Title (EN) A CHEMO-THERMAL PLANT
(FR) CENTRALE CHIMIOTHERMIQUE
Abstract:
(EN) A chemo-thermal plant for converting low-temperature thermal energy to high-temperature thermal energy includes a first heat exchanger for recovering low-temperature thermal energy, a processor for vaporizing a first chemical component, and a second heat exchanger for recovering the energy stepped-up by vaporization. The plant further includes a second processor which is connected to the firstmentioned processor and which is arranged to effect a reaction between the vaporized component and a second chemical component. The first chemical component may comprise ammonia and the second sodium carbonate. The second heat exchanger (12) is then connected to transfer liquid ammonia to the first processor (10) which simultaneously constitutes the first heat exchanger, and is connected for transfer of sodium carbonate solution to the second processor (11).
(FR) Une centrale chimiothermique est destinée à la conversion d'une énergie thermique de faible température en une énergie thermique de haute température. Elle comprend un premier échangeur de chaleur pour récupérer l'énergie thermique de basse température, une unité de traitement pour vaporiser un premier composant chimique, et un second échangeur de chaleur pour récupérer l'énergie élevée par vaporisation. La centrale comprend en outre une seconde unité de traitement qui est connectée à la première unité de traitement et est prévue pour effectuer une réaction entre le composé vaporisé et un second composé chimique. Le premier composé chimique peut comprendre de l'ammoniac et le second du carbonate de sodium. Le second échangeur de chaleur (12) est ensuite connecté pour transférer de l'ammoniaque liquide à la première unité de traitement (10) qui, simultanément, constitue le premier échangeur de chaleur et est connecté pour transférer la solution de carbonate de sodium à la seconde unité de traitement (11).
