The metals industry plays a central role in our economy and is directly linked to many industrial activities, many branches and sectors of the metals industry are more and more growing their environmental consciousness. airprotech has a long experience in designing and supplying emissions control systems in different applications for production and transformation processes of ferrous and non-ferrous metals. airprotech delivers advanced solutions for a wide range of fields like automotive, brake pads production, aluminum foil lamination, foundry and galvanization plants.
Regenerative thermal oxidizers RTO are specifically designed to destroy the pollutants from the process gas through thermal oxidation at high temperature.
Recuperative thermal oxidizers are composed by a main combustion chamber for thermal oxidation of pollutants at high temperature with an integrated heat recovery system.
Direct thermal oxidizers are composed of a combustion chamber in which the process gas is injected directly and the pollutants are oxidized and neutralized through combustion.
In the catalytic plants the oxidation of organic substances is carried out with lower temperature using high-performance base-metal and precious-metal catalysts.
Activated carbon is an inert solid adsorbent material used to remove contaminants from process gas streams.
SCRUBBERS AND WASHING TOWERS
Scrubber and washing tower plants are used for the removal of volatile organic VOC and inorganic VIC compounds, using water and additional chemical reagents for the abatement of pollutants.
WET AND DRY DEDUSTING
Dust separation from process gas can be performed through wet and dry solution depending on the specific application. Venturis and sieve tray scrubbers are used to remove solid and sticky particles from exhaust gas streams through the interaction with water. Static filters, bag and cartridge filters are used for separation and collection of dry dust and particles.
SCR DENOX PLANTS
The most effective process to eliminate nitrogen oxides NOx is the selective catalytic reduction SCR composed by special catalytic elements operating in combination with injection of ammonia or urea.
LAMINATION OIL RECOVERY SYSTEMS
High efficiency systems with double action in one single plant for the ventilation of aluminium rolling mills and the recovery of the lamination oil.
