SEPARATORS

Separators separate well fluids produced from oil and gas wells into gaseous and liquid components. A separator for petroleum production is a large vessel designed to separate production fluids into their constituent components of oil, gas and water.

More about separators:

  • Oil and gas separators can have three general configurations: vertical, horizontal, and spherical. The separators all vary in size and are manufactured from multiple configurations of cylindrical shells. Horizontal separators of both monotube and dual-tube shells can be used for two- or three-phase service. A monotube is generally preferred due to greater area for gas flow and oil/gas interface area per unit price, longer retention time, and is easier to clean. Monotubes are also preferred in cold climes due to the proximity of warm gas for heat exchange to prevent freezing. Furthermore, monotubes have lower silhouettes and are easier to stack for multi-stage separation on offshore platforms where space is limited.
  • 2 phase

    • Gas is separated from the liquid with components discharged separately. Oil and gas separators are mechanically designed so that the liquid and gas components are separated from the hydrocarbon steam at specific temperature and pressure.
  • 3 phase

    • Well fluid is separated into gas, oil, and water with the three components being discharged separately. 
    • More about 3 phase separation
    • The gas-liquid separation section of the separator is determined by the maximum removal droplet size using the Souders–Brown equation with an appropriate K factor. The oil-water separation section is held for a retention time that is provided by laboratory test data, pilot plant operating procedure, or operating experience. In the case where the retention time is not available, the recommended retention time for three phase separator in API 12J is used. The sizing methods by K factor and retention time give proper separator sizes. 

Test Separators

  • A test separator (also, “well tester” or “well checker”) allows the separation and monitoring of well fluids. Test separators may be any usual configuration and may be two- or three-phase, permanently installed or portable, and may be equipped with meters for measuring oil, gas, and/or water for potential tests, periodic production tests, marginal well tests, etc.

Production Units

  • A production separator divides produced well fluid from a single or group of wells, or a lease on a daily or continuous basis. Separators can be vertical, horizontal, or spherical and two or three phase. The sizes are variable between 12”-15’ in diameter and 6-70’ long.
