Nippon Steel Engineering Co., Ltd. (Representative Director and President: Yukito Ishiwa, Head Office: Shinagawa-ku, Tokyo, hereinafter referred to as "NSE") is pleased to announce that we have been awarded the contract from JFE Steel Corporation (Representative Director and President: Masayuki Hirose Head Office: Chiyoda-ku, Tokyo; hereinafter referred to as "JFE") for design, manufacturing and installation of one unit of Coke Dry Quencher* for West Japan Works (Fukuyama area, Processing capacity: 144 t/h, hereinafter referred to as "CDQ").

This CDQ is to be newly installed for the coke dry-quenching process in association with the introduction of the 6th Coke Oven at West Japan Works (Fukuyama) of JFE. NSE have delivered the similar CDQ for East Japan Works (Chiba) of JFE in 2022 and the high appreciation by JFE regarding NSE's project management capabilities such as acceleration of the planned installation schedule and smooth start-up of the plant, has led to this continuous contract award for the large-scale projects.

The introduction of this CDQ, which contributes to the improvement of the efficiency of energy usage in the steelmaking process, is eligible for subsidy by Sustainable open Innovation Initiative (SII) of Japan.

The contract award will bring the total number of CDQ delivered by NSE group to 170 units. As NSE CDQ plants greatly contribute to the environment through energy-saving and reduction of CO2 emissions, achieved through high operating ratio and highly-efficient power generation, the plants have been highly evaluated by various customers both in Japan and overseas.

NSE will continue to contribute to the development of the iron & steel industry all over the world and the realization of carbon neutrality through supply of CDQ .

*The Coke Dry Quenching Plant (CDQ stands for "Coke Dry Quenching")

The plant cools red hot coke of approximately 1,000°C, which was carbonized in a coke oven using inert gas within the cooling chamber and recovers sensible heat of red-hot coke as steam in the waste heat recovery boiler where previously the sensible heat was diffused. Electricity generated by CDQ is environmentally friendly and clean energy. In comparison with conventional wet quenching plants, it is superior in three ways: (1) less dust generation when cooling coke, (2) less CO2 emissions through power generation by steam, and (3) higher quality coke suitable for use in blast furnaces.
