Experiments used synthetic mordenite to separate and concentrate sulfur dioxide from a flue gas stream by water driven desorption, a chromatographic phenomenon known as rollup. Results showed that the rollup effect was influenced by temperature, regeneration conditions, and the feed concentrations of sulfur dioxide and water. Increases in the operating temperature past 50 degrees cenigrade retarded the process, resulting in smaller and broader rollup peaks. Air regeneration at 300 degrees centigrade irreversibly decreased the rollup effect. Optimal regeneration occurred in helium at 200 degrees centigrade or in air at 175 degrees centigrade. Increasing the sulfur dioxide feed concentration did not retard the rollup effect, implying that the rollup phenomenon could be cascaded into a multistage process. The ideal water feed concentration was approximately 7.5 percent. 5 refs.
