MEGTEC Catalytic Oxidizer Treating Metal Decorating Emissions

MEGTEC Catalytic  Oxidizer Treating Metal Decorating Emissions

A 3 piece can maker replaced an aging catalytic oxidizer with a higher capacity catalytic recuperative oxidizer (catox) for their wicket oven. The solution provided had exceptionally low capital cost compared to new equipment, allowed increased process line speed, and now (in 2024) has provided over 20 years of reliable performance.

Established company looking for economical replacement oxidizer with lower maintenance. Can coater was previously treating 6,000 scfm of air from a wicket coating oven. With process upgrades, they were able to significantly increase process line speed, which required additional exhaust from the wicket/curing ovens. In addition to the need for more oxidizer capacity, this can coating operation wanted to reduce the solvent build up in the oxidizer inlet ductwork and fans. The solvents used in this process have high boiling points. Cleaning of the process exhaust ductwork and fans prior to the oxidizer was very labor intensive and costly. Can coater wanted to eliminate the solvent cleanup with the new oxidizer.

Greater than 98.6% VOC destruction achieved


We worked with our client and their consultant to develop a solution that meets their capacity requirement, reduces solvent build-up and provides an economical, long life system for their continued growth.

The oxidizer provided was a well built, late model, catalytic recuperative system that had been idle for 3 years. We assisted the consultant in designing a recirculation loop into our oxidizer to address the solvent build up issue they had with the previous oxidizer. The recirculation loop brings clean, hot air from the catalyst exhaust back into the process ductwork, upstream of the oxidizer inlet. This hot air maintained the duct temperature above the condensing point of the solvents, eliminating solvent build up from the point of recirculation tie-in, through the oxidizer.
