Abstract: A solvent for recovery of carbon dioxide from gaseous mixture having at least amine, and at least one salt of an amino carboxylic acid or amino sulfonic acids. One specific solvent contains less than about 75% by weight of water and has a single liquid phase.
Abstract: The present disclosure provides for a solvent composition for recovery of carbon dioxide from gaseous mixture, comprising diethanolamine, piperazine or its derivative, alkali salt, optionally along with cupric carbonate. The disclosure relates to improved solvent formulations that utilizes less energy and increased carbon capture efficiency. The disclosure also addresses the high CO2 loading capacity and energy requirement over the existing carbon dioxide capture solvent.
