20.500.12556/RUL-187789 Ocenjevanje tveganj pri skladiščenju kemikalij, potrebnih za proizvodnjo fenolne smole Risk assessment of stored chemicals required for the production of phenolic resin Magistrsko delo obravnava varnost skladiščenja nevarnih kemikalij pri proizvodnji fenolne smole ter oceno vpliva nenamernega izpusta metanala, fenola in metanola na obrat in okolico. V teoretičnem delu je predstavljen zakonodajni okvir ter osnove analiz tveganja, s poudarkom na kvantitativni oceni tveganja in metodi HAZOP. Opisano je tudi modeliranje posledic izpustov s programoma ALOHA in PHAST ter primeri nezgod s omenjenimi kemikalijami. V empiričnem delu je obravnavam raztopino, ki vsebuje 55 % metanala, fenol in metanol. Na podlagi podatkov v varnostnih listih so bile identificirane in analizirane njihove nevarne lastnosti. Izvedena je bila HAZOP analiza skladiščenja ter ocena tveganja z matriko tveganja. Izbrani so bili scenariji, za programski opremi ALOHA in PHAST, z nizko verjetnostjo in hudimi posledicami, ki so bili modelirani za poletne in zimske razmere. Rezultati kažejo, da največje tveganje predstavlja izpust metanala, saj lahko vplivi segajo več kilometrov izven območja obrata. Fenol zaradi nizkega parnega tlaka predstavlja predvsem lokalno nevarnost, medtem ko pri metanolu večje tveganje za širšo okolico predstavlja njegova strupenost, ne pa toplotni učinki ob morebitnem požaru. Ugotovljeno je bilo, da skladiščenje obravnavanih snovi predstavlja tveganje za večjo industrijsko nezgod z možnimi hudimi posledicami za zaposlene in deloma tudi za okoliško prebivalstvo. Predlagani so bili tehnični, organizacijski in preventivni ukrepi za zmanjšanje verjetnosti izpusta in omejitev posledic. Primerjava programov je pokazala, da je ALOHA primerna za osnovne ocene tveganja, PHAST pa za zahtevnejše in natančnejše analize. This master’s thesis examines the safety of hazardous chemical storage in phenolic resin production and assesses the impact of accidental releases of methanal, phenol, and methanol on the facility and its surroundings. The theoretical part outlines the legislative framework and the fundamentals of risk analysis, with emphasis on quantitative risk assessment and the HAZOP method. Consequence modelling using ALOHA and Phast software is also described. The empirical part focuses on solution, that contains 55 % formaldehyde, phenol, and methanol. Based on safety data sheets, their hazardous properties were analysed, a HAZOP study was conducted, and risks were evaluated using a risk matrix. Scenarios with low probability but severe consequences were modelled for summer and winter conditions in ALOHA and Phast. The results show that formaldehyde release represents the highest risk, with potential impacts extending several kilometres beyond the facility. Due to its low vapour pressure, phenol mainly poses a local hazard, whereas for methanol, toxicity presents a greater risk to the surrounding area than thermal radiation from potential ignition. The study concludes that the storage of the analysed substances poses a risk of a major industrial accident. Technical and organizational measures were proposed to reduce both the likelihood and consequences of such events. ALOHA proved suitable for preliminary assessments, while Past is more appropriate for detailed analyses. ocena tveganje HAZOP metanal fenol metanol ALOHA Phast risk assessment HAZOP methanal phenol methanol ALOHA Phast true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-09-14 13:25:03 2026-09-14 13:25:08 2026-09-16 03:48:52 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 25385 Petek_Ana_-_Ocenjevanje_tveganj_pri_skladiscenju_kemikalij,_potrebnih_za_proizvodnjo_fenolne_smo.pdf Petek_Ana_-_Ocenjevanje_tveganj_pri_skladiscenju_kemikalij,_potrebnih_za_proizvodnjo_fenolne_smo.pdf 1 9C525D52D3B27BFB5D0451090C0F329B 1ec422002fd21ec924a52da8b27cff88661b5e224ccb3f52aa4ec3168280c7cc e8ea9bfe-b02e-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247544 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
