Abstract

Staklenički plinovi (ugljikov dioksid, metan, dušikov oksid, flourirani plinovi) su plinovi
koji apsorbiraju te re-emitiraju infracrveno zračenje prema Zemlji. Povećanje koncentracije stakleničkih plinova u atmosferi antropogenim djelovanjem dovelo je do potpisivanja Kyoto protokola čiji je cilj stabilizacija koncentracije stakleničkih plinova do razine koja će spriječiti štetni antropogeni utjecaj na klimu. Pošto je metalurška industrija jedna od glavnih emitera stakleničkih plinova, a kako je za proizvodnju željeza, odnosno čelika potrebna velika količina energije ključno je smanjiti emisiju plinova, bilo zbog emisija koje nastaju izgaranjem fosilnih goriva ili emisija koje nastaju samim postupkom proizvodnje željeza odnosno čelika, u tim industrijskim procesima.
Ovaj rad se bazira na jednom od procesa proizvodnje čelika – proizvodnja čelika
elektrolučnim postupkom te je u njemu naveden opis procesa kao i mogućnosti, tj. tehnologije koje bi se mogle primijeniti u tome postupku s ciljem smanjenja emisija CO
2. Uz to u radu je dan primjer koji objašnjava korištenje CO2 mehanizama, omogućenih državama potpisnicama Kyoto protokola, sa svrhom stvaranja kapitala smanjenjem emisija CO2.

Abstract (english)

Greenhouse gas (carbon dioxide, methane, nitrogen dioxide, fluorinated gases) are gasses which apsorb and re-emitate infrared radiation toward planet Earth. Increase in concentration of greenhouse gas in atmosphere lead to signing the Kyoto Protocol which main goal is stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic human induced interference with the climate system. Since
metallurgy is one of the main emitters of a greenhouse gas, due to its emission from
combustion of fossil fuels or emissions regarding a process of production of iron/steel itself,
it is crucial to reduce its emission of CO2.
This paper is based on one of the process use for producing the steel – production in electric arc furnace and it gives a detailed description of mentioned process as well as technologies which can reduce its emission of CO2. It also gives an example explaining benefits from reducing emission of CO2 using mechanisms given by Kyoto Protocol.
