For this application length is mainly doing 2 things: References [] provide the details on the droplet settling theory methods which can be used to more edotion quantify separator performance. Separators covered by this specification may be vertical, spherical, or single or double barrel horizontal. Figure 4 shows the location and function of a typical mist extractor in a vertical separator.
In the case of demisting cyclones, the vendor should be consulted in regards to performance for the current operations of interest.
This service is not available if you are a URL user where you do not spi in with an email address. Do you have a question? There are several sources that one can look up the K S —values for different applications. Historically the Souders-Brown equation has been employed as it can provide reasonable results and is easy to use, but has shortcomings in terms of quantifying separator performance. 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 the wellhead and pipeline.
Moshfeghian is a senior member of AIChE and has published more than technical papers on thermodynamic properties and Process Engineering. For more information about these services, visit our website at http: PetroSkills offers consulting expertise on this subject and many others. For vertical separators with no mist extractor devices, Chap editoon, Vol 2 of the Gas Conditioning and Processing book presents K S as a function of pressure and liquid droplet size [5].
For detail of calculations procedure refer to chapter 11 of reference [5]. NOK 1 ,00 excl.
Similarly, the terminal velocity for the other flow regimes 8tth Intermediate and Newton can be derived based on their corresponding expressions for the drag coefficients [3]. Did you enjoy this post?
Once the maximum, V Gmaxgas velocity through the vessel is determined by Equation 6, one can calculate the required minimum cross sectional area of vessel for gas flow by the following equation.
December 28, at 4: I think there should not be the square root on the right hand side of equation 5. Leave us a Comment below! Table 4 provides a summary of mesh pad characteristics and performance parameters. Read more about subscriptions. What technique can I use to design a gas liquid separator for coupling analytical instruments e. Your email address will not be published.
Note for each droplet size a range of K S —values are given for a specified pressure. September 3, at 2: If the calculated value of K SH by Equation 4 is greater than the maximum value of 0.
API Spec 12J
The drag force, F Dis exerted by flow of gas and gravity force, F Gis exerted by weight esition droplet. August 25, at 3: Please contact me to discuss a possible consulting project with your company regarding the design of gas-liquid separators.
Possible typo in equation 5. Mesh pad K S deration factors as a function of pressure [5]. Separators outside the scope of this specification include centrifugal separators, filter separators and desanding separators.
Typical mist extractor in a vertical separator [5]. August 23, at 1: In the December tip of the month TOTM [1], we discussed troubleshooting of gas-liquid separators for removal of liquids from the gas stream leaving the separator.
8ty Droplet settling theory method, 2. The software there does what is not available elsewhere. KS as a function of pressure and liquid droplet size for vertical separators with no mist extractor devices [5].
February 11, at 8: We will consider both vertical and horizontal gas-liquid separators.
