Equation 2 is called Souders-Brown  equation and K S is referred to as the design or sizing parameter.
Its value depends 88th several factors including:. Do you have a response to this question? The K s method, Equation 2, is an empirical approach to estimate the maximum allowable gas velocity to achieve a desired droplet separation.
Sizing of the horizontal separators are more complicated. Posted on September 1, at It would be more useful if nozzle sizing were also included. Mesh pad K S deration factors as a function of pressure .
Mr Shital Gandhi says: The last row of Table 2 provides the average absolute percent deviation 8tg of the predicted K S by the proposed correlation from the corresponding values of Figure 2 values.
Gas-Liquid Separators Sizing Parameter | Campbell Tip of the Month
Gas-Liquid Separators Sizing Parameter. Pressure vessels covered by this specification are normally classified as natural resource vessels. Figure 4 shows the location and function of a typical mist extractor in a vertical separator. Table 6 provides vane pack performance characteristics [3, 5, 8].
This ensures that you are always up-to-date and saves you both time and money. September 3, at 2: Want to read more articles like this? February 11, at 8: Schematic of a horizontal gas-liquid separator . This rate should allow all liquid droplets larger than 10 microns to settle out of the gas.
API Spec 12J
Mesh pads are the most common type of mist extractors used in vertical separator applications. If the calculated value of K SH by Equation 4 is greater than the maximum value of 0. In the case of demisting cyclones, the vendor should be consulted in regards to performance for the current operations of interest. Did you enjoy this post? Possible typo in equation 5. NOK 1 ,00 excl. I think there should not be the square root on the right hand side of equation 8tj.
For editioon separators, the sizing depends on in addition to the droplet size, density of gas and liquid phases, and gas velocity separator effective length, L eand the depth available for a;i flow, h Gi.
The curves for different droplet sizes shown in Figure 2 are fitted to a 3 rd order polynomial for droplet sizes of, and microns. We will consider both vertical and horizontal gas-liquid separators. The drag force acts to entrain the liquid droplet while the gravity force acts to pull it down and separating it from the gas phase.
If we consider a spherical liquid droplet with a diameter of, D Pin the gas phase two forces as shown in Figure 1 act on it. In the following sections, we will discuss three ediion.
This is typically characterized by a K S —value, as shown in Equation 2.
For practical applications, the first term on the right hand side is replaced by K S. For this application length is mainly doing 2 things: This is particularly important for separators handling higher liquid loads.
