How to Effectively Manage and Reduce Emissions in Sulfuric Acid Plants Using State-of-the-art MECS® Catalysts

Major sulfuric acid plant producers worldwide have installed MECS® Catalyst since the 1920s. Over the past 90 years, the dedicated Research and Development team at MECS, Inc. (MECS) has evolved catalyst from pellets to energy-saving rings to low-emission cesium-promoted catalyst. As energy savings and environmental concerns create new operational and design challenges for sulfuric acid plants, innovations in catalyst technology provide the solution. This paper will detail the MECS® Catalyst portfolio of vanadium-based and cesium-promoted catalysts for sulfuric acid, including the latest innovations, GEAR® catalyst and improved formulation cesium catalyst. The benefits of lower SO2 emissions, increased acid production, energy savings, and longer production cycles through utilization of these contemporary catalyst products will be explored. The effective performance of MECS® Catalysts will be highlighted through several case studies that demonstrate low SO2 emissions.
