Abstract

Det beskrives en fremgangsmåte for gjenvinning av svovelsyre fra en blanding omfattende svovelsyre og hydrokarboner, fortrinnsvis karbohydrater. I samsvar med foreliggende oppfinnelse omfatter blandingen svovelsyre og karbohydrater, og settes i forbindelse med en anion-selektiv membran, som således produserer en svovelsyrerik filtratstrøm og en strøm som er uttømt for svovelsyre.
