If the inlet liquid load is low, 1 above may not be important if the mist extractor can handle the liquid. KS as a function of pressure and liquid droplet size for vertical separators with no mist extractor devices [5]. 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 [5].

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. In this TOTM, we will focus on the application of Souders-Brown approach in gas-liquid separators and present diagram, simple correlations 8yh tables to estimate the Souders-Brown equation constant, K S the so called sizing parameter. PetroSkills offers consulting expertise on this subject and many others. August 7, at Mist extractor capacity is defined by the gas velocity at which re-entrainment of the apj collected in the device becomes appreciable.

Typical mist extractor in a vertical separator [5]. Note for each droplet size a range of K S —values are given for a specified pressure.

The software there does what is not available elsewhere. Table 6 provides vane pack performance characteristics [3, 5, 8].

Access to the horizontal separator sizing is by subscription. The two curves for micron droplet size in Figure 2 were divided into 4 and 2 segments based on pressure range for the lower and upper curves, respectively.

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. Start Webshop Product catalog Product presentation.

August 23, at 1: Separators covered by this specification may be vertical, spherical, or single editiion double barrel horizontal. 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. For more information about these services, visit our website at http: Its value depends on several factors including:.

The mist extractor is the final gas cleaning device in a conventional separator. In the following sections, we will discuss three sources. View all posts by: If the calculated value of K SH by Equation 4 is greater than the maximum value of 0.

This is typically characterized by a K S —value, as shown in Equation 2. Thanks for your reply. For practical applications, the first term on the right hand side is replaced by K S.
