Horizontal & Vertical Separator Demonstrator (Enhanced Version) 

The three-phase horizontal separator demonstration apparatus is a small-scale horizontal vessel that performs continuous separation of a mixture of oil, air, and water. The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravity separation of the gas, liquid hydrocarbon, and water phases. This trainer includes a clear horizontal primary separator vessel. The process has manual control valves with flow meters and is intended to demonstrate oilfield separation principles with basic visual/manual operation.

This process trainer blends air, water, and refined oil to emulate a crude oil stream. This fluid mixture then flows into a separator vessel fabricated of clear materials. The oil and water are recycled; the air is vented to the atmosphere.

This proposed unit will be based on our standard design with enhanced flow metering to enable normal qualitative student exercises plus enhanced exercises including:

  • Oil retention time
  • Water retention time
  • Gas (air) retention time
  • Material balance calculations
  • Pipe flow velocity

Enhanced meters will include one of each of:
  • For inlet air flow - averaging pitot with dP gauge 4 to 45 cfm
  • For inlet oil flow- Gear type with digital display 1 to 30l/min (up to 7.5 gallons/min)
  • For inlet water flow - Turbine type with digital display 2 to 20l/min (up to 5 US gallons/min)
  • Transit-time ultrasonic transit time type for discharge flow velocity with digital display:
    • Outlet oil flow ¡V 6 to 68l/min
    • Outlet water flow ¡V 6 to 68l/min
