Methods Used To Remove Gas From Oil In Separators
Because of higher prices for natural gas, the widespread reliance on metering of liquid hydrocarbons, and other reasons, it is important to remove all non solution gas from crude oil during field processing. Technical Data used in the field explained in oil and gas courses in Islamabad. Methods used to remove gas from crude oil in oil and gas separators are settling, agitation, baffling, heat, chemicals, and centrifugal force.
Gas contained in crude oil that is not in solution in the oil will usually separate from the oil if allowed to settle a sufficient length of time. An increase in retention time for a given liquid throughput requires an increase in the size of the vessel and/or an increase in the liquid depth in the separator. Increasing the depth of oil in the separator may not result in increased emission of non solution gas from the oil because “stacking up” of the oil may prevent the gas from emerging. Optimum removal of gas from the oil is usually obtained when the body of oil in the separator is thin-i.e., when the ratio of surface area to retained oil volume is high. Some more details of oil and gas courses in Islamabad are as under.
Moderate, controlled agitation is helpful in removing non solution as that may be mechanically locked in the oil by surface tension and oil viscosity. Agitation usually will cause the gas bubbles to coalesce and to separate from the oil in less time than would be required if agitation were not used. Agitation can be obtained by properly designed and placed baffling.
An inlet degassing element similar to that can be installed on the inlet of the separator to assist in introducing the well fluid into the separator with minimum turbulence and in removing gas from the oil. This element disperses the oil in such a manner that gas can more readily escape from the oil. The oil is rolled over and over as it cascades down the baffles, and the combination of spreading and rolling is effective in releasing entrained gas bubbles. This type of baffling is effective in handling foaming oil.
