Clean exhaust air through an efficient purification process
May 22, 2023
With Dürr's regenerative thermal oxidation process, the polluted exhaust air can be converted into clean process air.
The production of polluted exhaust gases and vapors occurs at various stages in the paint shop. Dürr’s efficient regenerative thermal oxidation (RTO) process converts polluted exhaust air into clean process air. For this to occur, the process air pollutants must be combustible as fog, vapor, or gas. Once this happens, a mixture of air and one or more combustible pollutants can be converted with the addition of energy. During combustion, the exhaust air reaches such high temperatures that the hydrocarbons it contains bond with oxygen to produce water vapor and carbon dioxide.
The electric Oxi.X RV RTO is unique in the market. The innovative solution combines electrification, the use of renewable energies and compliance with global climate targets and is already in use in more than 600 industrial production processes worldwide. The special feature is, that it can operate on electricity alone, does not require burners, and emits no nitrogen oxides. This CO2-neutral process reduces both the amount of maintenance required and the VOCs contained in the exhaust air in a highly efficient way. The flameless exhaust air purification is extremely flexible thanks to the modular system and can be adapted to structural conditions.
