Accurate Level Measurement For The Separation of Oil, Water And Sand

VEGA Level Measurement For The Oil And Gas Industry

In the Oil and Gas Industry the separation of oil from other components such as water and sand is essential for subsequent processing steps and is carried out in separators.

The quality of the oil can be affected if the exact measurement of the filling level and exact determination of the position of the interfaces between oil, water and sand isn’t accounted for correctly. The utilised separators increase profitability of the drilling platform by being extremely efficient.

Level Measurement In The Separator With VEGAFLEX 67

VEGAFLEX 67 functions according to the guided microwave principle and is influenced neither by process pressure nor medium temperature. Its sealing concept with an integrated “second line of defense” increases plant safety and reliability. Its application range of +400 °C and +400 bar and independence from the density of the medium allow universal deployment and guarantee high reproducibility in the oil separator.

With its robust, 16 mm-diameter rod probe, it is easy to mount directly in the container as well as inside bypass pipes. Moreover, it can be shortened, which allows simple, individual adaptation to the respective container dimensions.

Separation According To The Gravity Principle

As a result of their different densities, the various components separate mechanically from each other in the separator. To ensure optimal plant utilization, the position of the individual separation layers must be determined.

Radiation-Based Interface Measurement With SOLITRAC 31

Radiation is attenuated to different degrees by different mediums. This physical principle is used to measure the separated layers of vapour, oil, water and sand. SoliTrac 31 measures right through the metallic container wall and is thus totally independent of the pressure and temperature in the separator.

Due to its high reliability and maintenance free operation, SoliTrac is also often used as a redundant measuring system in separators.

Pressure Monitoring With VEGABAR 53

The pressure transmitter VEGABAR 53 reliably safeguards the entire separator from the danger of excessive process pressure. Its measuring cell is maintenance-free and measures process pressures up to +1000 bar.
