Abstract
The invention involves a process for maintaining a low level of carbon monoxide in a carbon dioxide product stream and also for keeping the carbon monoxide out of the fully shifted synthesis gas. The overall process is a process for treating both fully shifted and partially shifted or unshifted synthesis gas. The carbon monoxide is separately removed by a carbon monoxide stripping column and returned to the partially shifted or unshifted synthesis gas which can then undergo a shift reaction to convert the carbon monoxide to carbon dioxide.
