2007). Typical vane-pack characteristics [3, 5, 8]. But I have followed GPSA for my calculation of retention time. It will be a pleasure to enlighten you on precisely why you are dead wrong in not going through all this stuff. The retention time usually varies between 30 seconds and 3 minutes. MrArt Montemayor I think experience is the main thing in designing. This paper provides a simplified approach to sizing 2 and 3 phase separators in low GOR (<2000 scf/STB) applications. The retention time in a separator is determined by dividing the liquid volume inside the vessel by the liquid flow rate. Industry standards for liquid retention time of solution gas break-out are within a range of 1 to 3 minutes in horizontal separators. I wanted to know thecondition'sorcriteriawhich controls selection of L/D ratio. You are basically applying the simple Brown-Souders equation to a 2-phase separator and possibly allowing for surging liquid flows. Untitled8.jpg 20.62KB The first step in oil and gas production is to split the flow up into its individual components with a separator. aH) A R Droplet Size: 500 microns. 13.4-ft separator satisfies the requirements, so you would round up to an 84-in. Can you please tell me the name of the reference? Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. If this data is not available, 10 minutes is recommended for preliminary design. 8 0 obj << /Length 9 0 R /Filter /FlateDecode >> stream And, pay attention to the liquid velocity. 6CINDEXThree Phase (Gas - Oil - Water) Vertical Separator: As per "Petroleum and Gas Field Processing - Hussein K.

I have done some other calculationaccordingto an AIChE (1) paper. If a foaming crude is present, the retention time could be increased by four times its normal values. Already a Member? Holdup, considered for smooth and safe operation of downstream facilities, is defined as . Thanks! When using settling theory or demister sizing in horizontal vessels, one should also consider the gas velocity for re-entrainment. That doesn't make sense. You can learn the details and equations used from the book.

Also if you have access to API 12J. What technique can I use to design a gas liquid separator for coupling analytical instruments like FI and AAS. Thanks chem101 for your comment. As our Forums Director has previously stated, our members should not post their email addresses in our Forums unless they want to initiate a lot of trash, viruses, and other bad things in their email in-box. I have set you my mail id. London, United Kingdom. The given values for Example 3 are listed next: Step 1. 7. 1Approximate shell length for vertical vessels (courtesy of CDS Separation Technologies Inc.). These parameters are approximate only. Assuming a three-phase separator, as shown below, let's explore how you can make the . Untitled6.jpg 9.84KB aH) _R 1. However, I wouldnt put much faith on your comments. These vessels are either vertical or horizontal in shape. 1440 psi NACE 3-Phase Separator was suggested as part of a package. (Macro was used to calculate the different sentimental volume) . ! For illustration purpose, a general procedure based on retention time appraoch is as follows. Yes normalintuitionsays that density differenceis thedrivingforce of liquid liquid separation. See the chapter on Piping and Pipelines in this section of the Handbook. Compute seam-to-seam length with Eq. The working principle for spherical three phase separator is quite similar to horizontal and vertical phase separators. 12.5-ft separator would also be satisfactory.

Gas separation requires minimum space. One, a full-diameter mesh pad can be installed with a blanking annular plate on top. 11 is also valid. 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. "(($#$% '+++,.3332-3333333333 " swiftworks@yahoo.com? A8N0R For three-phase separators, the ratio is in the 1.5 to 3 range. But I cannot see the algorithm you used. Select Accept to consent or Reject to decline non-essential cookies for this use. aL)0_(,R The liquid capacity of most separators is sized to provide enough retention time to allow gas bubbles to form and separate out. This is analogous to a decanting Unit Operation. This is particularly important for separators handling higher liquid loads. Treaters are designed to break the emulsion by applying heat and retention time, causing the water droplets to coalesce and separate from the emulsion to achieve a basic sediment and water (BS&W) specification in oil. AH)%%$8N$/I provides five flow pattern maps for 20%, 40%, 50%, 60%, and 80% liquid phase water cuts (volume basis). 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. 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. 7. The ratio of length to diameter is typically in the 3 to 5 range. In addition, the numbers of parameters that have to be checked to ensure proper separator sizing are relatively high .

So vapor space calculation is not thatimportantor separator design controlling factor. For bubbles or liquid drops in liquid phase, Assuming low Reynolds number flow, Eq. *:JZjz ? The Souders-Brown method 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. I very much appreciate your comment. The vane-pack manufacturer should be contacted for specific information.
