A new catalyst reduces SO2 emissions from H2SO4 plants

摘要

At last month's Sulfur 2010 Conference (November 1-4; Prague, Czech Republic), Haldor Tops0e A/S (Lyngby, Denmark; www.topsoe.com) introduced its latest sulfuric-acid catalyst, VK-701 Leap5, which promises to help operators of sulfuric acid plants meet more-stringent S02-emission limits. When used in the final pass of single absorption H2SO4 plants, VK-701 Leap5 reduces SO2 emissions by up to 40% compared to existing catalysts.
