Abstract

U sklopu diplomskog rada bilo je potrebno projektirati rektifikacijsku kolonu za vakuumsku
destilaciju smjese etanol-voda, radi povećanja kapaciteta postojećeg postrojenja za atmosfersku
destilaciju. Provedena je optimizacija potrošnje topline tako što su se postojeće procesne struje
postrojenja za atmosfersku destilaciju povezale mrežom izmjenjivača topline s procesnim
strujama postrojenja za vakuumsku destilaciju kako bi se postigla maksimalna ušteda energije.
Nakon provedene optimizacije potrošnje energije, određen je teorijski broj stupnjeva. Pošto se
radi o vakuumskoj destilaciji odabrana su strukturirana punila. Proveden je termodinamički
proračun svih termodinamičkih uređaja u postrojenju za vakuumsku destilaciju. Kao vanjski
toplinski spremnici koriste se suho zasićena vodena para tlaka 6 bar i rashladna voda
temperature 15°C.

Abstract (english)

As part of the graduate thesis, it was necessary to design a rectification column for the vacuum
distillation of the ethanol-water mixture to increase the capacity of the existing atmospheric
distillation plant. Optimization of heat consumption has been made by having the process
streams of the atmospheric distillation plants connected by the heat exchanger network with the
process streams of the vacuum distillation plant to achieve the maximum energy savings. After
the optimization of the energy consumption, the theoretical number of the trays was determined.
Because this is vacuum distillation, structured packings are selected. A thermodynamic
calculation of all thermodynamic devices in the vacuum distillation plant was performed. As
outdoor heat tanks a dry saturated steam at 6 bar and cooling water temperature of 15°C are
available.
