Abstract

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.
