators. August 23, at 1: Please note that extra delivery cost and delivery time may apply for products ordered as hardcopy, as the products must first be shipped from our suppliers overseas. As presented in the Appendix, substitution of expressions for the drag and gravity forces in Equation 1, the maximum allowable gas velocity, V Gmaxwhich prevents entrainment of liquid is obtained.

Do you have a response to this question? Typical mist extractor in a vertical separator [5]. February 11, at 8: Monitoring Standards monitoring edifion a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. It would be more useful if nozzle sizing were also included. For practical applications, the first term on the right hand side is replaced by K S.

Standards monitoring is a free service designed for you who wish to be alerted of changes to or new 8ty of the standards required in your work. Did you enjoy this post? This is typically characterized by a K S —value, as shown in Equation 2.

The drag force, F Dis exerted by flow of gas and gravity force, F Gis exerted by the weight of droplet. For more information about these services, visit our website at http: 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 in the production of oil and gas, and are located at some point on the producing flow line between edtiion wellhead and pipeline.

Do you have a question? Thanks for your reply. Similarly, the terminal velocity for the other flow regimes like Intermediate and Newton can be derived based on their corresponding expressions for the drag coefficients [3].

This dependency of K S on pressure and droplet size is presented in Figure 2 [5]. Can you tell me how the length of a Vertical Gravity Separator is sized once the diameter is calculated? These values are presented in Table 1.
