Title (EN) CARBON DIOXIDE UPGRADE AND ENERGY STORAGE SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE VALORISATION DE DIOXYDE DE CARBONE ET DE STOCKAGE D'ÉNERGIE
Abstract:
(EN) A method for producing work is disclosed. The method includes increasing the pressure of a working fluid including carbon dioxide from a first pressure at least equal to a triple point pressure to a second pressure above the triple point pressure. The method also includes heating the working fluid, extracting mechanical work by expanding a first portion of the heated working fluid to a third pressure, supplying a second portion of the heated working fluid as a motive fluid to an ejector, increasing the pressure of the expanded working fluid by supplying the expanded working fluid to the ejector to combine with the motive fluid and form an output fluid at the fourth pressure, the fourth pressure at least equal to the triple point pressure of the working fluid. The method also includes refrigerating the output fluid to condense a vapor phase into a liquid phase.
(FR) La présente invention concerne un procédé de production de travail. Le procédé comprend l'augmentation de la pression d'un fluide de travail comprenant du dioxyde de carbone d'une première pression au moins égale à une pression de point triple à une seconde pression au-dessus de la pression de point triple. Le procédé consiste également à chauffer le fluide de travail, à extraire un travail mécanique par expansion d'une première partie du fluide de travail chauffé jusqu'à une troisième pression, à fournir une seconde partie du fluide de travail chauffé en tant que fluide moteur à un éjecteur, à augmenter la pression du fluide de travail dilaté en fournissant le fluide de travail dilaté à l'éjecteur pour se combiner avec le fluide moteur et former un fluide de sortie à une quatrième pression, la quatrième pression étant au moins égale à la pression de point triple du fluide de travail. Le procédé comprend également la réfrigération du fluide de sortie pour condenser une phase vapeur en une phase liquide.
