Characteristics of Aminosilicones Used for CO2 Capture

This work describes the characterization of the material and CO₂ absorption characteristics of a new class of CO₂ absorption liquids. Mixtures of aminosilicones and hydroxyethers were shown to have improved dynamic CO₂ capture capacities compared to more common CO₂ capture solvents such as 30% MEA. Isotherms and other measured properties were used to calculate the cost of electricity using a CO₂ capture system model integrated into a pulverized coal-fired power plant system. Systems for study in a lab-scale continuous absorption / desorption apparatus were based on these results.
