Modeling of Vacuum Temperature Swing Adsorption for Direct Air Capture Using Aspen Adsorption

The paper evaluates the performance of an adsorption-based technology for CO2 capture directly from air at industrial scale. approach is based on detailed mass and energy balance dynamic modeling vacuum temperature swing adsorption (VTSA) process in Aspen Adsorption software. first step aims to validate thanks published experimental data a lab-scale bed module terms transfer packed using amine-functionalized material. A parametric study main operating conditions, i.e., velocity, relative moisture, temperature, rate, undertaken assess global consumption. method up-scaling exposed performances are provided. scale up lab size conservative thermal consumption while electrical very sensitive design. Further related engineering solutions available reach high gas velocity required. This could be offered by monolith-shape adsorbents.
