Elessent Clean Technologies announces a significant milestone in its rich history: 2025 marks the 100th anniversary of MECS sulfuric acid catalyst products. Since 1925, sulfur burning, metallurgical, spent acid, and wet gas sulfuric acid plants around the globe have relied on MECS catalysts to reliably convert sulfur dioxide (SO₂) to sulfur trioxide (SO₃) in nearly every type of converter.

"Our 100-year history is a testament to the enduring trust our customers have placed in MECS,” said Eli Ben-Shoshan, CEO, Elessent Clean Technologies. “This legacy of excellence and innovation underscores our commitment to delivering catalyst solutions that enhance plant performance, optimize efficiency, and reduce environmental impact.”

As Elessent Clean Technologies celebrates this remarkable 100-year milestone, the company remains dedicated to advancing catalyst technologies that meet the needs of the sulfuric acid industry while upholding its commitment to creating a cleaner, more sustainable future.

The MECS sulfuric acid technology has been in use for a century in the phosphate fertilizer, non-ferrous metals (leaching & smelting), oil refining and general chemical industries. MECS technologies feature breakthrough solutions, many of which have revolutionized the performance, quality and cost-effectiveness of customer operations.
