Abstract:V zadnjem času se pospešeno raziskujejo možnosti pridobivanja energije, goriv in raznih kemikalij iz bioplina. Bioplin, ki je sestavljen predvsem iz CH4 in CO2, lahko uporabimo za proizvodnjo sinteznega plina, iz katerega pa lahko pridobivamo etanol. Etanol se lahko uporablja kot alternativno gorivo za motorna vozila in za ogrevanje stanovanj. V hrani in pijači deluje kot konzervans ali sredstvo za aromatiziranje. Prav tako pa se pogosto uporablja kot surovina v kemijski in farmacevtski industriji. V okviru magistrske naloge smo obravnavali proizvodnjo etanola iz bioplina. Osnovni cilj magistrske naloge je bil določiti optimalne pogoje za proizvodnjo etanola iz bioplina s pomočjo programa Aspen Plus. V ta namen smo izvedli numerično simulacijo proizvodnje etanola pri različnih obratovalnih pogojih (temperatura, tlak) in pri različnih sestavah vhodne surovine (količina dodanega CO2 in vodne pare). Z analizo teh vplivnih parametrov smo določili optimalne pogoje za proizvodnjo etanola. Dobljeni rezultati kažejo, da največjo količino nastalega etanola dosežemo pri temperaturi 200 °C, tlaku 50 bar, količini dodanega CO2 300 kmol/h in pri količini dodane vodne pare 400 kmol/h. Pri teh optimalnih vrednostih vplivnih faktorjev se lahko količina proizvedenega etanola poveča tudi do 15 %.

Title:Production of ethanol from biogas
Abstract:Lately, the possibilities of obtaining energy, fuels and various chemicals from biogas are being researched. Biogas, which consists mainly of CH4 and CO2, can be used to produce synthesis gas, from which ethanol can be produced. Ethanol can be used as an alternative fuel for motor vehicles and for heating homes. In food industry, it acts as a preservative or flavouring agent. It is also widely used as a raw material in the chemical and pharmaceutical industries. As part of the master’s thesis, we dealt with the production of ethanol from biogas. The main objective of the master’s thesis was to determine optimal conditions for the production of ethanol from biogas with the help of the Aspen Plus programme. For this purpose, we carried out a numerical simulation of ethanol production under different operating conditions (temperature, pressure) and with different feedstock compositions (amount of added CO2 and water vapour). By analyzing these influential parameters, we determined the optimal conditions for ethanol production. The results show that the maximum amount of ethanol produced is reached at a temperature of 200 °C, at a pressure of 50 bar, at a rate of added CO2 of 300 kmol/h and at a rate of added water vapour of 400 kmol/h. At these optimal influencing factor values, the amount of ethanol produced can be increased by up to 15%.
