Secondary desalter

Interface measurement in the secondary desalter

Process data

Measuring task:
Interface measurement
Measuring point:
Measuring range up to:
5 m
Crude oil/H20
Process temperature:
+40 … +60 °C
Process pressure:
0 … 0 bar
Special challenges:
Oil/water interface, changing density


To maximize efficiency of the electrostatic grid as it removes contaminants within second and third stage desalters, a crucial point of control is to maintain the oil and water interface just below this grid. Reliable measurement of this level protects the grid from shorting out on the water as well as increasing efficiency of the unit, which ensures the quality of the feed moving into the next process unit.
