Abstract

As climate change worsens worldwide, there is a drive to develop more efficient and sustainable methods to mitigate its impact through carbon capture methods like carbon dioxide scrubbing. Carbon scrubbing directly captures carbon dioxide (CO2) emissions from industries or power plants before they are released into the environment. The CO2 captured can be utilized for various applications or can be stored underground. However, this method faces numerous challenges, such as the degradation of the solvent or corrosion of equipment. As a result, research has expanded to find a better medium to overcome these issues. In particular, aqueous ionic amines (AIA) are novel salts that are nonvolatile and highly thermally stable. Not much is known about the compounds studied in this research, so preliminary data measurements such as density, solubility, viscosity, and surface tensions are needed to model these compounds in an industrial setting. The focus of this research is the collection of density measurements for these compounds with and without CO2. The density measurements were collected over a temperature range of 20 to 80 °C at mass percentages ranging from 15-55%. The property measurements altogether will aid in future design and optimization purposes for industries. Additionally, understanding these properties will lay the groundwork for developing better and more efficient solvents to be used for carbon capture.
