After several years of reliable performance using MECS® XLP-110, a field demonstration case was conducted in a large, world-class sulfuric acid plant where MECS® XLP-310 was installed in converter passes 3 and 4 in addition to an XLP mix in pass 2.
MECS® PeGASyS™ showed that overall conversion increased from 99.5% to 99.8%. Due in large part to the MECS® catalyst upgrades, the capacity at the plant increased by 12% while SO2 emissions declined by 60% during this multi-year time period.
