| Abstract Scope |
The gas cleaning section is essential for preserving catalyst activity in sulfuric acid plants. When gas cleaning is inadequate, contaminants reach the catalyst beds, causing increased emissions, pressure drop buildup, or the need to reduce production rates to comply with regulations or avoid blower limitations.
The impact of these contaminants varies significantly depending on their nature. For example, inert dust tends to cover the catalyst surface mechanically, causing a gradual loss of melt and increased pressure drop. Other chemicals in the gas phase react with the catalyst’s active phase or support, causing loss of activity, altered mechanical strength — or both.
Furthermore, catalyst beds within a sulfuric acid converter experience very different operating condition. The same contaminant can behave differently in the different beds.
In this paper, Topsoe shares empirical evidence gathered over several years regarding how different contaminants affect different catalyst beds and overall plant performance. |
