Raise the liquid level for oil-water separation and increase the separation time, thereby improving the efficiency of oil-water separation!
It could be due to the neutralizing corrosion inhibitor
1. Increase the residence time of water in the dehydration pack. 2. Use an inverse demulsifier. Measure the pH of the wastewater to see if it is above 9.0; if corrosion inhibitors or ammonia have been used, the dosage can be reduced or discontinued.
It must be oil in the emulsion; using a reverse-phase demulsifier is the most effective solution
Pause the corrosion inhibitor, raise the oil-water interface level, and calibrate the interface level.
