Abstract

Systèmes et procédés relatifs à des systèmes de dessalement. Selon certains modes de réalisation, les systèmes de dessalement fonctionnent de manière transitoire et/ou sont conçus pour faciliter un fonctionnement transitoire. Selon certains modes de réalisation, un flux liquide comprenant de l'eau et au moins un sel dissous est mis en circulation dans un circuit fluidique comprenant un système de dessalement. Selon certains modes de réalisation, une partie du système de dessalement (par exemple, un humidificateur) est conçu pour éliminer au moins une partie de l'eau à partir du flux de liquide pour produire un flux de saumure concentrée enrichi dans le sel dissous. Dans certains cas, le flux de saumure concentrée est remis en circulation dans le circuit fluidique jusqu'à ce que le flux de saumure concentrée atteigne une densité relativement élevée (par exemple, au moins d'environ 10 livres par gallon) et/ou une salinité relativement élevée (par exemple, une concentration de sel dissous totale d'au moins environ 25 % en poids). Selon certains modes de réalisation, du sel additionnel est ajouté au flux de saumure concentrée pour produire un flux de saumure à densité ultra-élevée (par exemple, un flux de saumure ayant une densité d'au moins environ 11,7 livres par gallon). Certains aspects concernent un système qui est conçu pour favoriser le rendement énergétique par récupération de la chaleur du flux de saumure concentrée remis en circulation lors de la décharge à partir du circuit fluidique.
