Regenerative Thermal Oxidiser recently installed at a steel mill in Queensland
The steel mill has come under pressure over the past years to reduce their overall VOC emissions from their site in Queensland.
VOCs or Volatile Organic Compounds are the results of the spray coating processes in the mill. As part of the manufacturing line the steel tubes and hollow sections are sprayed with primer or clear protective coating post being rolled. As the paint from these spray booths dries the solvent that keeps the paint in liquid form evaporates and is emitted into the atmosphere.
By capturing this emission in a booth and transporting it via duct under negative pressure to the treatment system, Clean TeQ was able to apply the RTO technology, effectively reducing the sites VOC emissions.
Clean TeQ, under license from Adwest Technologies in the USA, manufactured the RTO in Australia specifically for the treatment of VOC reduction.
Using the Flameless RTO, the solvent laden air passes through a randomly packed ceramic bed where it is heated to its oxidation temperature.
Inside the combustion chamber the heated air thermally oxidises destroying the VOCs.
The treated air then passes through a second random ceramic bed where it discharges 95% of its heat energy before discharge to atmosphere.
A set of valves then switch the flow of solvent laden air to repeat the process in the opposite direction.
This type of system has been successfully installed and operated in the USA on over 800 applications. Clean TeQ have adapted the system to meet Australia’s stringent regulations on gas appliances and can now offer this technology as a cost effective means of controlling VOC emissions.
