Performance of aqueous tetrabutylammonium hydroxide, piperazine and their blends for carbon dioxide capture

The potential of aqueous ammonium based IL, tetrabutylammonium-hydroxide (TBAOH), the aqueous tertiary amine, piperazine (PZ) and two aqueous solutions of TBAOH and PZ blend for CO2 capturing was estimated by solubility study. For this purpose, the experiments were carried at five different pressure...
