This report is one of several that present results obtained by an Argonne National Laboratory program, Systems Analysis for Waste Carbon Dioxide Utilization. The program includes engineering research - as well as economic and institutional assessments - dealing with issues related to the supply and use of waste carbon dioxide. Studies of supply options emphasize a new method, being investigated by Argonne, of recovering the carbon dioxide that now escapes from smokestacks; this method would avoid the emission of sulfur oxides and nitrogen oxides believed to be precursors of acid rain. Studies of use options relate primarily to increased exploitation of carbon dioxide for enhanced oil recovery. The new method that Argonne National Laboratory is investigating differs from conventional approaches, which attempt to separate carbon dioxide from flue gas after the fuel has been burned in air. The flue gas produced after such a burn is composed principally of nitrogen and a smaller amount of water vapor, a small amount of (excess) oxygen, and oxides of sulfur and nitrogen depending on the fuel - in addition to the carbon dioxide. The sulfur oxides interfere with the separation of carbon dioxide and thus they (primarily sulfur dioxide) must be removed first. The higher the concentration of sulfur oxides, the more expensive the conventional methods of removing those oxides become.
