Coke oven gas is a byproduct that forms during the production of coke from coal in coke ovens. This order marks a significant milestone, as it is the first of its kind in India, setting a precedent for the industry's move towards sustainable steel production.

Paul Wurth COG Injection Technology is a breakthrough innovation that aims to reduce the coke rate and consequently the carbon footprint of the blast furnace operation. By utilizing the chemical potential of COG, the process can save around 0.65kg of coke for each kilogram of COG injected, which considerably reduces the OPEX cost and significantly improves the CO2 footprint. Paul Wurth’s COG injection technology is designed to ensure the safe and reliable injection of the highly toxic and explosive COG into the blast furnace through the tuyeres using specialized lances.

The comprehensive scope of supply for this project includes plant engineering, supply of all process equipment including compressor station, electrics and automation ensuring an integrated approach to the implementation of this technology.

To optimize the supply of gas to the blast furnace, selection of adequate compressor technology as well as the control of the temperature range are crucial success factors to guarantee smooth operation of the plant. The advanced Paul Wurth automation system assures this smooth operation and at the same time, guarantees plant safety implementing for each injection line fully automatic flushing, flow monitoring and lance cooling.

The project is expected to be commissioned by Q1 2026 and will be completed within 25 months.

Tata Steel and SMS group share a longstanding partnership, with SMS group being recognized as an integrated system supplier for its Blast Furnace Technology and a pioneer in solutions for CO2 emission reduction with solutions suited to the need of the customer.

India has set the target to achieve net zero by 2070. The implementation of this technology is not just a record-breaking feature for India but also a significant step towards achieving net zero emissions. SMS group's leadership in this field is further highlighted by the nomination of their COG injection project in Gijon for the prestigious Steelie award by the World Steel Association (WSA) in 2022.

Subodh Pandey, Vice President, Operations - Tata Steel Meramandali, NMB+Graphene, Tata Steel, said: “The implementation of this technology is not only a record-setting achievement for India but also a strategic move towards meeting the country's goal of net zero by 2070. As we lay the groundwork for a greener future, this collaboration with SMS group is not just a milestone for us but a beacon for the entire Indian steel industry. By adopting cutting-edge technologies like COG injection, we are not only reducing our carbon footprint but also setting a new standard in environmental stewardship while enhancing our operational efficiency and competitiveness in the global market.”

Rene Gaiola, Head of Injection Technologies at SMS group: ”We are fully committed to #turningmetalsgreen and believe that the successful implementation of this project will only be the start of a long-term partnership with Tata Steel to implement further steps of decarbonization of Tata’s Meramandali Steel plant.”
