Ostrava, 11 June 2019 鈥� ArcelorMittal Ostrava, member of the Liberty Steel group, has launched a new deacidifier and ammonia disperser, which are part of the desulphuring process of coke oven gas at coke plant. 天博体育官方网站 device had been in operation since 1998 and was in need of an overhaul. 天博体育官方网站 investment worth of CZK 107 million, together with installation of a new conversion within the fine sulphide scrubbing section, has substantially contributed towards the desulphuring technology modernisation as it enables to lower content of sulphides in the coke oven gas below 300 mg/m3. 天博体育官方网站 revamp took place in full operation of the mill and it took 8 months.

鈥�New technologies help us reduce emissions of sulphide to less than 300mg. This is 40 % less than the emission limit based on the BAT, best available technology standards,鈥� says Kamil Ki膷mer, head of the coke plant at the Ostrava steel mill.

Coke oven gas, originating during the process of coke production, finds further use as fuel for other operation processes at the steel mill while saving non-renewable energy resources. Prior to its use as replacement for natural gas, raw coke oven gas has to be rid of undesirable substances such as ammonia and sulphide. This is achieved by processing the gas in wet hydrogen sulphide and ammonia scrubbers which also include the newly installed deacidifying and ammonia dispensing technologies that ensure regeneration of the scrubbing solutions.

鈥�Investments in lowering the content of sulphide at coke plant will lead to instant cuts in SO2 emissions during all operation processes that use the gas as fuel 鈥� at power plant, rolling mills or hot blast stoves for blast furnaces,鈥� adds Ki膷mer.
