MECS® Sulfuric Acid Catalyst: Celebrating 100 Years of Innovation

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. Today, sulfuric acid is one of the most utilized commodity chemicals in the world with widespread applications in the phosphate fertilizer, non-ferrous metals, chemicals, and oil refining industries. In the early 1900s, the contact process for sulfuric acid production was improved greatly with the development of vanadium-based sulfuric acid catalysts. Previous sulfuric acid manufacturing using lead chamber units or contact processes utilizing platinum catalysts was expensive, unreliable, and produced lower strength acids.

Acid Absorption Tower Problems through Process Parameters

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 designed to remove acid droplets from the exiting gas stream and retain the acid inside the tower. It is easy to assume that poor demisting performance means poor mist eliminator design or condition. However, that may or may not follow. It has been said that 99% of “mist eliminator problems” are not due to problems of the mist eliminator itself. Though this percentage may not be accurate, experience suggests its order of magnitude is correct.
