In existing flue gas treatment projects, as the demand for the coordinated removal of CO, NOx and VOCs continues to grow, conventional layered treatment often requires the addition of multiple catalyst layers, along with corresponding modifications to the reactor, flue ducts and supporting facilities. The more catalyst beds involved, the broader the scope of the retrofit, resulting in higher equipment, installation and construction coordination costs.
Multiple Functions in a Single Bed, Reducing Repetitive Arrangements at the Source
TONEXUS Multi-Functional Catalyst integrates three functions—CO oxidation, SCR denitrification and VOC oxidation—into a single catalyst, enabling the coordinated treatment of CO, NOx and VOCs through multiple functions in one catalyst bed.
Compared with conventional layered arrangements, the Multi-Functional Catalyst reduces the need for separate CO, SCR and VOC catalyst layers, thereby decreasing reactor volume, flue duct modifications and installation work, while making the overall system more compact.
Existing SCR Systems Can Also Be Upgraded Directly
For projects with existing SCR systems, the Multi-Functional Catalyst can be used for replacement upgrades or integrated into the original system. This enhances the coordinated treatment of CO and VOCs while minimizing modifications to the flue ducts.
Retrofit Costs Should Be Reduced Across the Entire System
The value of “multiple functions in a single bed” lies not only in reducing the number of catalyst beds, but also in simplifying the entire treatment system through functional integration:
By moving from layered treatment to multiple functions in a single bed, TONEXUS Multi-Functional Catalyst reduces repetitive arrangements and provides a more compact, cost-effective and practical treatment solution for both new projects and upgrades to existing systems.
