Three Phase Separation Trainer with DCS Control
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, and air is vented
- Time to reach a 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, water-cut meters plus low/high level and pressure sensors
- Two-level controls – displacer and capacitance sensors
- Pressure control
- Three flow controls with annular, orifice, and turbine meters
- NEW feature water-cut (emulsion) meter in the oil out stream
- Two centrifugal pumps for water and oil
- Oil and water storage tanks
- Complete unit mounted on a steel structure/skid
- Approximate dimensions of process skid – 210 x 400 x 230 cm high (7’ x14’ x 7.5’ high) Dimensions may be adjusted based on room size and layout.
- Variable speed roots type air blower either (New enclosure sizing):
- In a separate enclosure for a remote location in an air-conditioned utility room (approximate dimensions - 838 x 1010 x 886 mm high (33 x 40 x 35 high) or
- option - can be mounted on the main process skid overall skid size is then 2100 x 4600 x 2300 mm high (7 x16 x 7.5 high) Note this will result in the necessity to wear hearing protection due to higher sound levels in the teaching environment (up to 85 dBa @ 1 m)
- Available in all world voltages / frequencies (customer to specify electrical power available on-site)
Controls Options:
- DCS (our standards) Foxboro A2 or Emerson DeltaV. Others can be substituted on request
- 4 - 20 mA (our standard) or Foundation Fieldbus® instruments on request
- Instruments by various manufacturers on request (our standard are Rosemount/Fisher or Foxboro/Samson)
Instrument Air option:
This trainer can be supplied with a dedicated air compressor/receiver/drier to provide the required instrument-quality air on request.
Options:
- Standard 4 - 20 mA or Foundation Fieldbus instruments
