Treatment of thermal organic compounds, the case of Tempra3000
In this case, we collaborated with an Italian company, Tempra 3000, which specializes in carrying out various heat treatments in a controlled atmosphere: with the installation of the Venturi Scrubber, we solved several problems faced by the customer. The Scrubber is a filtering system that eliminates the concentration of VOCs (volatile organic compounds) and dust present in a gaseous stream. This system is used when substances need to be removed with the chemical reaction of the water. The abatement of VOCs takes place through a process of solubilization of pollutants from the gaseous phase to the liquid one: the contaminated air passes through the lower part of the tower and it is washed in countercurrent at low speed, ensuring the removal of the pollutants.
Problems
- Insufficient suction points for the extraction of quenching fumes.
- Complex piping line with accumulation points:
- Undersized suction hoods.
- Previous system installed was not enough due to its under sizing.
