Three Phase Separation Trainer with DCS Control
Function: The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravitational separation of the gas, liquid hydrocarbon and water phases. This process trainer blends air, water and refined oil to emulate a crude oil stream. This fluid mixture then flows into a horizontal separator vessel fabricated of clear PVC. Gas flow passes through a secondary vertical 2-phase separator. The separator is equipped with industry-typical process measurement devices. The entire trainer is controlled from an optional distributed control system or dedicated control panel.
Process Highlights:
- Continuously variable flow of process fluids air, water and oil
- Liquids are recycled, air is vented
- Time to reach steady state after a reasonable step change – less than 20 minutes
Equipment Specification Highlights:
- Clear PVC separator vessels and process piping
- 610 x 1830 mm (24” dia. x 72”) horizontal separator
- Electronic process measurement and control system with 5 control loops plus low/high level and pressure sensors
- Two level controls – displacer and capacitance sensors
- Pressure control
- Three flow controls with annubar, orifice and vortex shedder meters
- Six level switches
