Fume Treatment Plants
The most visible environmental impact from the production of steel is the air pollution discharged from the plant by means of those scary chimneys emitting the grey and black blooms of fumes. The pollutants from fumes vary from metal solid dusts to organic volatile matters.
The Danieli zero-impact concept together with the sustainability approach force mandatory the application of the most advanced fume treatment technologies for the metal production, for instance, the EAF dust abatement with cyclone and bag filters, the cooling of the high fume temperature (with heat recovery), as well as the treatment of primary gas from BOF belongs to those base technologies offered to metal producers.
The Danieli technologies are able to capture and treat the primary fumes from the furnace roof and the secondary fumes from the canopy hood on the building roof over the furnace shell, as well as the ladle furnace fumes and those from the material handling systems.
The control of the air contaminants is as well provided by reducing them at the source, which makes it unnecessary to use expensive abatement technologies.
Danieli Fume treatment technologies perform and ensure a concentration of dust less than 1 mg/Nm3 at external of the plant, with future target to offer equipment able to reach value less then 0,2 mg/Nm. The emission of dioxins (PCDD-F) and other volatile heavy metals are totally treated and abated with DAS system with the injection of activated carbon. The residual emission of pollutants at downstream of abatement system is less than 0,1 ngTEQ/Nm3, in line with the European legislations.
Furthermore, Danieli is going to perform the NOx treatment by means of selective catalytic materials to guaranty the air emission even for those situations where the quality of scraps is low. The future target is reach zero air emissions with new process, technologies and new bio materials.
The design of FTP by Danieli Environment is optimized with consideration of parameters as the EAF capacity and melting profile, the type of charge, the occupational health and environmental rules, site ambient conditions and the area availability.
Moreover, the Computational Fluid Dynamics simulates the right process and dynamics of the fluids internal and external the production building, it ensures the absence of diffuse-scattered fume emissions from the building to outside.
