How to handle those with circular logistics?

Thread Content

I’m performing extraction distillation simulations, with the extractant being recycled. At the start of the simulation, I didn’t use recycling, and the results were good; but once the extractant was recovered and reused, it stopped working. Experts, can you tell me what’s going on?

It is possible that the extractant returning in circulation has undergone significant changes in its composition and flow rate compared to before; a comparative analysis can be conducted to examine this

It’s possible that you haven’t regenerated your extractant properly; please take some action to regenerate it and see how it works.

I’m facing the same problem now; with extractive distillation, an error occurs as soon as the extractant starts to circulate! Seek help from experts!
