Treater Separator Retention Time Equations. The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in the laboratory but, in the absence of such data, 20 to 30 minutes is a good starting point.
fluidisation. In ball mills, where the grinding time is longer than in a VRM, excessive powder flowa-bility can lead to insufficient or inefficient grinding because the material flows too fast through the mill. In contrast to ball mills, VRMs have a very high in-ternal circulation, a short mill retention time and a
Jul 06, 2015 Step 5. Select a vessel size that satisfies gas capacity, water-drop removal, and liquid-retention time requirements. An 84-in. 13.4-ft separator satisfies the requirements, so you would round up to an 84-in. 13.5-ft vessel. Similarly, a 90-in. 12.5-ft separator would also be satisfactory.
the case of a vertical or spherical separator. This subjects the fluids to a centrifugal force up to five hundred times the force of gravity. This action stops the horizontal motion of the free liquid entrained in the gas stream and forces the liquid droplets together, where they will fall to the bottom of the separator in the settling section.
