The separation at the hydrogenation cold high-pressure interface is not good, and the interface position is inaccurate. Are there any effective solutions?

The cold high-pressure phase separation in the residue hydrogenation unit is not effective, and the phase level indication is inaccurate. Are there any good methods or recommended level gauges? Can an emulsifier be used to prevent poor oil-water separation?
Set the liquid level a bit higher; this will allow more time for oil and water to separate, which should be better.
The inaccurate high-level indication is likely due to an incorrect selection of the oil phase density, which results in inaccurate readings by the instrument; calibrating it using the on-site level gauge will resolve the issue
