Abstract
La présente invention concerne un procédé, une méthode et un système de récupération et de concentration de bicarbonate d'ammonium dissous à partir d'eaux usées contenant de l'ammoniac (NH3) utilisant une séparation de gaz, une condensation, et une cristallisation, chacune à des températures de fonctionnement contrôlées. La présente invention comprend 1) l'élimination de l'ammoniac à partir de déchets (boues, semi-solides, et solides et liquides) sans l'utilisation de produits chimiques à une température d'au moins 80 degrés Celsius, 2) la condensation du gaz contenant de l'ammoniac, du dioxyde de carbone et de la vapeur d'eau pour éliminer la vapeur d'eau concentrant la quantité d'ammoniac et de dioxyde de carbone gazeux, 3) la concentration de l'ammoniac et du dioxyde de carbone dans l'eau par des moyens établis, tels que la concentration du gaz à l'aide d'une condensation partielle suivie par le passage du gaz concentré à travers une colonne d'absorption à une température comprise entre environ 20 et 50 degrés Celsius pour former du carbonate d'ammonium et du bicarbonate d'ammonium dissous, ou la condensation totale suivie d'une déshydratation à l'aide d'une osmose inverse, et 4) la cristallisation du carbonate d'ammonium et du bicarbonate d'ammonium dissous concentrés à une température inférieure à environ 35 degrés Celsius pour former du bicarbonate d'ammonium et du carbonate d'ammonium solides.
