Abstract
Conventional industrial processes for CO2 capturing include gas absorption by solvent. The most common solvent consisting of an aqueous solution of methyl di-ethanol amine (MDEA) activated with Piperazine (PZ). This research however examines CO2 solubility in absorption and desorption process using the above mentioned solvent that reinforced by nanoparticles additives at concentrations of 12, 25, 50, and 100 ppm, respectively. In this novel solvent Carbon dioxide solubility was studied at 40 and 120°C. These tests conducted at 0.1 to 26 atm partial pressure of CO2 and Vapor–Liquid Equilibrium (VLE) data were obtained from laboratory setup. The results indicate an increase in CO2 loading and changing on solubility equilibrium curve to more concentration of CO2 in liquid phase for solvent containing nanoparticles. The solvent CO2 loading was enhanced up to 37.5% by introducing 25 ppm of our novel nanoparticles.
