Abstract
Fluidizirano katalitičko krekiranje (engl. fluidized catalytic cracking, FCC), kao jedan od najvažnijih sekundarnih procesa u rafinerijama, predstavlja pretvorbu teških naftnih frakcija u lakše frakcije pri visokim temperaturama i umjerenom tlaku uz prisutnost sintetičkih zeolita kao katalizatora. Sastoji se od pet tehnoloških sekcija, od kojih je najznačajnija katalitička sekcija u kojoj krekiranjem zasićenih ugljikovodika, uz frakcije glavnog proizvoda benzina, nastaju frakcije ukapljenog naftnog plina (UNP-a). U sekciji koncentracije plina iz UNP-a dobiva se propan/propen (propilen) frakcija koja se u propan-propilen postrojenju (engl. propane/propylene splitter, PPS) razdvaja na komponente. Propilen je izuzetno bitan proizvod jer predstavlja vrlo važnu petrokemikaliju. U ovom radu pratile su se izmjene u radu FCC kompleksa i PPS postrojenja Rafinerije nafte Rijeka, INA d.d. u lipnju 2024. godine te njihov utjecaj na konačni iscrpak propilena. U FCC kompleks su dozirani ZSM-5 aditiv i HCU benzin (iz postrojenja hidrokrekiranja), dok se recirkulacija propilena vršila u PPS postrojenju. Utvrđeno je da je doziranje ZSM-5 aditiva i HCU benzina utjecalo na povećanje ukupne količine plinova u FCC kompleksu, odnosno na povećanje konačnog iscrpka propilena traženih specifikacija u PPS postrojenju, dok je recirkulacija propilena smanjila iscrpak proizvedenog propilena.
Abstract (english)
Fluidized catalytic cracking (FCC), as one of the most important secondary processes in refineries, represents the conversion of heavy petroleum fractions into lighter fractions at high temperatures and moderate pressure in the presence of synthetic zeolites as catalysts. It consists of five technological sections, the most significant being the catalytic section, where the cracking of saturated hydrocarbons produces, in addition to gasoline as the main product, fractions of liquefied petroleum gas (LPG). In the gas concentration section, a propane/propylene fraction is obtained from the LPG, which is then separated into components in the propane/propylene splitter (PPS) unit. Propylene is an extremely important product as it represents a very significant petrochemical. This paper monitored the changes in the operation of the FCC complex and the PPS unit at the Rijeka Oil Refinery, INA d.d., in June 2024, and their impact on the final propylene yield. The ZSM-5 additive and HCU gasoline (from the hydrocracking unit) were dosed into the FCC complex, while propylene recirculation was conducted in the PPS unit. It was determined that the dosing of ZSM-5 additive and HCU gasoline led to an increase in the total amount of gases in the FCC complex and consequently increased the final propylene yield of the required specifications in the PPS unit, while propylene recirculation reduced the yield of produced propylene.
