20.500.12556/DKUM-95148 Modeliranje procesa proizvodnje ocetne kisline iz trdnih komunalnih odpadkov magistrsko delo Production of acetic acid from solid municipal waste V magistrskem delu je predstavljena analiza proizvodnje ocetne kisline iz trdnih komunalnih odpadkov (TKO) z uporabo programske opreme Aspen Plus. Namen dela je bil ovrednotiti vpliv sestave odpadkov in procesnih parametrov na donos končnega produkta, ki ga predstavlja ocetna kislina. Osredotočili smo se na štiri različne scenarije: sortirane TKO, sortirane TKO z dodatkom CO2, delno sortirane TKO z dodatkom CO2 in nesortirane TKO z dodatkom CO2. V eksperimentalnem delu smo zasnovali procesne simulacije, ki vključujejo vse ključne enote za proces od uplinjanja do sinteze ocetne kisline. Spremljali smo molske pretoke (F) vmesnih produktov in glavnega produkta, temperaturne in tlačne profile skozi proces ter toplotne tokove (Q) in mehansko moč kompresorjev (P). Rezultati kažejo, da je sestava vhodnih TKO ključnega pomena za stabilnost procesa in izkoristke. Sortirani TKO omogočajo najboljšo in najbolj stabilno proizvodnjo, pri čemer dodatek CO2 še dodatno poveča donos sinteznega plina (SP) in posledično metanola ter ocetne kisline. Pri nesortiranih TKO se pojavljajo večja nihanja zaradi vlage in inertnih komponent, kar zmanjšuje učinkovitost procesa. Ugotovili smo, da je optimalna rešitev proizvodnja ocetne kisline iz sortiranih TKO z dodatkom CO2, saj zagotavlja največji donos, stabilne procesne pogoje ter bolj uravnoteženo porazdelitev toplotnih tokov. Delo prispeva k boljšemu razumevanju možnosti energetske in kemijske valorizacije TKO ter ponuja smernice za optimizacijo procesov, ki lahko pomembno vplivajo na trajnostno ravnanje z odpadki. The master’s thesis presents modeling the acetic acid production process from municipal solid waste using Aspen Plus software. The aim of the work was to evaluate the impact of waste composition and process parameters on the yield of the final product, acetic acid. We focused on four different scenarios: sorted municipal solid waste, sorted municipal solid waste with CO2 addition, partially sorted municipal solid waste with CO2 addition and unsorted municipal solid waste with CO2 addition. In the experimental part, we designed process simulations that included all key units of the process from gasification to acetic acid synthesis. We monitored the molar flows of intermediate and final product, temperature and pressure profiles throughout the process, as well as heat flow (Q) and compressor mechanical power (P). The results show that the composition of the input municipal solid waste plays a crucial role in process stability and yields. Sorted municipal solid waste enables the best and most stable production, while the addition of CO2 further increases the yield of syngas and, consequently, methanol and acetic acid. In the case of unsorted municipal solid waste, larger fluctuations occur due to moisture and inert components, which reduce process efficiency. We found that the optimal solution is acetic acid production from sorted municipal solid waste with CO2 addition, as it ensures the highest yield, stable process conditions, and a more balanced distribution of the heat flows. Work contributes to a better understanding of the potential for energy and chemical valorization of municipal solid waste and provides guidelines for process optimization, which can significantly support sustainable waste management. ocetna kislina Aspen Plus sintezni plin trdni komunalni odpadki metanol modeliranje kemijskih procesov acetic acid Aspen Plus syngas municipal solid waste methanol chemical process modeling true true false [I.
