TMK launches innovative air treatment units at PNTZ

A project to replace shop-floor air treatment units has been launched at TMK’s Pervouralsk Pipe Plant (PNTZ). Three types of modern dust control and gas cleaning units with filtration efficiency ranging from 85% to 99% have been commissioned at three PNTZ’s shops.

Three units have been launched in the tube drawing shop, with a capacity of up to 15,000 m³/h each. Fully automated units clean the air of solid particles generated during the production process, settle them on the filter walls, place them in airtight receptacles, and return the cleaned air to the production area. The collected dust is taken to a dedicated landfill, in line with all environmental regulations. Three more units launched in two other shops also ensure highly efficient dedusting, without returning the cleaned air to the production area.

Vladimir Toporov, PNTZ’s Managing Director, said: “Occupational safety, the health of our employees, and the well-being of local residents in our operating regions are strategic priorities for TMK entities. PNTZ is implementing a long-term environmental program comprising, in particular, measures aimed at improving the air quality. The new equipment has been developed based on the best available technology to minimize dust generation, eliminate air emissions, improve working conditions, and achieve economic benefits by reducing energy consumption. In the future, we intend to equip five more shops with similar efficient air treatment systems.”

Previously, PNTZ replaced bag filters in gas cleaning units to enable them to capture 99.9% of particulate matter generated by process gas production, in line with Russian and European environmental standards. In addition, an automated air emission control system has been installed at the plant, which continuously analyzes emissions for the maximum permissible concentrations of nitrogen oxide and dioxide, carbon monoxide, sulfur dioxide, suspended solids, volume fractions of separated water, oxygen, temperature, absolute pressure, and speed and flow rate of flue gases.
