Selecting the appropriate filtration technology is critical to meeting today’s safety, performance, and operational reliability requirements. While traditional pressure leaf filters have supported the sulfur industry for decades, many plants are now reassessing their filtration systems in response to increasing performance
Across sulfur burning, metallurgical, spent-acid, and wet-gas sulfuric acid plants, catalyst performance remains central to achieving low SO2 emissions, regulatory compliance, high production rates, and on-stream time. Plant operators monitor SO2 emissions and, as the catalyst degrades, adjust converter temperatures to
Over the past century, the number of sulfuric acid plants operating globally has expanded exponentially. Throughout the 20th century, rapid industrial growth in combination with increasing demand for superphosphate fertilizers led to high demand for the “king of chemicals,” sulfuric acid.
A poorly performing absorbing tower can manifest in poor stack appearance, bad stick test results, bad acid emission testing results, as well as acid sulfate splotches on nearby structural steel members and grade. Absorbing towers are equipped with mist eliminator elements
