The concern of climate change and global warming has consecutively risen to progress research fields pledging to find the possible solutions. The use of fossil fuels for energy leads to an increase in CO 2 emission causing environmental problems like global warming and climate change. For industrial applications, aqueous solutions of amines are extensively used as chemical absorbent or solvent. However, amine reaction with CO 2 results in stable carbamate formation, which in turn leads to high energy usage for regeneration and promote additional corrosion problems. To overcome these restrictions, this study proposes a methodology to analyze the performance of new solvent namely amino acid salt solution. Evaluation of solvent performance in terms of CO 2 loading and designing of acid gas removal system, requires pressure solubility data and design properties like density, pH value and refractive index. © Published under licence by IOP Publishing Ltd.
