Abstract
Hidrokrekiranje je tehnološki proces pretvorbe teških naftnih frakcija u visokokvalitetne lakše frakcije poput kerozina i dizela, a uspješnost procesa ovisi o pravovremenom i preciznom praćenju i optimizaciji procesnih parametara. Diplomski rad sagledava ključne procesne varijable Hidrokreking postrojenja Rafinerije nafte Rijeka te njihov utjecaj na učinkovitost katalizatora i kvalitetu proizvoda. Eksperimentalni dio rada uključuje laboratorijske analize sirovina i produkata poput simulirane destilacije, određivanja količine sumpora, bromnog broja, gustoće i indeksa refrakcije. Analizirana je i povezanost tih rezultata s procesnim parametrima kao što su razlika temperature u katalitičkim slojevima i masena prosječna temperatura katalizatora (WABT-a). Dobiveni rezultati ukazuju na povezanost procesnih parametara s kvalitetom produkata i stabilnošću katalizatora. Uočeno je da pad temperature u četvrtom sloju katalizatora i sniženje indeksa refrakcije teške šarže odražavaju promjene u sastavu sirovine i u reakcijskoj učinkovitosti. Kontinuirano praćenje parametara poput WABT-a, optimizacija reakcijskih uvjeta i kvalitetna analiza sirovina mogu značajno doprinijeti poboljšanju učinkovitosti procesa.
Abstract (english)
Hydrocracking is a technological process that converts heavy petroleum fractions into high-quality lighter fractions such as kerosene and diesel. The success of the process depends on timely and precise monitoring and optimization of process parameters. This thesis examines the key process variables of the Hydrocracking Unit at the Rijeka Oil Refinery and their impact on catalyst efficiency and product quality. The experimental part of the thesis includes laboratory analyses of feedstocks and products, such as simulated distillation, sulfur content determination, bromine number, density, and refractive index measurements. The relationship between these results and process parameters, such as the temperature differential across catalytic beds and the weighted average bed temperature (WABT) of the catalyst, was also analyzed. The results indicate a correlation between process parameters, product quality, and catalyst stability. A drop in temperature in the fourth catalytic bed and a decrease in the refractive index of the heavy feedstock were observed to reflect changes in feedstock composition and reaction efficiency. Continuous monitoring of parameters such as WABT, optimization of reaction conditions, and quality analysis of feedstocks can significantly contribute to improving process efficiency.catalytic hydrocracking, catalyst, hydrogenation, desulfurization
