Energetsko i ekonomsko poboljŔanje procesa sinteze metanola primenom Pinch tehnologije
A heat exchanger network (HEN) for the process of methanol synthesis has been studied by pinch design analysis. Great economic and energy savings were realized by the pinch analysis in comparison to the existing plant. Also, it was found that it is possible to reduce the requirements for the consumption of utilities. The HEN was reconstruded by adding new heat exchangers. In order to produce new HEN, the capital costs had to be increased, but the total cost trade-off between the capital and energy costs will be decrease by 30 %.U ovom radu je pokazano kako se primenom Pinch metodologije na rekonstrukciju postojeÄe mreže razmenjivaÄa toplote, u posmatranom industrijskom postrojenju mogu dobiti znatne energetske i ekonomske uÅ”tede. ProuÄavan je proces sinteze metanola i prikazana je moguÄnost smanjenja troÅ”kova vezanih za energetske zahteve u procesu pre svega vezanih za koriÅ”Äewe pomoÄnih toplotnih izvora. Dobijeni rezultat ukazuje da je za rekonstrukciju neophodno uvoÄenje novih razmenjivaÄa toplote, Å”to poveÄava kapitalne troÅ”kove same mreže ali ukupni troÅ”kovi, koji obuhvataju kapitalne i energetske troÅ”kove, su smanjeni za oko 30 %
