Using equation: 4. API (Ref. In a 3-phase separator, the vessel itself should be designed to separate the gas that flashes from the liquid, as well as separate the oil and water. For separating two liquid phases, one looks for an L/D which provides for longer settling length. aH) _R HVMoFsTPH{H\(zI"_C)5;;K1\h>S7 aL) |-S Mesh pads KS and performance parameters [3, 5, 8], Table 5. So i calculatedtheoreticalretentiontime necessary for the separation ofheavy liquid out of light liquid and light liquid out of heavy liquid. The relationship of vessel diameter and length is given by Eq. Step 2. At this point, we know that the water-drop removal is the dominant sizing parameter in comparison to the gas capacity. These vessels are either vertical or horizontal in shape. (Macro was used to calculate the differentsentimentalvolume). HT;0[Etz[*9*cHc$T$:P=/%K It says that if you have oil and water mixture you could have 3-5 minute retention time. If the calculated value of K SH by Equation 4 . Liquid retention time is combined from holdup and surge time. Step 2. The primary purpose of three-phase separation is to prepare the oil for further treating. Arnold, Ken, and Maurice Stewart, Surface Production Operations Design of Oil Handling and Facilities Vol 1 3rd Edition, Elsevier, 2008. It will be a pleasure to enlighten you on precisely why you are dead wrong in not going through all this stuff. The mesh pad can be installed in two ways, if the 1.15 ft 2 is to be maintained. 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. To ensure that the liquid and gas reach equilibrium at separator pressure, a certain liquid storage is required.This is defined as "retention time" or the average time a molecule of liquid is retained in the vessel, assuming plug flow. governing factor in sizing separator is gas. AH)0@0S MrArt Montemayor I think experience is the main thing in designing. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
