Abstract

En fremgangsmåte for fremstilling av særlig renset vann 38, fra Fischer-Tropsch reaksjonsvann 12, inkluderer i det minste de følgende trinnene: et primært behandlingstrinn som omfatter en likevektsfaseseparasjonsprosess 14, med i det minste et trinn for å fjerne i det minste en fraksjon av ikke-syreoksygenerte hydrokarboner fra FischerTropsch reaksjonsvannet 12, for å fremstille en første vannanriket strøm 16, et andre behandlingsstadium som omfatter i det minste en membranseparasjonsprosess 28, for å fjerne i det minste noen suspenderte faste stoffer og sure oksygenerte hydrokarboner fra i det minste en porsjon av den første vannanrikede strømmen 16, for å fremstille en andre vannanriket strøm 34, og et tredje behandlingsstadium som omfatter et oppløst salt, og organisk fjerningstrinn 36, for å fjerne i det minste noen oppløste salter og organiske bestanddeler fra i det minste en porsjon av den andre vannanrikede strømmen 34.
