Sulfuric acid plants using mesh pads in absorbing tower or drying tower service have long been plagued by the relatively short life of stainless steel, alloy 20 or even Teflon® mesh pads. Many plants replace such pads every two or three years and in some cases every year. The best corrosion-resistant alloy ever produced for protection against sulfuric acid is ZeCor®-Z. Only MECS can incorporate this material into TowerGARD® mesh pads.
