SCR Catalyst Layer Management

Cormetech Catalyst Management services effectively determine an optimum catalyst replacement or addition plan through performance audits that analyze the remaining potential of the field catalyst, in conjunction with the operating history and projected use of the SCR, outage schedule and other financial and operational factors. As catalyst layers will deactivate at different rates depending upon the fuel fired, the information dictating which layer should be replaced will be generated from our performance audit. This information may also be potentially applied to other fleet units considered at the time. During this process we also evaluate catalyst advancements available to the customer that may improve the performance of the unit. Taking advantage of such product advancements can, in some cases provide more than a 50% performance enhancement or cost reduction compared to installing a new layer of original catalyst.

The primary key to managing SCR catalysts is to determine an optimum catalyst replacement or addition plan. Catalyst additions are typically the first option prior to replacement or rejuvenation, since in most cases, SCR catalyst systems are built with at least one spare layer. Utilization of this layer is generally the best economic option for customers versus removing and replacing or rejuvenating a layer.
