The continuous emission of carbon dioxide from fossil fuel combustion, a major driver of global warming and extreme weather events, poses a critical threat to human survival. As data centers powered by artificial intelligence emerge as new growth engines worldwide, they also intensify electricity demand, potentially increasing the use of fossil fuels such as LNG. Carbon capture, utilization, and storage (CCUS) techno logies offer a direct means of managing CO₂ emissions from such sources. Among them, chemical absorption using aqueous amines is considered a relatively mature technology, especially suitable for large-scale flue gas with low CO₂ concentrations.

To ensure cost-effective operation of CO₂ capture processes, newly developed absorbents should exhibit low regeneration energy, strong resistance to degradation caused by oxygen and metal ions (e.g., Fe²⁺/Fe³⁺), and economic feasibility. Once a high-performance absorbent is developed, accurate physicochemical characterization-including a comprehensive Material Safety Data Sheet (MSDS)-is essential for commercialization. In addition, precise measurements of process design parameters under operating temperatures and pressures are crucial. Real-time monitoring of CO₂ loading and degradation products during process operation is also necessary.

In this study, we present the measured physicochemical properties of a high-efficiency blended amine CO₂ absorbent, including density, viscosity, surface tension, vapor pressure, specific heat, vapor-liquid equilibrium, reaction rate constants, water-octanol partition coefficient, flash point and so on. The experimentally obtained data under actual operating conditions were used to derive empirical correlations, which were then incorporated into the finalized MSDS. This presentation will discuss the overall process from experimental characterization to the derivation of process design parameters and considerations for commercialization of the newly developed CO₂ absorbent.
