20.500.12556/DKUM-80547 Pregled in ocena potenciala energetske integracije med različnimi industrijskimi podsektorji diplomsko delo univerzitetnega študijskega programa I. stopnje Overview and assessment of the potential for energy integration of various industrial subsectors Diplomsko delo se osredotoča na analizo procesnih tokov železarske in jeklarske industrije, rafinerij, proizvodnje amonijaka in proizvodnje cementa ter apna, v Združenih državah Amerike. Ti predstavljajo podsektorje, ki imajo znatno porabo in višek primarnih virov energije. Cilj diplomskega dela je bil, da določimo kje prihaja do največjih energijskih izgub ter raziskava vpliva uvedbe toplotne integracije znotraj posameznega sektorja in tudi integracije med sektorjiali kombinaciji dveh. Najprej smo izvedli analizo zgodovinskih porab energij v posameznih sektorjih. S preučevanjem primarnih virov energije ter njihovih tokov doprinesemo k razumevanju sistema rabe energije ter nastajanja izgub po posameznih sektorjih. Potencial uvedbe toplotne integracije smo določili na podlagi najbolj pogosteje uporabljene tehnologijo znotraj posameznega podsektorja in njihovih procesnih tokov. Potencial toplotne integracije smo ocenili z uporabo tehnologije uščipa, ki smo ga izvedli ter rezultate grafično predstavili s pomočjo programa Microsoft Excel in postavljenih izračunov za uščipno tehnologijo. Ugotovili smo, da z uvedbo toplotne integracije, v posameznih podsektorjih oziroma v povezavi dveh, pridemo do velikih prihrankov energije. Nadalje smo s pomočjo sestave energijskega miksa ocenili izpuste CO2eq v že omenjenih podsektorjih. The work focuses on the analysis of process flows of the iron and steel industry, refineries, ammonia production, and cement and lime production in the United States. These represent sub-sectors that have significant consumption and surplus of primary energy sources. The aim of the work was to determine where the largest energy losses occur and to investigate the impact of introducing Heat Integration within an individual sector and also integration between sectors or a combination of the two. We first performed an analysis of historical energy consumption in individual sectors. By studying the primary energy sources and their flows, we can contribute to the understanding of the energy use system and the generation of losses by individual sectors. The potential for the introduction of Heat Integration was determined on the basis of the most frequently used technologies within an individual subsector and their process flows. The potential of Heat Integration was assessed using Pinch Technology, and the results were presented graphically using Microsoft Excel and set calculations for Pinch Tchnology. We found that by introducing Heat Integration in individual subsectors or in combination of two, we can achieve large energy savings. Furthermore, using the composition of the energy mix, we estimated CO2eq emissions in the already mentioned subsectors. industrijski sektorji toplotna integracija uščipna tehnologija energijski sistem CO2 emisije industrial sectors heat integration pinch technology energy system CO2 emissions true true false [A.
