Researchers from KU Leuven and the University of Bath developed a layered graphite pervaporation membrane with an internal structure that selectively removes water from isopropyl alcohol (IPA) mixtures. The approach targets lower energy use and cost compared to conventional IPA dehydration methods used across pharmaceuticals, electronics, and fine chemicals.

What industrial settings or operating conditions do you think would benefit most from graphite-based pervaporation for IPA dehydration, and what challenges (scale-up, fouling, durability) might hinder adoption?

Isopropyl alcohol (IPA) is a key industrial solvent for the pharmaceuticals, electronics and fine chemicals sectors, among other uses, but methods for making IPA leave water-alcohol mixtures that need to be separated to achieve the purities required for industrial use. A team of researchers from KU Leuven and the University of Bath was investigating lower-energy, lower-cost methods for effecting the separation of water from IPA and hit upon a graphite-based pervaporation membrane that accomplishes the task.
