20.500.12556/DKUM-13555 POVEČANJE PRESNOVE METANA V PROCESU PROIZVODNJE METANOLA INCREASED CONVERSION OF METHANE IN THE METHANOL PROCESS V industrijskih obratih, v katerih poteka proizvodnja metanola, se proizvodnja lahko vrši pri visokem, srednjem ali nizkem tlaku. V okviru diplomskega dela smo opravili del raziskovalne študije za Nafto Petrochem, d. o. o., v kateri je bila naša glavna naloga povečanje presnove metana v procesu proizvodnje metanola. Proizvodnjo metanola smo simulirali z računalniškim procesnim simulatorjem Aspen Plus z modelom, ki vključuje kemijsko termodinamiko za realne procese. Povečanje presnove metana poteka v parnem reformerju pri nizkem tlaku. S povečanjem presnove metana proizvedemo večjo količino sinteznega plina in s tem večjo količino metanola. Na povečanje presnove metana smo vplivali s spremembo temperature in tlaka, ki sta najpomembnejša procesna parametra v našem procesu. S podrobno analizo vseh zbranih podatkov, smo preučili in ugotovili, kateri od spremenjenih procesnih parametrov najbolj ugodno vplivajo na povečanje presnove metana pri proizvodnji metanola. In industrial plants where methanol is produced, the production can be taken at high, medium or low pressure. With this diploma taks, we have done a part of research studies for Nafta Petrochem, d. o. o., where our main task was to increased the prediction conversion of methane in the methanol production process. The research study was conducted with procedural computer simulator Aspen Plus with model, which includes chemical thermodynamics for real processes. Increasing the prediction conversion of methane is taking place in the steam reformer at low pressure. When we increased the prediction conversion of methane, we can produce a larger amount of synthesis gas and consequently a large amount of methanol. Increasing the prediction conversion of methane was influenced by changing temperature and pressure, which are the most important process parameters in our process. With detailed analysis of all collected data, we have examined and found, which of the modified process parameters have the most favorable effect on the increased prediction conversion of methane in the production of methanol.
