Title (EN) NOVEL METHODS AND APPARATUS FOR OSMOTIC DISTILLATION
(FR) PROCEDES ET DISPOSITIFS NOUVEAUX DE DISTILLATION PAR OSMOSE
Abstract:
(EN) Methods and apparatus are provided for osmotic distillation employing dehydrating aqueous solutions of potassium salts of phosphoric acid, pyrophosphoric acid, acetate, and blends thereof. Methods are also provided for the simultaneous osmotic distillation and removal of carbon dioxide from a sample of relatively low osmotic pressure employing alkaline potassium orthophosphate and pyrophosphate dehydrating solutions.
(FR) Procédés et dispositifs destinés à la distillation par osmose et mettant en oeuvre des solutions aqueuses déshydratantes de sels de potassium d'acide phosphorique, d'acide pyrophosphorique, d'acétate et de mélanges de ces substances. L'invention porte également sur des procédés permettant de réaliser simultanément la distillation par osmose et l'extraction du dioxyde de carbone d'un échantillon à pression d'osmose relativement basse en utilisant des solutions déshydratantes d'orthophosphate et de pyrophosphate de potassium alcalin.
