To size horizontal three phase separator, we need the following data: Oil rate, water rate, and gas rate. 7. Vortex breakers are generally required on the liquid outlets. Separator K value 42 . . They are a combination of Liquid - Liquid andVapor Liquid separators. io(A "V _/)"6MaL)`/6 This spreadsheet is an excellent example of why we should not use this approach for any engineeering calculation. There is something in your post that I don't understand, basically the higher the difference in densities, the faster the separation of two liquids but what you say is that when the difference is higher we need longer retention time even though the separation is going to be faster. Typical retention (or residence) time used in the Hydrocarbon Industry applications - where the greatest majority of 3-phase separators are applied - is 15 to 30 minutes. Which gives me retention time calculation. Settling theory results in the following relationship. The curves for different droplet sizes shown in Figure 2 are fitted to a 3rd order polynomial (for droplet sizes of 100, 150, and 300 microns). AL)0_BBBR The retention time usually varies between 30 seconds and 3 minutes. Although a separator is highly instrumented, controlling flow, pressure, and temperature to achieve maximum production of water-free, pipeline quality natural gas is a difficult task. aH) _R Untitled8.jpg 20.62KB Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations. 4-Calculation based on input data as following: a- Separator dimension as per manufacturer documents, diameter in inch, length in ft. b- Liquid production as per SWT operator in bb/d. Mesh pads KS and performance parameters [3, 5, 8], Table 5. In this TOTM, we will focus on the application of Souders-Brown approach in gas-liquid separators and present diagram, simple correlations and tables to estimate the Souders-Brown equation constant, KS (the so called sizing parameter). aL)0_(,R I don't have any artical or book where i can refer you to.

In this post I want to share how to size horizontal three phase separator. The occurrences of the various flow patterns are shown in associated three-phase flow pattern maps. ! 12.5-ft separator would also be satisfactory. For scrubber applications with low liquid loadings, the KS values will be primarily dependent on the mist extractor type, and the gas gravity separation section becomes less important. Calculate Leff and Lss = Leff + d/12 for different values of d. Step 3. Sizing of three-phase gas-liquid hydrocarbon-liquid water separators are more complicated and will be discussed in another TOTM. , Shell & Tube Heat Exchanger Safety Design, This is not recommended for shared computers. Fluid properties (note temperature has a large impact on fluid properties), Vessel length and the liquid level (for horizontal separators), Most importantly mist extractor type and design (e.g. Regressed coefficients for Equation 7 (P in kPa and KS in m/s in SI). The steps used in this post were from Surface Production Operations by Ken Arnold & Maurice Steward. Thank you very much Mr Art Montemayor. Development of a User Friendly Computer Program for Designing Conventional Oilfield Separators. Retention times for water phase is commonly 3 minutes to 30 minutes, depends on laboratory and field data. S;/SH|ZwaK Sizing of the horizontal separators are more complicated. DR.

In a future TOTM we will discuss the droplet settling theory methods which can be used to more accurately quantify separator performance. aH) _R Help with editing, Content of PetroWiki is intended for personal use only and to supplement, not replace, engineering judgment. After 53 years in the business I dont trust ANY engineer regardless of who she/he is to dictate the size and dimension of any process equipment without backing it up with detailed accurate and acceptable calculations. These values are presented in Table 1. Fine-tune your recovery operation to maximize retrieval of hydrocarbons. 12.5-ft separator would also be satisfactory. Dr. Moshfeghian joined JMC Length must be allotted for inlet devices, gas demisters, and coalescers. The recommended retention time will be approximately 2 times the API 12J values for 2 reasons: . The SBA 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 and mist extractor section. Learn methods and guidelines for using stereolithography (SLA) 3D printed molds in the injection molding process to lower costs and lead time. Determination of gas cross-sectional area based on settling theory or empirical correlations, and the other factors include. According to the phase separation results for di erent droplet sizes, Values for 12 Lss /d should be in the 1.5 to 3 range. The seam-to-seam length of the vertical vessel should be determined from the geometry, once a diameter and height of liquid volume are known. Calculate the height for liquid retention time with Eq. aH) A R Is there any other reasons? For vertical separators with no mist extractor devices, Chap 11, Vol 2 of the Gas Conditioning and Processing book presents KS as a function of pressure and liquid droplet size [5]. 1) states that most crude oils are treated to a range of 0.2% to 3.0% BS&W. Currently in Canada, crude oil to pipeline . Synonyms: residence time. Step 5. I have done some other calculationaccordingto an AIChE (1) paper. It is difficult to estimate the size of water droplet that must be settled out of the oil phase. As far as i can understand minimum six inch hight is given so that level controller can perform well.

He is a member of the Editorial Board for the International Journal of Oil, Gas, and Coal Technology and a member of the GPSA Technical Committee Group F. I have attached the spreadsheet. The most common retention time ranges from 3 minutes to 30 minutes, depends on laboratory and field data. 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]. 2. 8 ft SS tall (after rounding up the height). Therefore, the maximum gas velocity which prevents entrainment of liquid is obtained. "(($#$% '+++,.3332-3333333333 *:JZjz ? But I cannot see the algorithm you used. Hence, the water-phase volume is typically determined by a retention time, based on experience. 11 is also valid. 4. 9. Two, a cylindrical box with a 15-in.

For horizontal separators, the sizing depends on (in addition to the droplet size, density of gas and liquid phases, and gas velocity) separator effective length, Le, and the depth available for gas flow, hG, (i.e. In gravity settling, the dispersed drops/bubbles will settle at a velocity determined by equating the gravity force on the drop/bubble with the drag force caused by its motion relative to the continuous phase. 28 was chosen to allow for an easy solution of Eq. The relationship of vessel diameter and length is given by Eq. This is really a liquid-liquid separator. The maximum allowable superficial velocity or other design criteria should be considered for other type mist extractor.
