Air Purification in the Wood and Paper Industries

Air Purification in the Wood and Paper Industries

Exhaust air purification systems for the woodworking and paper industry

When manufacturing products from wood, paper, and cardboard, chemicals specific to the given field are used. Volatile components, such as formaldehyde, are released from these into the air. Additionally, the inks used in the printing and packaging industries contain solvents (BTEX).

The financial expenses for air pollution control measures, which relates to the given problem, are a great burden for these companies.  High demands are placed on the purification system, because nearly all company emissions are organic and composed of compounds containing tar, oils, or solvents. Moreover, they exhibit strong odor pollution.

Afterburning is often used to lower emissions, though it is marked by high energy costs.

UV-C ozone technology is an exhaust purification technology that significantly reduces energy consumption. A modular system for exhaust air purification, it efficiently eliminates tar, oil, and solvents – as well as odors.

    Process – The process is composed of several system components

    • An air scrubber
    • A condenser
    • A UV-C ozone exhaust purification system
    • The reaction path
    • A catalytic converter

    Advantages:

    • Low operating costs – in comparison with the common method of afterburning, up to 80% is saved on energy costs
    • The greater level of separation efficiency offered by oxytec’s exhaust purification system ensures compliance with emission threshold values in accordance with TA Luft and VDI standards.
    • Low maintenance costs – oxytec’s exhaust purification systems are not subject to thermal degeneration.
