Tata Steel sets up largest coke cooling unit at Kalinganagar

Tata Steel has set up India's largest coke dry quenching (CDQ) facility capable of handling 200 metric tonnes of the hot fuel per hour at its greenfield Kalinganagar steel plant in Odisha.
CDQ is a heat recovery system to cool the hot coke from ovens.
Nippon Steel and Sumkin Engineering (NSENGI) of Japan was the supplier and technology partner of the CDQ system and the project was executed by Essar Projects, Tata Steel said in a statement.
Compared to conventional wet quenching, CDQ offers advantages such as reduction in dust emission and improvement of coke quality.
This technology, the company said, "would help in abating climate change by reduction in CO2 emission to the extent of 0.11-0.14 tonnes per tonne of coke and reduction in dust emission to the tune of 300-400 grams per tonne of coke".

It also cuts down dependence on natural resources for energy generation. Other advantages include saving a significant amount of water, which is getting scarce, the company added.
