Abstract

Kolona s razdjelnom stijenkom (KRS) potpuno je toplinski povezana destilacijska kolona u kojoj je moguće provesti razdvajanje kapljevitih smjesa s tri ili više komponenata u proizvode visoke čistoće. U usporedbi s konvencionalnim nizovima kolona, KRS zahtijeva značajno manje energije i prostora, smanjujući investicijske i pogonske troškove. Glavni uzrok sporog prihvaćanja ove tehnologije je nedostatak jednostavne i provjerene metode dimenzioniranja, te složenost odabira i provjere sustava za vođenje. Koristeći procesne simulatore CHEMCAD i HYSYS razvijeni su statički i dinamički modeli KRS-a za separaciju višekomponentne smjese na četiri proizvoda. Sustav vođenja ispitan je provođenjem dinamičkih simulacija, pri čemu su se pratili sadržaji ključnih komponenata u proizvodima.

Abstract (english)

Dividing wall column (DWC) is a fully thermally coupled distillation column capable of separating mixtures of three or more components in high purity products. Compared to conventional columns in series, the dividing wall column requires significantly less energy and space, reducing investment and operating costs. The main cause of the slow implementation of this technology is lack of simple and proven dimensioning methods, and the complexity of selecting and testing the control structure. Using process simulators CHEMCAD and HYSYS, static and dynamic models were developed to separate multicomponent blends into four products. The control structure was tested using dynamic simulations, whereby the contents of key components in the products were monitored.
