Title (EN) CONTROLLED—GRADIENT, ACCELERATED-VAPOR-RECOMPRESSION APPARATUS AND METHOD
(FR) APPAREIL ET MÉTHODE DE RECOMPRESSION DE VAPEUR ACCÉLÉRÉE À GRADIENT RÉGULÉ
Abstract: front page image
(EN)An accelerated vapor recompression apparatus (10) converts incoming flow (35a) to a concentrate (35c) by developing a concentration profile (146) within a tank (30) holding a liquid (23) containing dissolved solids. The resulting curve (160) of saturation temperature of the stratified liquid (23), such as a brine (23) or other material (23), moves away from the curve (162) corresponding to fully mixed conditions. The shift (174, 180) in saturation temperature results in increased boiling without increased energy from a heater (70) or compressor (50). A method (90, 200) of control of the system provides interventions (203, 204, 205, 206) at different levels (92, 94, 96, 98) of control, ranging from mass flows (35) to work of a compressor (50), heat from a heater (70), and a predictive processing (215) of feedback (217) for controlling commands (216) algorithmically.
(FR)L'invention concerne un appareil de recompression de vapeur accélérée (10) qui convertit le flux entrant (35a) en un concentré (35c) en développant un profil de concentration (146) dans un réservoir (30) contenant un liquide (23) comprenant des solides dissous. La courbe de température de saturation résultante (160) du liquide stratifié (23), tel que de la saumure (23) ou une autre substance (23), se déplace de la courbe (162) correspondant aux conditions de mélange complet. Le décalage (174, 180) de la température de saturation provoque une ébullition supplémentaire sans apport supplémentaire d'énergie par une chaudière (70) ou un compresseur (50). Une méthode (90, 200) de régulation du système permet des interventions (203, 204, 205, 206) à différents niveaux (92, 94, 96, 98) de régulation, tels que les débits massiques (35), le travail d'un compresseur (50) ou la chaleur provenant d'une chaudière (70), et un traitement prédictif (215) de la rétroaction (217) pour la commande de régulation (216) algorithmique.
