Help needed: problem with water remaining in the benzene-water separation process

Posting on mobile phones doesn’t allow pasting; the issue is on the second floor
Dear teachers, has anyone studied the separation of benzene from water? The separation tank is equipped with a baffle; after the condensate from the tower flows down, it enters the water section, while benzene overflows to the benzene side through the baffle. Currently, there is some benzene at the bottom outlet of the water section – how can this benzene be recovered? Or the separation effect is better
The drainage from the liquid accumulation pack in your reflux tank is connected to a slightly larger storage tank, where sedimentation and separation take place. A glass plate level gauge is installed in this tank; no interface detector is needed. The water at the bottom is then drained away, the oil at the top is recovered, and the mixture in the middle layer is sent back to the tower for further processing. By the way, how much water is involved in this process?
I’m not sure if you’re referring to a decanter; in such a tower, the material to be recovered enters from one side and then separates into layers on the other side – benzene overflows to the oil side at the top, while water is discharged from the bottom. Static separation does not yield good results; this is how we separate styrene from water – the styrene concentration in the water is around 1000 PPm. We then use a backup tower for another stripping process, which reduces the styrene content in the water to several dozen PPm.
In any case, the classification won’t be that precise
