Abstract

PURPOSE: To obtain carbon monoxide at a low cost by cooling converter gas after decarburization with gas separated in a rectifying column and further cooling the converter gas to -175°C with circulating nitrogen gas after which the cooled gas is fractionate into nitrogen and carbon monoxide in the rectifying column and the carbon monoxide is taken out from the bottom of the column.
