Batch process.
An oil and water mixture is settled in a settling tank. Oil and water phases are separated in this tank. Tank has only one outlet at the bottom DN 50.
bottom is elliptical type. a sight glass is on the outlet pipe, half meter away from the outlet. Operator looks at the sight glass, when he sees the phase change, he closes the outlet valve.
In order to make separation more accurate, a suggestion is to simply replace the sight glass with conductivity sensor and outlet valve is controlled by the sensor.
In my opinion, the bottom of the tank is also needed to be modified to cone type and conductivity sensor is installed very close to the outlet.
Anyone has some experiences with this kind of operation?
Thanks in advance.
