Viscosity Measurement and Physical Correlation of Aqueous Blends of Potassium Carbonate and Ammonium-Based Ionic Liquid

Release of carbon dioxide into atmosphere by sources such as chemical industries, open burning and motorised vehicles poses various detriments towards people, animals and environment alike. The effort of absorbing carbon dioxide has been implemented and ways to improve the performance is continuously discovered. The know-how of physical and thermal property such as viscosity solvent systems are prerequisite in analysing and evaluating mass transfer and CO2 capture capacity for the rational design and optimization of acid gas treatment processes. Viscosity data of these aqueous solutions are also vital for the separation of acid gases using microporous membranes as a gas-liquid contactor. However, the data for the blends of potassium carbonate (K2CO3) + tetrabutylammonium hydroxide (TBAOH) is still unavailable, which creates a knowledge gap to use these types of IL and their blends for various purposes. The study will be done by measuring the viscosity of blends in temperatures 303.15 K to 333.15 K (30oC – 60oC) and varying concentrations. The viscosity will be calculated using Hoppler’s principle and least-square method to calculate deviation between values.
