A Catalytic Exhaust Air Treatment Plant with recuperative heat recovery was installed downstream a manufacturing facility in Asia. By this means the protection of the environment and the sustainable cleaning of the exhaust air are ensured. High thermic efficiency can be guaranteed as the catalytic exhaust air purification is exothermic and the highly efficient heat exchanger enables auto thermal operation.

The CatOx Exhaust Air Cleaning Plant can be operated in complete automatic modus; remote access to CatOx unit control system is possible via the client’s network and a communication processor, the HMI is accessed directly. Thus, the commissioning was possible in remote modus.

The commissioning was realised by the following steps:
- Installation check
- I/O-check
- Cold check of the system
- First start-up of the burner
- Hot check of the system with fresh air
- System check with waste air
- Client’s Acceptance
Engineers from the JFE Group in Asia supported Standardkessel Baumgarte in the various checks of the system. Via video conference, it was possible to navigate the engineers with the help of the flow diagrams. With a mobile phone camera, the individual valve settings could be gone through. Afterwards, the system could be started up. Error messages were recognised and could be jointly analysed by the leading process specialists in Germany and the engineers on site and immediately rectified. The current status of the plant was always visible and operating logs were saved and could be downloaded for analysis. Optimisations of the plant operation could easily be carried out by the commissioning engineer in Germany by modifying the programming of the control system. The control of the burner is programmed in such a way that it reacts flexibly and without delay to temperature fluctuations in changing load cases. The availability of the system can thus always be guaranteed.
The optimisation of the plant operation was carried out for all different operating conditions, different load cases with different volume flows and VOC concentrations.
