Title (EN) CARBON DIOXIDE EMISSION REDUCTION METHOD
(FR) PROCÉDÉ DE RÉDUCTION DES ÉMISSIONS DE DIOXYDE DE CARBONE
Abstract:
(EN) Carbon dioxide emissions within a refinery are reduced by reforming a hydrocarbon containing feed at low pressure to enhance the conversion of methane to hydrogen and carbon monoxide and thereby reduce methane slip. The hydrocarbon containing feed is composed entirely or at least in part of a refinery off gas. The resulting reformed stream is then subjected to water-gas shift conversion to form a shifted stream from which carbon dioxide is separated. As a result of the separation and the low pressure reforming, hydrogen containing fuel gas streams, that are thereby necessary lean in carbon dioxide and methane, are used in firing the steam methane reformer and other fuel uses within the refinery to reduce carbon dioxide emissions. The carbon dioxide that is separated can be sequestered or used in other processes such as enhanced oil recovery.
(FR) L'invention a pour objet de réduire les émissions de dioxyde de carbone dans une raffinerie par reformage à basse pression d'une charge contenant des hydrocarbures afin de renforcer la conversion du méthane en hydrogène et en monoxyde de carbone et de réduire ainsi les rejets involontaires de méthane. La charge contenant des hydrocarbures est composée entièrement ou au moins en partie d'un effluent gazeux de raffinerie. Le flux reformé résultant est ensuite soumis à une conversion par réaction du gaz à l'eau pour former un flux issu de la réaction, duquel le dioxyde de carbone est séparé. Du fait de cette séparation et du reformage à basse pression, des flux de gaz combustible contenant de l'hydrogène, qui sont donc nécessairement pauvres en dioxyde de carbone et en méthane, sont utilisés pour la chauffe du reformeur de méthane à vapeur et pour d'autres usages de combustibles au sein de la raffinerie afin de réduire les émissions de dioxyde de carbone. Le dioxyde de carbone séparé peut être séquestré ou utilisé dans d'autres processus comme la récupération assistée de pétrole.
