Abstract

Sve djelatnosti koje u proizvodnim procesima emitiraju stakleničke plinove (definirano Uredbom o načinu trgovanja emisijskim jedinicama stakleničkih plinova), kao što su CO2, N2O, PFC, itd. moraju podnijeti "Izvješće o godišnjim emisijama iz postrojenja". U izvješću izvori emisija i materijali trebaju biti točno identificirani te izračunata količina ispuštenog CO2. Budući da industrija proizvodnje čelika zahtijeva visoku temperaturu, koja se dobiva pomoću raznih goriva (prvenstveno fosilnih goriva i električne energije), oni imaju obvezu podnošenja "Izvješća o godišnjim emisijama iz postrojenja."
U ovom radu opisan je elektropećni postupak za proizvodnju čelika u čeličani ABS SISAK d.o.o. te je izračunata godišnja emisija CO2 za 2015. godinu. Za potrebe izračuna emisije CO2 dan je prikaz svih sirovina koje sadrže ugljik, njihov sadržaj ugljika i iznos utrošenih sirovina. Izračunata je emisija od 18.382 t CO2 za 2015. godinu. Da bi se osigurala vjerodostojnost podataka, izvješće obavezno prolazi postupak verifikacije od strane ovlaštenog verifikatora koji isto provjerava i odobrava (sukladno Uredbi EU br. 600/2012).

Abstract (english)

All industries which have in their manufacturing process greenhouse gas emissions (defined by the Regulation on greenhouse gas emission units trading, Official gazette 69/12), such as CO2, N2O, PFC, etc. must submit a "Report on annual emissions from plant". In report emission sources and materials should be exactly identified and the amount of emitted CO2 calculated. Since the industries of steel production requires a high temperature, which is obtained from a variety of fuels (primarily fossil fuel or electricity), they have obligation to submit "Report on the annual emissions from the plant."
In this paper, the electric arc furnace process for producing the steel in plant ABS Ltd. Sisak has been described and the annual CO2 emission for Year 2015 has been calculated. For calculation of CO2 emission, all raw materials containing carbon, their carbon content and amount of spent raw materials were shown. Calculated CO2 emission for year 2015 was 18382 t CO2. To ensure the credibility of the data, the report has to undergo verification procedure by an authorized verifier for verification and approval (according to Regulation EU no. 600/2012).
