JSW Steel Ltd have signed a contract to modify their existing Midrex Direct Reduction (DR) Plant located at JSW-Dolvi Works (formerly JSW Ispat, Ltd) to use coke oven gas (COG) to supplement its natural gas supply for production of direct reduced iron
Strategically located on India’s west coast in the state of Maharashtra, the JSW-Dolvi Works 1.0Mt/y Midrex plant began operation in 1994 producing cold DRI for use on site using 100% natural gas. With the continuing escalation of natural gas prices, combined with infrequent availability of consistent gas supply in India, JSW Steel has looked to Midrex to convert the unit to use coke oven gas to create better sustainability for the plant and overall site.
The project, scheduled to be completed within 16 months or less, will use COG as a supplement to its natural gas intake so that the DR plant will be able to efficiently operate under a wide range of operating parameters, offering maximum flexibility to JSW Dolvi Works. The COG will be supplied from the coke batteries at Dolvi used to produce coke for the 2Mt/y blast furnace there.
JSW Dolvi Works is owned by JSW Steel Ltd. (India's largest privately owned steel company) and has a long history of implementing technological enhancements to boost productivity, lowering costs and improving environmental performance. These include the induction of an automated Lime Coating System for pellet and an Oxygen Injection System for the shaft furnace.
