Other sectors available

The paper industry is renowned for its intensive utilization of water and energy, necessitating innovative pulp and paper industry solutions to address the environmental impacts of its operations. TECNIUM leads in delivering state-of-the-art solutions, ensuring eco-conscious practices and energy efficiency within this sector.

Pulp and paper industry solutions focus on delivering technologies and processes that mitigate the impacts of pulp digestion, bleaching effluents, and other industrial processes before their reintroduction into the mill. These solutions are paramount in handling waste gas flows generated, particularly during the bleaching of paper pulp, which needs meticulous treatment before being released into the atmosphere.

Chlorine dioxide (ClO2) is integral to the paper bleaching process, and it generates waste gas flows that are toxic and corrosive. TECNIUM develops specialized centrifugal fans, designed meticulously to handle such gases. The fans are crafted from materials adapted to the process conditions and are equipped with sealing systems to prevent the leakage of polluted gases, ensuring operational safety and minimal environmental impact.

In the realm of the pulp and paper industry, the shift from using Cl2 to ClO2 was crucial in reducing the formation of organochlorines, dioxins, and tetrachloride furans in effluents. Industrial production of ClO2 is generally produced on-site to minimize transport risks and maintain chemical stability. It is transported to an absorption tower where it dissolves in cold water to produce an aqueous bleach solution.

Given the high toxicity and corrosiveness of chlorine dioxide, facilities necessitate specifically designed safety systems to avoid exposure risks in case of leakage. Hence, the choice of materials is vital to ensure the longevity and reliability of the equipment, emphasizing the importance of specialized solutions that TECNIUM provides.

TECNIUM remains at the forefront in delivering innovative pulp and paper industry solutions, providing centrifugal fans and advanced technologies to both installation providers and end-user’s paper mills. These solutions are tailored to handle the corrosive and toxic gases prevalent in the industry while advocating for environmental stewardship and operational safety.

Our commitment to sustainability and technological advancement continues to drive the development of solutions that align with environmental standards and contribute effectively to the ecological conservation in the pulp and paper industry.

TECNIUM BIO-TR exemplifies efficiency in biotrickling technology, allowing the reconversion of chemical scrubber installations, eliminating reagent consumption, and removing the need for chemical product storage within facilities. This advancement is pivotal in streamlining operations and enhancing sustainability in pulp and paper industry solutions.

TECNIUM-CHEM technology stands out in offering multiple systems for gas treatment and odor control, utilizing water or chemical absorption. It incorporates wet scrubbers, jet venturis, and cyclones, catering to the diverse needs of the pulp and paper industry, ensuring optimal control over emissions and odors.
