We have an idea to install a coalescer to purify MIBK in the extraction unit (separate aqueous droplet from MIBK). And we have lots of questions: 1. Is a coalescer suitable to this process or are there other methods more suitable? If coalescer is the most suitable, please recommend a calculation handbook. 2. Why do we install plates into a coalescer? Why don’t we install packing like in distillation column? 3. The product from extraction is sent to stripping column and condensed into liquid. Unfortunately, there is emulsion formed between MIBK and water. How can I remove this emulsion or separate into two phases without adding any reagents due to sensitivity of my process?
Have an insight or suggestion?

Re: Is a coalescer suitable for extraction column?2 October 2012 at 11:22am1: Coalescer may be suitable, although depending on the droplet size and amount coming from your extraction column, a separator less prone to fouling such as a cyclonic or inertial impaction device may be suitable.
2: The comparison is not clear, the internal design of the coalescer is to separate the liquid.
3: Evaluate coalescers for breaking the emulsion.
