We're planning to scale up a process that involves the transfer of an aqueous phase containing a hazardous reagent from a reactor where phase separation takes place to another reactor. As we would like to avoid the use of an additional tank, we were planning to transfer the aqueous solution directly, but we are worried about the possibility that pump functioning would provoke phase separation disturbing. What would be your advice for this type of setup (use of a shock absorber, etc.)?
Have an insight or suggestion?

Re: How can we avoid phase separation during transfer?18 July 2012 at 1:29pmIf the phases are discrete and you can see/measure the interface then you should be able to drain the phases. (I’m assuming it’s a batch system.) If the phases aren’t stable then you need the intermediate tank.
