Abstract
POSTUPAK ZA IZDVAJANJE VODE IZ RAZBLAŽENOG VODENOG RASTVORA N-METILFORMOLINA-N-OKSIDA, N-METILFORMOLINA, MORFOLINA ILI NJIHOVIH SMEŠA, postupak za izdvajanje vode iz razblaženog vodenog rastvora N-metil-formolina-N-oksida, N-metilformolina, morfolina ili njihovih smeša pomoću sredstva za regeneraciju provodjenjem rastvora kroz uredjaj za reversnu osmozu kroz polupropustljivu membranu. Obogaćenu materiju morfolina i N-metilmorfolina možemo na poznat način da prevedemo u N-metilmorfolin-N-oksid. Pri korišćenju ovog postupka pri preradi celuloze, i to pri NMMO-postupku, dobijene materije možemo da vodimo natrag u postupak za koncentrovanje, čime smanjujemo fizičke i hemijske gubitke, čime se smanjuje opterećenje okoline i povećava ekonomičnost.
