Liquid liquid extraction ethylbenzene from mixed xylenes
Hi. I'm student, currently doing plant design for production of BTX. I'm facing problem to separate ethylbenzene from xylene by liquid liquid
extraction. As far as know, most common to separate ethylbenzene from xylenes is extractive distillation. But extractive distillation is hard to
design it and my supervisor suggest to use Liquid liquid extraction as it is easier to design from distillation. But, I don't know what type of
solvent need to be used, and feed to solvent ratio. I already search many journal/patents but couldn't find it.

I'm not saying that's impossible- but it's going to be very difficult.
You might conceivably do it at a low enough temperature where the ethylbenzene is the only one still liquid but, even there, it's going to be a pig.
