MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202617013011 A) filed by Sms Group S. P. A., Udine, Italy, on Feb. 6, for 'steel plant with electric arc furnace.'
Inventor(s) include Bertolissio, Arrigo; and Lanari, Andrea.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a steel plant (1) comprising at least one electric arc furnace (10) and a fume collection and treatment system (100) adapted to collect and treat gaseous emissions produced by steel plant (1). Said fume collection and treatment system (100) comprises : a primary suction line (110) fluidically connected to the electric arc furnace (10) to suck the fumes generated in said electric arc furnace (10); at least a first secondary suction line (120) adapted to ventilate the environment surrounding the electric arc furnace (10) by means of at least one fume hood (120a). Along said primary suction line (110) there are arranged in sequence starting from the electric arc furnace (10) at least: - a post-combustion chamber (111), a fume cooling apparatus (112), and a CO2 capture apparatus (113). The first secondary suction line (120) flows into the primary suction line (110) downstream of the CO2 capture apparatus or discharges into the atmosphere separately from said primary suction line (110). The primary suction line (110) comprises a recirculation line (130) to recirculate at least part of the gaseous emissions to the post-combustion chamber (111). The recirculation line (130) fluidically connects the section of the primary suction line (110) between the cooling apparatus (112) and the CO2 capture apparatus (113) with the section of the primary suction line (110) upstream of the post-combustion chamber (111). The plant (1) comprises a control system (132, 133) of the recirculation flow rate of the gaseous emissions to the post-combustion chamber (111) configured to adjust the recirculation flow rate at a sufficient value to reduce the entry of comburent air to the post-combustion chamber to the stoichiometric minimum, maintaining the temperature in the post-combustion chamber within a predetermined temperature range."
The patent application was internationally filed on Aug. 06, 2024, under International application No.PCT/IB2024/057608.
