New milestone reached at Formosa Ha Tinh

Formosa Ha Tinh Steel in Vietnam has reported a successful hot commissioning of its first dry-quenching furnace, further boosting the steelworks’ energy-saving and environmental protection indicators 

CISDI built the coke dry-quenching project on an EPC basis, in addition to providing services to FHS’s master plan, general design and feasibility study. CISDI has also carried out the engineering of the stockyard, and is responsible for blast furnace 1 and 2, gas holders and reheating furnaces.

CDQ is an environmental protection technology which uses low-temperature inert nitrogen to cool down the hot coke. The traditional method is wet quenching with water. The dry process enables the coke’s sensible heat to be recovered and improves the final quality of the coke. In addition, pollution is reduced.

This is Vietnam’s first CDQ project, and is supported by FHS and the Vietnamese government. A second dry-quenching furnace is scheduled to be hot-commissioned in May.

Each dry quenching furnace has been designed for a capacity of 200 tonnes an hour, and will be supported with one 36MW turbo-generator and utilities.

Both furnaces can treat about three million tonnes of coke annually, and generate a maximum of 6x10⁸kWh of power.

The CDQ project is the last of 54 environmental awareness improvements FHS promised the Vietnamese government it would carry out during the construction of the steelworks.
