Title
(EN) DISCRETE CONSTANT PRESSURE STAGING OF SOLID-VAPOR COMPOUND REACTORS
(FR) ETAGEMENT NUMERIQUE DE LA PRESSION CONSTANTE DES REACTEURS DE COMPOSE SOLIDE/VAPEUR
Abstract
(EN)
A method of transferring and recovering energy comprises selecting a plurality of two or more different compounds comprising a solid reactant absorbent and a gaseous reactant adsorbed thereon, each of said compounds having a different gaseous reactant vapor pressure, substantially independent of the concentration of the gaseous reactant, locating a different one of the compounds in a different one of a plurality of reactors (12, 14, 16, 18) in a first reaction cycle, pressurizing a first portion of reactors (12, 16) at a first pressure, whereby the compound therein desorbs said gaseous reactant in an endothermic reaction, and pressurizing the second portion of reactors (14, 18) at a second pressure whereby the compound therein adsorbs said gaseous reactant in an exothermic reaction, and in a second reaction cycle, pressurizing the first portion of reactors at the second pressure whereby the compound therein adsorbs the gaseous reactant in an exothermic reaction, and pressurizing the second portion of reactors at the first pressure whereby the compound therein desorbs said gaseous reactant in an endothermic reaction, and directing at least a portion of the heat released during the exothermic reactions or at least a portion of heat absorbed during the endothermic reactions to heat exchange means (22, 24, 26) for energy recovery. The invention includes apparatus for carrying out the method.

Une méthode pour transférer et récupérer l'énergie comprend la sélection d'une pluralité de deux ou de plus de deux composés différents comprenant un réactif absorbeur solide et un réactif gazeux absorbé par celui-ci, chacun de ces composés ayant une pression de vapeur de réactif gazeux différente, sensiblement indépendante de la concentration de réactif gazeux, consistant à placer un composé différent dans un réacteur différent parmi une pluralité de réacteurs (12, 14, 16, 18), dans un premier cycle de réaction (12, 16) en pressurisant une première partie des réacteurs à une première pression, ceci permettant au composé s'y trouvant de désorber ledit réactif gazeux au cours d'une réaction endothermique, et en pressurisant la deuxième partie des réacteurs à une seconde pression ceci permettant au composé s'y trouvant d'adsorber ledit réactif gazeux dans une réaction exothermique, et dans un second cycle de réaction (14, 18), en pressurisant la première partie de réacteurs à la second pression pour que les composés s'y trouvant adsorbant le réactif gazeux dans une réaction exothermique, et en pressurisant la second partie de réacteurs à la première pression afin que le composé s'y trouvant désorbe ledit réactif gazeux dans une réaction endothermique, et en dirigeant au moins une partie de la chaleur libérée au cours des réactions exothermiques ou au moins une partie de la chaleur absorbée au cours des réactions endothermiques vers un dispositif d'échange de la chaleur (22, 24, 26) pour la récupération de la chaleur. L'invention comprend également un appareillage pour appliquer la méthode.
