Abstract:	Formalin je pomembna kemikalija, ki se proizvaja v velikih količinah, njegova proizvodnja pa je energetsko zahteven proces. Zmanjšanje porabe energije procesa bi prispevalo tako k ekonomskim prihrankom kot tudi k zmanjšanim okoljskim vplivom in bi omogočilo bolj trajnostno proizvodnjo formalina kot vmesnega ali končnega produkta. Cilj magistrskega dela je izboljšanje trajnosti proizvodnega procesa formalina preko reformiranja metana z analizo energetskega, ekonomskega in okoljskega vidika. Na simuliran proces je bila uvedena toplotna integracija, ki je bila izvedena s pomočjo uščipne metode in matematičnega programiranja, kjer smo uporabili pretovorjevalni optimizacijski model. Za izvedbo toplotne integracije smo uporabili sekvenčni pristopom, pri čemer smo najprej minimirali stroške pogonskih sredstev, nato smo minimirali število toplotnih prenosnikov ter nazadnje sintetizirali omrežje toplotnih prenosnikov. Za procesa pred in po toplotni integraciji smo izvedli ekonomsko analizo na osnovi investicijskih in obratovalnih stroškov, kjer smo uporabili faktorsko metodo. Izvedena je bila tudi analiza življenjskega cikla, s katero smo ocenili okoljske vplive procesa pred in po toplotni integraciji. Rezultati kažejo, da toplotna integracija procesa zmanjša porabo pogonskih sredstev za 39 %, kar posledično vodi do 11 % prihrankov v investicijskih stroških. Toplotna integracija izboljša proces tudi z okoljskega vidika, kjer so okoljski vplivi zmanjšani za 7 do 22 % v izbranih kategorijah vpliva. Študija v magistrskem delu služi kot izhodišče za nadaljnje raziskave izboljšanja trajnosti proizvodnje formalina.

Title:	Analysis of production processes for sustainable production of formalin
Abstract:	Production of formalin, which is a high production volume chemical, is a highly energy-intensive process. Reduction of process energy consumption would contribute to both economic savings and to mitigation of environmental impacts and allow for more sustainable production of formalin as an intermediate or final product. The aim of this thesis is to improve sustainability of the formalin production process via methane steam reforming by analyzing its energy, economic and environmental aspects. Heat integration was applied to the simulated formalin production process, which was performed using pinch analysis and mathematical programming, including a transshipment optimization model. Heat integration was carried out using a sequential approach, first minimizing total utility costs, further minimizing the number of heat exchangers, and finally synthesizing the heat exchanger network. For the process before and after heat integration, economic analysis was performed based on investment costs and operating costs, where the factor method was used. A life cycle assessment was additionally performed to assess the environmental impacts of the process before and after heat integration. Results show that heat integration of the process reduces utility consumption by 39 %, which in turn leads to 11 % savings in investment costs. Heat integration also improves the environmental aspect of the process, where selected impact categories are reduced by 7 to 22%. The study in this master's thesis serves as a starting point for further research to improve sustainability of formalin production.
Keywords:	Formalin production process, heat integration, energy consumption reduction, economic performance, environmental analysis.
