The conventional process for neutralizing solvent gases is thermal aftertreatment. For this purpose, the gases contained in the exhaust air are concentrated and then burned with the addition of natural gas. Thermal post-treatment thus requires high energy input and in turn produces pollutants.
In the case of pure solvent exhaust air, e.g. from printing plants, solvents can also be recovered from the exhaust air.
oxytec replaces the energy-consuming thermal post-treatment by photolysis oxidation with UV ozone. The combination of direct exposure to UV light and the free radicals generated by UV light achieves a high effect. In individual cases, it may make sense to supplement the process with our wet scrubbers or to rely on the even more effective plasma technology, which we are the only company to also offer for the industry’s large line cross-sections.
