Alternative sources trialed to replace coke ovens gas
11 July 2023
LIBERTY Primary Steel (LPS) has started post-coke oven operational trials at its Whyalla steelworks as the transition to electric arc furnace-based steelmaking continues.
Following the recent decision to target a September closure for the coke ovens, the trial started on Tuesday 11 July to confirm the use of alternative gas sources to replace the existing coke ovens gas.
During the 24-hour trial, the plant will run solely on the gas from the blast furnace and imported natural gas. This means the coke ovens gas (COG) will be consumed or flared and residents may notice a larger flare than usual over the steelworks.
There may also be some additional steam observed from the top of the Blast Furnace as part of the trial.
LPS Managing Director, Tony Swiericzuk said the gas trials marked a significant milestone in the steelworks operational journey as the GFG Alliance operation explores the process of running the site without COG.
“This trial serves as an opportunity to thoroughly evaluate our readiness and make necessary adjustments to ensure a seamless and efficient production process in the post-coke ovens era,” Tony said.
“We are aiming to sustain operations using alternative gas sources while maintaining our production levels, quality standards, and timely delivery of steel.”
