Abstract:V diplomskem delu obravnavamo možnost trajnostne proizvodnje sintetičnega metanola iz ogljikovega dioksida in vodika, pridobljenega z elektrolizo vode z uporabo obnovljivih virov energije. Cilj naloge je bil s pomočjo programskega paketa Aspen Plus razviti računalniški model procesa sinteze metanola ter analizirati vpliv ključnih obratovalnih parametrov na učinkovitost procesa. V teoretičnem delu so predstavljeni viri in metode pridobivanja vodika, možnost zajemanja CO2 ter lastnosti, proizvodnja, uporaba in shranjevanje metanola kot alternativnega goriva in nosilca energije. V eksperimentalnem delu smo zasnovali procesno shemo, ki vključuje kompresijo reaktantov, sintezo produktov v reaktorju, fazno ločevanje ter čiščenje končnega produkta. Rezultati računalniške simulacije kažejo vpliv temperature in tlaka na konverzijo CO2 in selektivnost do metanola. Občutljivostna analiza je potrdila, da je vrednost refluksnega razmerja in tlaka ključnega pomena za izboljšanje izkoristka in čistosti končnega produkta. Ugotovili smo, da je računalniška simulacija uporabno orodje za predhodno vrednotenje rezultatov trajnostnih kemijskih procesov ter da je proizvodnja metanola iz obnovljivih virov energetsko in okoljsko smiselna alternativa klasični proizvodnji. Proizvodnja metanola iz obnovljivih virov energije predstavlja pomemben korak k zmanjšanju emisij toplogrednih plinov in razogljičenju industrije. Takšni procesi omogočajo učinkovito izrabo presežkov električne energije iz obnovljivih virov in prispevajo k razvoju krožnega gospodarstva ter energetski neodvisnosti.

Title:Synthetic methanol production from CO2 and sustainable hydrogen
Abstract:This thesis discusses the possibility of sustainable production of synthetic methanol from carbon dioxide and hydrogen obtained by electrolysis of water using renewable energy sources. The aim of this thesis was to develop a computer model of the methanol synthesis process using the Aspen Plus software package and to analyze the effects of the main operating parameters on the efficiency of the process. In the theoretical part, sources and methods of hydrogen production, the possibility of CO2 capture and the properties, production, use and storage of methanol as an alternative fuel and energy carrier are presented. In the experimental part, we have designed a process scheme that includes the compression of the reactants, the synthesis of the products in the reactor, the phase separation and the purification of the final product. The results of the computer simulation show the influence of temperature and pressure on the CO2 conversion and the selectivity to methanol. The sensitivity analysis confirmed that the value of reflux ratio and pressure is crucial to improve the yield and purity of the final product. We found that computer simulation is a useful tool for preliminary evaluation of the results of sustainable chemical processes and that methanol production from renewable sources is an energetically and environmentally viable alternative to conventional production. The production of methanol from renewable energy sources is an important step towards reducing greenhouse gas emissions and decarbonizing the industry. Such processes enable the efficient use of surplus electricity from renewable sources and contribute to the development of a circular economy and energy independence.
