abstract = "In addition to lime / limestone process, the most common procedure for sulfur-dioxide (SO2) removal from flue gases, separation processes with physical absorption and liquid organic solvent thermal regeneration recently gained importance. Organic liquid solvent selection, ahead of other process parameters, is crucial for process separation efficiency, in terms of the amount of SO2 absorbed by the solvent. The paper presents literature review and analysis of SO2 solubility in currently used and potential liquid organic solvents, polyethylene glycols (PEG 200 and PEG 400), tetraethylene glycol dimethyl ether (TEGDME), 1-methyl-2-pyrrolidone (NMP) as well as their binary mixtures with other components. The solvents in question bind SO2 by physical absorption mechanism, with the exception of NMP which binds SO2 by two parallel mechanisms, physical and chemical absorption. Research have even shown that mixtures of physical and chemical solvents or presence of both absorption mechanisms sometimes show better characteristics regarding binding capacity and selectivity. The importance of ionic liquids, as future solvents for separation processes, is particularly highlighted, due to their favorable thermophysical properties., Pored najrasprostranjenijeg, krečnjačkog postupka, za uklanjnje sumpor-dioksida (SO2) iz dimnih gasova, u novije vreme sve veći značaj dobijaju separacioni postupci sa fizičkom apsorpcijom i termičkom regeneracijom tečnog organskog solventa. Izbor solventa, ispred drugih procesnih parametara, ključan je za efikasnost procesa u pogledu stepena izdvajanja SO2. U radu je dat literaturni pregled i analiza rastvoljivosti SO2 u trenutno korišćenim i potencijalnim tečnim organskim solventima, polietilen glikolima (PEG 200 i PEG 400), tetraetilen glikol dimetil etru (TEGDME), 1-metil-2-pirolidonu (NMP) i za njihove binarne smeše sa drugim komponentama. Razmatrani solventi vezuju SO2 mehanizmom fizičke apsorpcije, sa izuzetkom NMP-a kod koga su prisutna dva paralelna mehanizma, fizička i hemijska apsorpcija. Istraživanja su čak pokazala da smeše fizičkih i hemijskih solvenata ili smeše u kojima su prisutni mehanizmi i fizičke i hemijska apsorpcije ponekad pokazuju bolje karaktristike u pogledu stepena izdvajanja i selektivnosti. Posebno je istaknut značaj jonskih tečnosti kao solvenata budućnosti za separacione proces, zbog svojih povoljnih termofizičkih svojstava.",
