Abstract

Emitiranjem stakleničkih plinova njihova koncentracija u atmosferi raste što uzrokuje efekt staklenika, odnosno klimatske promjene koje imaju sve veći utjecaj na život ljudi. U ovom radu prikazana je analiza mjera za smanjenje emisija stakleničkih plinova u odabranom industrijskom postrojenju korištenjem alternativnih goriva. Kao industrijsko postrojenje odabrana je energetski intenzivna cementna industrija koja emitira velike količine stakleničkog plina CO2. U prvome dijelu rada opisana je cementna industrija te procesi koji se odvijaju kako bi se iz sirovine dobio konačan proizvod – cement, te su pritom opisani izvori štetnih i stakleničkih plinova i načini na koji se oni nastoje smanjiti. Opisane su i mogućnosti smanjenja emisija koje se temelje na poboljšanju energetske učinkovitosti i mogućnosti smanjenja emisija uporabom alternativnih goriva s naglaskom na gorivo iz otpada RDF/SRF.

Drugi dio rada sadrži proračun potencijala smanjenje stakleničkih plinova u cementnoj industriji uporabom RDF/SRF goriva čiji su sastav i svojstva određeni na temelju komunalnog otpada Republike Hrvatske. Prikazan je izračun udjela biorazgradive komponente, emisijskog faktora i ogrjevne vrijednost alternativnog RDF/SRF goriva. Potencijal smanjenja stakleničkih plinova prikazan je na 3 scenarija u kojemu su različiti udjeli potrebnog konvencionalnog goriva zamijenjeni RDF/SRF gorivom te je izrađena ekonomska analiza potencijalnih ušteda na troškovima goriva i troškovima dozvola za emitiranje u sklopu EU ETS sustava.

Abstract (english)

By emitting greenhouse gases, their concentration in the atmosphere increases, which causes the greenhouse effect and climate change, which has an increasing impact on people's lives. This paper presents an analysis of measures to reduce greenhouse gas emissions in a selected industrial plant using alternative fuels. The energy-intensive cement industry, which emits large amounts of greenhouse gas CO2, was chosen as the industrial plant. The first part of the paper describes the cement industry and the processes that take place to obtain the final product from the raw material – cement and describes the sources of air pollutants and greenhouse gases and the ways in which they are reduced. Possibilities of reducing emissions based on improving energy efficiency and possibilities of reducing emissions using alternative fuels with an emphasis on RDF/SRF waste fuels are also described.

The second part of the paper contains a calculation of the potential of reducing greenhouse gases in the cement industry using RDF/SRF fuels whose composition and properties are determined based on municipal waste of the Republic of Croatia. The calculations of the share of biodegradable component, emission factor and calorific value of alternative RDF/SRF fuel are presented. The potential reduction of greenhouse gases is shown in 3 scenarios in which different shares of the required conventional fuel are replaced by RDF/SRF fuel and economic analysis of potential savings on fuel costs and emission allowance costs within the EU ETS system is made.
