20.500.12556/DKUM-68404 Proizvodnja transportnega goriva iz bioplina Production of transport fuel from biogas V diplomskem delu je prikazan postopek proizvodnje metana (CH4) iz bioplina pridobljenega z anaerobno digestijo bioloških odpadkov. Tako proizveden metan se lahko uporablja za proizvodnjo električne energije s plinskimi motorji, se dodaja v plinovod za oskrbo gospodinjstev ali kot gorivo za transportna sredstva z motorjem z notranjim izgorevanjem. Iz bioplina je potrebno najprej odstraniti ogljikov dioksid in druge nečistoče, ki nastanejo pri anaerobni digestiji. Računalniške simulacije čiščenja bioplina smo izvedli s programskim paketom Aspen Hysys. Odstranjevanje posameznih nezaželenih komponent bioplina pri postopku čiščenja smo izvajali postopoma, najprej z odstranjevanjem vodikovega sulfida (H2S) in ogljikovega dioksida (CO2) z absorpcijo z dietanolaminom (DEA). Nato smo z drugim procesom odstranjevali vodo (H2O) z absorpcijo s TEGlikolom. Tretji proces predstavlja kriogensko destilacijo dušika (N2). Četrti oziroma zadnji proces pa predstavlja računalniško simulacijo separacije metana (CH4) od prestale plinske zmesi in komprimiranje na željeni tlak. The bachelor thesis presents the process of production of methane (CH4) from biogas produced by anaerobic digestion of bio-waste. In such a way produced Methane can be used to produce electricity with gas engines, is added to a gas supply for households or as fuel for transport vehicles with internal combustion engines. Carbon dioxide and other impurities created during anaerobic digestion must first be removed from biogas. The computer simulations of biogas cleaning were performed with the Aspen Hysys software package. The removal of individual unwanted biogas components in the purification process was carried out gradually, first by removing hydrogen sulphide (H2S) and carbon dioxide (CO2) by absorption with diethanolamine (DEA). With the second process, water (H2O) was removed by absorption with TEGlikol. The third process represents the cryogenic distillation of nitrogen (N2). The fourth and final process is a computer simulation of methane separation (CH4) from the gas gas mixture and compression to the desired pressure. bioplin proizvodnja metana separacija plinov transportno gorivo računalniška simulacija biogas methane production gas separation transport fuel computer simulation true true false [M.
