Transport and Optical Properties of n-Butylamine plus Alkanols (C3-C4) Mixtures for Enhanced CO2 Absorption

초록

Reducing carbon emissions has emerged as a critical challenge, and among various methods, solvent-based CO2 capture technology is the most widely employed. Amines, particularly effective solvents for CO2 capture, play a significant role in this process. To advance this technology, it is essential to understand the thermodynamic properties of the interactions between the constituent components. In this study, we examined the deviation in dynamic viscosity (Delta eta), and the deviation in refractive index (Delta n(D) ) calculated from the measured eta and n(D) data for n-butylamine (NBA) with alkanol systems. The temperature range for our study was 298.15-318.15 K. We utilized the Ab-initio approach for Delta eta data analysis. Our findings revealed that the depolymerization power of alkanol is dependent on the unlike interactions. Furthermore, we employed various correlations/mixing rules to predict the lambda as well as n(D) values from the experimental pure components data. The standard deviation was utilized to express the predictive abilities of these correlations.
