Abstract

Diplomsko delo obravnava problematiko pri ravnanju z odpadnimi olji. Uvodoma je predstavljena splošna razvrstitev olj glede na izvor, kar je temeljna problematika dela, saj so zaloge osnovne surovine (fosilnih goriv) omejene, oziroma so s trenutnimi tehnologijami pridobivanja vedno težje dostopne. Podana je zakonodaja na področju Slovenije in EU, ki opredeljuje zbiranje skladiščenje in odstranjevanje odpadnih olj. Kot jedro dela so predstavljene najpogostejše možnosti odstranjevanja, ki so prečiščevanje, sežig in rerafinacija. Podrobneje sta predstavljena načina prečiščevanja in rerafinacije. Na podlagi dejstva, da je rerafinacija za dano problematiko okolju najbolj prijazna tehnologija, je bila na osnovi laboratorijskih analiz opravljena primerjava svežih in rerafiniranih olj, ki je pokazala, da je kvaliteta le teh primerljiva z svežimi baznimi olji. Vendar pa ni primerljiva le njihova kvaliteta, temveč tudi cena, ki je danes odločilni faktor pri izbiri surovin pri proizvodnji. Zaradi odličnega slovesa in konstantnih kvalitet svežih baznih olj se, kot kaže, rerafinirana olja ne bodo uveljavila vse dokler ne bodo izrazito cenejša od svežih baznih olj ali pa bo njihova uporaba subvencionirana s strani države.

Secondary title:	Modern technologies of waste oil management
Secondary abstract:	The diploma work addresses the issue of waste oil management. The stocks of raw material for oil production (fossil fuels) are becoming difficult to access with current technologies used and are thus limited. As this represent a fundamental part of the problem, a general classification of oils, according to their origin, is presented at the beginning. The legislations of Slovenia and EU, which defines the collection, storage and disposal of waste oils, are studied. In the main part, refining, incineration and rerefination, as most frequent disposal options, are presented. Moreover, the methods of purification and rerefination are explored in detail. Based on the fact, that the rerefination is the most environmental friendly answer to our problem, a laboratory analysis and comparison between virgin oils and rerefined oils was conducted, which has revealed that the qualities of rerefined oils are comparable to virgin ones. However, it is not only the quality that is important, but it is also the price, which is nowadays a crucial factor when selecting raw materials in oil production industry. Due to the excellent reputation of virgin base oils and their consistent quality, the rerefined oils will not gain their prominence until they are distinctly less expensive or their use is subsidized by the state.
