Russian Pipe Metallurgical Company TMK’s Pervouralsk Novotrubny Plant, PNTZ, has begun to upgrade equipment for air purification at production sites. Modern gas and dust collecting plants of three types with a filtration coefficient from 85 to 99% were put into operation in three workshops of PNTZ. Three installations were launched in the pipe drawing shop, each with a capacity of up to 15,000 cubic meters per hour. Fully automated equipment cleans the air from solid particles formed during the production process, settles them on the filter walls, places them in sealed receiving bins, and then returns the cleaned air to the working room. The collected dust is disposed of in a special landfill in accordance with all environmental standards. In two other workshops, three more units were launched, which also guarantee a high degree of dust removal and, at the same time, do not provide for the return of purified air to the working area.The new equipment is designed with the best available technology in mind, which minimizes dust formation, eliminates emissions into the atmosphere, improves working conditions for employees, as well as obtain an economic effect by reducing electricity consumption. In the future, it is planned to equip five more workshops with similar efficient air purification systemsEarlier, PNTZ replaced the bag filters of gas treatment facilities - the units allow capturing 99.9% of solid particles in the process gases generated during production, ensuring their purification in accordance with Russian and European environmental standards. Also, the enterprise has installed an automated control system for atmospheric emissions, which continuously analyzes the maximum permissible concentration of emissions of nitrogen oxide and dioxide, carbon monoxide, sulfur dioxide, suspended solids, volume fractions of separated water, oxygen, temperature, absolute pressure, speed and flow rate of flue gases.
