摘要

The aim of this work is to find the effect of the adding graphene oxide nanoparticle ands dodecyl sulfate (SDS) on the absorption rate and solubility of CO~(2)in mono-ethanolamine (MEA) solvent. To this end, an experimental setup was designed and constructed to measure the gas solubility in the solvent and the absorption rate during the process. The experiments were conducted at ambient temperature and initial pressure of 20?bar. The parameters analyzed in this paper included GO-NPS at 0.0375, 0.05, 0.075 and 0.1%, SDS at the same percentages, and the simultaneous effects of both additives. In each experiment, the absorption rate and solubility were calculated by recording the temperature and pressure variations in the absorption and loading chambers. The results indicated that the highest effect of GO-NPS was in the concentration of 0.05%, increasing solubility by up to 7.62%. These values for SDS were 0.075% and 8.39%, respectively. In the experiment with both additives at 0.05% and 0.075% for GO-NPS and SDS, solubility increased by 6.32% and simultaneous presence of both compounds had the greatest effect on absorption rate. Comparison of the results of mole variations suggested that addition of nanoparticles and surfactants both increased the absorption rate.
