Surprisingly, sulfolane was determined to be a universal phase splitting solvent in a serial aqueous primary alkanolamine solution for CO2 removal, where carbamate and hydrophilic amine reaction product can be the key factor to trigger CO2 phase change; the phase change can also significantly affect CO2 absorption performance. To comprehensively understand the phase change effect on absorption, stripping, and phase separation performance of primary alkanolamine solution for CO2 capture, a monoethanolamine/sulfolane-based solution was chosen as typical biphasic system. Exptl. results showed phase change can dramatically decrease absorption rate and lead to less CO2 capacity in an absorption process. The MEA-enriched separated solution can substantially decrease energy consumption for CO2 stripping, but exorbitant MEA concentration can significantly reduce CO2 removal efficiency in a quasi absorption/desorption cycle. The MEA/sulfolane emulsion solution phase separation rate can be improved by increasing temperature; fortunately, increasing temperature had a smaller effect on the miscible solubility of MEA and sulfolane in the two separated phases. Considering the absorption rate, energy consumption, and phase separation rate, a new technol. process was proposed for CO2 capture using a primary alkanolamine/sulfolane-based solution to achieve relatively high CO2 removal efficiency and conserve energy. The experimental process involved the reaction of 3-Aminopropan-1-ol(cas: 156-87-6Name: 3-Aminopropan-1-ol)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Milder oxidation, using reagents such as NaOCl, can remove four hydrogen atoms from primary amines of the type RCH2NH2 to form nitriles (R―C≡N), and oxidation with reagents such as MnO2 can remove two hydrogen atoms from secondary amines (R2CH―NHR′) to form imines (R2C=NR′). Tertiary amines can be oxidized to enamines (R2C=CHNR2) by a variety of reagents.Name: 3-Aminopropan-1-ol
