20.500.12556/DKUM-54648 Posodobitev dimnega kanala MODIFICATION OF FLUE CHANNEL Opravili smo raziskavo o posodobitvi dimnega kanala v procesu proizvodnje metanola za podjetje Nafta Petrochem d.o.o.. Najprej smo simulirali s procesnim simulatorjem Aspen Plus dejansko menjavo toplotnega toka v dimnem kanalu in proizvodnjo 37 barske pare, nato pa še posodobitev dimnega kanala in proizvodnjo 37 barske pare. Za posodobitev dimnega kanala smo del toplotnega toka iz zračnega hladilnika uporabili za segrevanje zraka, ki je potreben za sežig in ta razpoložlivi toplotni tok v dimnem kanalu smo uporabili za razširitev proizvodnje 37 barske pare za 4%. Ugotovili smo, da posodobitev ne bi zahtevala razširitve procesa, saj proces deluje z 80% kapaciteto. Potrebno bi bilo le uporabiti razpoložlivi toplotni prenosnik, ki ga imajo v podjetju in povezati z novim ocevjem. We conducted a survey on the modernization of the flue gas channel in the methanol production process for the company Nafta Petrochem d.o.o. First, we simulated with the process simulator Aspen Plus an actual changing heat flow in the flue channel and the production of 37 bar steam and then updated the flue channel and the production of 37 bar steam. To update the flue channel, a portion of the heat flux from the air cooler is used to heat the air that is needed for combustion and the available heat flux in the flue channel was used to expand the production of 37 bar steam for 4%. We found out that the update would not require the extension of the process, because the process operates at 80% capacity. There should be only used disposable heat exchanger, which they have in the company and connect with new tubes. dimni kanal segrevanje zraka za sežig proizvodnja 37 barske pare flue channel heating of air for combustion production of 37 bar steam true true false [S.
