REIA Report for the Proposed Mini Integrated Steel Plant
Chapter – 11

CHAPTER –XI
SUMMARY
1. This expansion project envisages setting up of 120,000 TPA Sponge Iron, 1,62,000 TPA
Ingots/ Billets, 1,05,000 TPA Rolled products, Ferro alloys of 25000 TPA and 48 MW
electricity through WHRB & FBC routes. The proposed expansion will be taken-up in the
existing plant premises only.
2. The flue gases from the rotary kilns will be pass through Waste Heat Recovery Boiler and
after heat recovery the flue gases will pass through state-of-the-art ESP to bring down the
particulate matter in the exhaust gases to within 50 mg/Nm3 and will be discharged into the
atmosphere through a combined stack (Twin flues) of 60 m height. The secondary fugitive
emissions from the SMS will be treated in a fume extraction system and will be discharged
into the atmosphere through a stack of 30 m height. The gases from the FBC boiler will be
treated in an ESP to achieve < 50 mg/Nm3 and will be discharged into the atmosphere
through a stack of 72 m height for effective dispersion of emissions into the atmosphere The
resultant Ground Level Concentrations of SO 2 , NO X & SPM in the post expansion project
scenario are within the National Ambient Air Quality Standards (NAAQS). Hence there will
not be any adverse impact on air environment due to the proposed expansion project.
3. Interlocking system will be provided to ESP in such a way that , when the particulate matter
in the exhaust gas exceeds the norms the feed to raw material will stop and thereby no
production in the unit. The unit will restarted only when the air pollution control system is
able to comply with the norms.
4. Energy meters will be provided to air pollution control systems to ensure continuous
operation of the control systems.
