References [2-4] provide the details on the droplet settling theory methods which can be used to more accurately quantify separator performance. 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. 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. You are basically applying the simple Brown-Souders equation to a 2-phase separator and possibly allowing for surging liquid flows. Some folks want its length to be less than 4 feet. Thanks. 35 % to max. Therefore, the maximum gas velocity which prevents entrainment of liquid is obtained. Oil and water separated from natural gas will come to this three phase separator. How is one to identify the responsibility and liability for the correct performance of the equipment? aL) S But I have followed GPSA for my calculation of retention time.
