Description:
The report gives results of tests of a molecular sieve control system for sulfuric acid plant tail gas. The PuraSiv S uses molecular sieve adsorbent material that releases SO2 when heat is applied. The SO2 is recycled for an additional 2-3% production of acid. The report evaluates the PuraSiv S, using data gathered during a 4-week test period. SO2 concentrations were continuously measured and recorded by a DuPont 460/1 Photometric Gas Analyzer at both the inlet and outlet gas streams. Average removal efficiency was 98.0%. Average SO2 emissions during the tests were below 100 ppm.
