Cost effective installation for US Steel
December 12, 2011
Hatch has been retained by US Steel to provide EPCM services at its Gary Works facility in Gary, Indiana, USA.
Hatch will provide engineering, procurement and construction management services for the installation of Stove Oxygen Enrichment (SOE) technology to the No. 8 Blast furnace hot blast delivery system. The use of SOE will offset the purchase of natural gas for enrichment of the blast furnace gas fuel used to heat the stoves.
Stove Oxygen Enrichment technology is designed to lower the operating costs of blast furnace stoves. In blast furnace stoves, some sweetening fuel gas, such as natural gas or coke oven gas, is usually mixed into the blast furnace gas to raise its heating value and achieve the desired blast temperatures. SOE technology, which enriches the oxygen content of the combustion air stream, can provide the same desired blast temperature without the need for sweetening fuel gas.
From the installation, US Steel will be able to optimize fuel costs, offsetting the fluctuating costs of natural gas and oxygen.
The project began in September 2011. Installation is scheduled for completion by the end of 2012. Offices in Hamilton and Pittsburgh are participating in the project.
