Removal of Gas From Oil

The physical and chemical characteristics of the oil and its conditions of pressure and temperature determine the amount of gas it will contain in solution. Technical Data used in the field explained in oil and gas courses in Islamabad. The rate at which the gas is liberated from a given oil is a function of change in pressure and temperature. The volume of gas that an oil and gas separator will remove from crude oil is dependent on (1) physical and chemical characteristics of the crude, (2) operating pressure, (3) operating temperature, (4) rate of throughput, (5) size and configuration of the separator, and (6) other factors.

Rate of throughput and liquid depth in the separator determine the “retention” or “settling” time of the oil. Retention time of 1 to 3 minutes is generally adequate to obtain satisfactory separation of crude oil and gas unless foaming oil is being handled. When foaming oil is separated, retention time should be increased to 5 to 20 minutes, dependent on the stability of the foam and on the design of the separator. Advancements in field processing systems and production procedures-such as automatic custody transfer-emphasize the need for complete removal of no solution gas from the oil. Agitation, heat, special baffling, coalescing packs, and filtering materials can assist in the removal of no solution gas that otherwise may be retained in the oil because of the viscosity and surface tension of the oil. Some more details of oil and gas courses in Islamabad are as under.

In some instances it is preferable to separate and to remove water from the well fluid before it flows through pressure reductions, such as those caused by chokes and valves. Such water removal may prevent difficulties that could be caused downstream by the water-such as corrosion, hydrate formation, and the formation of tight emulsion that may be difficult to resolve into oil and water.

The water can be separated from the oil in a three-phase separator by use of chemicals and gravity separation. If the three-phase separator is not large enough to separate the water adequately, it can be separated in a free-water  knockout vessel installed upstream or downstream of the separators. If the water is emulsified, it may be necessary to use an emulsion treated to remove it. through are illustrations of three-phase separators.
