This study examines the formation of thermally stable salts (TSS) formed during the absorption of acid gases (H2S and CO2) in amine absorber systems based on diethanolamine (DEA), their impact on process efficiency, and methods for reducing them. During the study, purified and saturated DEA solutions were analyzed by titration. Based on the experimental results, it was established that increasing the TS content reduces the regeneration capacity of DEA, causes foaming in the absorber, and slows the process. The efficiency of separating the TS from the solution using an ion-exchange resin (Dowex 50W-X8) was also evaluated. The results showed that treatment with a cation exchanger improves DEA regeneration and reduces amine consumption
