Air Products South Africa has once again proven its market leadership when it comes to finding innovative solutions to industrial challenges.
The company has recently designed and implemented a new way of mixing gases using thermo-compressor technology, and as part of ongoing trials has successfully commissioned the first station of its kind at ArcelorMittal’s Newcastle operations.
Ian Gorin, Process Engineering Manager at Air Products South Africa, explains, “The problem was that the mill required a higher pressure gas than what was available from the blast furnace gas. Instead of the traditional method of using a booster compressor powered by electricity, we designed a gas thermo-compressor. This system controls and modulates the gas mix ratio to give exact calorific value as required by the customer.”
“To compress the blast furnace gas by 25 kPa (according to the design flow rate) would have required a blower consuming 145kW of power,” Gorin continues. “The major benefit of the gas thermo-compressor is that it utilises zero electrical energy which obviously translates into significant cost savings for the customer.”
