The industrial liquid-liquid separators generally follows the stock's law.  The sizing equations are well described in many resources e.g. Perry's & GPSA handbooks.  However, I couldn't find a way to quantify the seperation improvement if an inlet device has been in the vessel (e.g. simple perforated pipe, baffle,...etc.


Are there empirical formulas to account for these inlet devices? 


Your feedback is highly appreciated...

You should talk to suppliers of devices for such separators. If you are looking to improve performance or increased rates, coalescers provide lots of performance improvement. Also, use your favorite search engine to explore. If you are in the US, you can find lots of suppliers on my website. And a few in Europe.

At the max you can size the separator based on gravity separation or with inlet device like half open pipe. You have to contact the vendor in case of proprietary inlet device.
