INCREASING OIL/WATER SEPARATOR BY ADDING A COALESCER

Consider contacting either GE Betz or Nalco for their recommendation for a selected oil-in-water demulsifier that may prove more consistently effective at oil-watwer separation.

I would suggest that you contact some of the great many vendors who offer parallel plate separators and ask them if they could install a parallel plate pack in your separator. That would increase your capacity considerably.

roker,
What are you trying to coalesce? The only thing that a coalescing filter can do is disturb the surface tension of a droplet (suspended in a different fluid, normally a gas) to allow collisions between droplets to coalesce into bigger drops that are no longer buoyant in the bulk media. I don't see how that could be applied to an oil/water separator. What am I missing?

Liquid/ Liquid separation such as Oil/ Water is a pretty common duty for a coalescer. Lots of companies supply coalescer packing.

Here are just a few vendors it may be worth contacting or at least reading their information and downloads. You are probably best getting all your operating and fluid property info together and talking to the vendors and see what they suggest.
There quite a few other companies who supply this sort of equipments such as Pall and Knitmesh.

roker,
I believe ( from your post) that the separator you use is operating on a timing basis allowed for the oil to coalesce and then to separate over some weir or other mechanical means (I could be wrong). Obviously, if you manage to coalesce the oil in an early stage and maintan the separation (%) without re-mixing oil in the flow (which I doubt you can manage in an increased flow), you might increase the flow by the percentage of time saved with quicker coalescing process. However, with increased flow (fluid velocity), the entrained oil droplets in the sour water might increase, thus making the upstream coalescer useless.
Also, if some coalescing plate device can be fitted to your horizontal separator, in the receiving chamber, the benefit will be faster coalescing, hence possibility of increasing the flow.
Tell us your configuration, there could be some hope..
cheers,
