Ethanol dehydration (pervaporation)

A hydrophilic pervaporation membrane pulls water out of near-azeotropic ethanol — crossing the 89 mol% ethanol-water azeotrope that ordinary distillation cannot. Permeate is ~95% water; the retentate is dried past the azeotrope.

Sustainable Aviation Fuel via Alcohol-to-Jet

Bio-ethanol is catalytically dehydrated to ethylene, oligomerized toward a decene-range olefin, then hydrogenated to n-decane — a real synthetic paraffin in the SAF/jet-range carbon-number band. Honesty note: all three reaction steps are stoichiometric conversion models (this solver has no ethanol-dehydration, oligomerization, or hydrogenation kinetics specific to these catalysts), and the oligomerization step is lumped to a single representative product (1-decene, 5 C2H4 -> C10H20) rather than the real broad C4-C16+ olefin distribution a real oligomerization catalyst produces. The final flash is a light-ends/product split, not a full multi-cut fractionation into light-ends/SAF/diesel bands (this build only makes one heavy product, so there's nothing yet to fractionate into separate SAF and diesel cuts).
