Painting and Coatings-Case Study Pollutant Emission Control in Industrial Coating Processes

airprotech supplies technologies and plants for the control of emissions in the Painting & Coatings industries, a variety of solutions suitable for a wide range of applications as industrial painting shop using solvent-based paints and UV type.

airprotech designs and manufacture customized systems for treatment of exhaust gases from processes involving paints such acrylic, vinylic, polyester, phenolic, epoxy, polyurethane. Environmental regulations require the installation of advanced systems for the control of emissions of volatile organic compounds VOCs.

RTO REGENERATIVE
THERMAL OXIDIZERS

Regenerative thermal oxidizers RTO are specifically designed to destroy the pollutants from the process gas through thermal oxidation at high temperature.

RECUPERATIVE
THERMAL OXIDIZERS

Recuperative thermal oxidizers with a main combustion chamber for thermal oxidation at high temperature and integrated heat recovery system.

DIRECT
THERMAL OXIDIZERS

Direct thermal oxidizers destroy the pollutants through thermal oxidation at high temperature, process gas and/or waste organic liquids are directly injected in the combustion chamber.

CATALYTIC
OXIDIZERS

In the catalytic plants the oxidation of organic substances is carried out with lower temperature using high-performance base-metal and precious-metal catalysts.

VOC ROTOR-CONCENTRATORS

airprotech supplies zeolite-based VOC rotor-concentrators that are typically installed in case of low concentration of pollutants and large flow rate.

ADSORPTION ON
ACTIVATED CARBON

Activated carbon is an inert solid adsorbent material used to remove contaminants from process gas streams.

SCRUBBERS AND
WASHING TOWERS

Scrubber and washing towers are used mainly for the removal of volatile organic and inorganic compounds which are water-soluble and using chemical reagents.

WET AND DRY
DEDUSTING

Filtration, dedusting and separation of dust and solid particles from process gas can be performed through wet and dry solution depending on the specific application.
