    Wet Crude Oil Treatment Plant

    what is Wet Crude? in the beginning of the production from any reservoir the crude oil contains no water and salt; with time it begins to produce large amounts of water and salt, although the density difference guarantee that water stays bellow crude oil in the reservoir, but sometimes water content will with time. wet crude facility was founded to reduce the negative effects of water and salt content, especially on the crude oil production and treatment equipment, the crude oil price, and specification. during wet crude treatment, salt and other impurities are removed from oil, these salts are dissolved in the reservoir water. it is either free water, this thing makes…

    Emulsion Treating Part.2

    Emulsion-Treating Methods An emulsion-treating unit or system will use one or more of the methods to aid in destabilizing, coalescence, and/or gravity separation. Each of these treating methods is discussed separately below. Heating. Using heat to treat crude-oil emulsions has four basic benefits: Heat reduces the viscosity of the oil, which allows the water droplets to collide with greater force and to settle more rapidly. Crude-oil viscosities vary widely, and the curves on this chart should be used only in the absence of specific data. If a crude oil’s viscosity is known at two temperatures, it can be approximated at other temperatures by drawing a straight line along those temperature/viscosity points on…

    what are Emulsions

    Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the most desirable methods of treating the crude oil to contract requirements. Some of these factors are: Tightness of the emulsion. Specific gravity of the oil and produced water. Corrosiveness of the crude oil, produced water, and casing head gas. Scaling tendencies of the produced water. Quantity of fluid to be treated and percent water in the fluid. Paraffin-forming tendencies of the crude oil. Desirable operating pressures for equipment. Availability of a sales outlet and value of the casing head gas produced. Why Remove Water? Wet…
