CA 2625049

A method and apparatus for removing carbon dioxide from a synthesis gas stream containing hydrogen is disclosed. The method includes absorbing the carbon dioxide using a physical solvent under high pressure and then liberating the carbon dioxide in a series of expansion stages where the pressure on the solvent is reduced. The expansion ratio increases with each expansion stage. The apparatus includes expansion stages having throttling devices and expansion tanks operated at increasing expansion ratios. Carbon dioxide is liberated in this manner so as to minimize the energy required compress for transport via a pipe line for sequestration of the gas. Sequestration of the carbon dioxide is preferred to atmospheric venting to curb the release of greenhouse gases.

On présente un procédé et un appareil permettant d'éliminer le dioxyde de carbone à partir d'un filet de gaz de synthèse contenant de l'hydrogène. Ce procédé consiste en l'absorption du dioxyde de carbone en utilisant un solvant physique sous haute pression, puis en la libération du dioxyde de carbone dans une série de phases d'expansion où la pression sur le solvant est réduite. Le taux d'expansion augmente avec chaque phase d'expansion. L'appareil comprend des niveaux d'expansion comportant des dispositifs d'étranglement et des vases d'expansion opérant à des taux d'expansion croissante. Le dioxyde de carbone est libéré ainsi afin de minimiser l'énergie de compression nécessaire pour la séquestration du gaz destiné à être transporté via un pipe-line. La séquestration du dioxyde de carbone est préférable à la ventilation atmosphérique pour réduire les émissions de gaz à effet de serre.
