at Toranagallu, Karnataka. This gas is exported to the Direct Reduction Plant. They are also
replacing some of their natural gas consumption at Dolvi, Maharashtra. These are very recent
developments. The simplified flow sheets indicate that these plants use oxygen in place of air.
These technologies were provided by Midrex Technologies [160].
Tata Steel has developed a technology to produce hydrogen from the quenching section by
Thermo Splitting of water. This is a novel technology. This could provide a good source for
hydrogen. [76]. Currently, they are probably using this internally and looking for a partner for
commercial exploitation of their hydrogen production technology, in 2011. [159]
With the recent trend of modernizing of large steel plants with Direct Reduction and Gasification
with oxygen, there is some possibility of production of Methanol or DME with proper selection
of available feedstocks as well as integrating with biomass gasifiers or digesters. This will
require careful consideration for case to case basis to ensure availability of adequate quantity
of gas at right quality.

It is known that the steel plants are struggling with reduction of carbon dioxide emission. If
hydrogen could be produced within the plant, probably it will be one of the best options to put
up a demo plant for CO hydrogenation to methanol. This will not only reduce the emission
2
burden but also avoid hydrogen handling and transportation. Even if the carbon dioxide
utilization is not feasible, this hydrogen could be easily reacted with blast furnace gas or even
with the available coke oven gas to fix the hydrogen. With the methane present in coke oven
gas there is a good possibility of using some carbon dioxide for reforming of this methane.
Such possibilities also could be explored.

OFF GASES FROM CEMENT INDUSTRY IN INDIA

India is the 2nd largest cement producer in the world. The current installed capacity of more
than 380 MTPA with production of about 272MTPA. The average Kiln Capacity is about 4500
TPD. Approx. 7% of India’s man-made CO emissions come from this industry. The current
2
focus is waste heat recovery and reduction of GHG emission [72]. As such, not much gas
having useful calorific value is available from the cement industry off gases.
