Abstract

U ovom radu provodi se istraživanje i simulacija procesa adsorpcije promjenom tlaka (eng. Pressure Swing Adsorption, PSA) za uklanjanje ugljikova (IV) oksida iz dimnih plinova energetskih postrojenja. PSA je separacijska tehnologija koja se temelji na različitim afinitetima pojedinih komponenata u plinskoj fazi prema čvrstom adsorbensu, uz korištenje cikličke promjene tlaka kako bi se omogućila regeneracija adsorbensa. Atraktivnost ove tehnologije nalazi se u njenom jednostavnom postavljanju i provedbi uz prihvatljivu energetsku učinkovitost te mogućnost selektivnog odvajanja CO2. U radu je provedena simulacija PSA procesa koristeći dvije kolone koje rade paralelno s vremenskom razlikom u koracima procesa kako bi se postigla kontinuiranost uklanjanja CO2. Cilj istraživanja bio je postizanje čistoće CO2 na izlazu procesa veće od 99,0 mol %, uz što veći iscrpak CO2 iz dimnih plinova koristeći NOTT-300 adsorbens. Rezultati simulacije pokazuju mogućnost optimizacije PSA procesa u smislu osiguranja čistoće i učinkovitosti uklanjanja CO2, što ovaj proces čini pogodnim za primjenu u industriji s ciljem smanjenja emisija stakleničkih plinova.

Abstract (english)

This paper presents research and simulation of the Pressure Swing Adsorption (PSA) process for the removal of carbon dioxide (CO2) from the flue gases of energy generation plants. PSA is a separation technology based on the different affinities of individual components in the gas phase towards a solid adsorbent, utilizing cyclic pressure changes to enable the regeneration of the adsorbent. The attractiveness of this technology lies in its relatively simple setup and implementation, combined with acceptable energy efficiency and the ability to selectively separate CO2. In the study, a simulation of the PSA process was conducted using two columns operating in parallel with a time offset in process steps to achieve continuous CO2 removal. The goal of the research was to achieve a CO2 purity of over 99,0 mol % at the process outlet while maximizing the CO2 recovery from the flue gases. The simulation results demonstrate the potential for optimizing the PSA process in terms achieving the required purity and recovery of CO2 removal process, making it suitable for industrial applications aimed at reducing greenhouse gas emissions.
