Hydrogen purification is an important part of hydrogen energy utilization. This study aimed to perform multi-component gas (H2/CO2/CH4/CO/N2 = 0.79/0.17/0.021/0.012/0.007) by one-column vacuum pressure swing adsorption (VPSA) and (PSA). AC5-KS was selected as the adsorbent for due its greater capacity compared R2030. Furthermore, VPSA PSA 10-step cycle models were established simulate process u...

The complexity of chemical plant systems (CPS) makes optimising their design and operation challenging tasks. This also results in analytical numerical simulation models these having high computational costs. Research demonstrates the benefits using machine learning as surrogates or substitutes for computationally expensive during CPS optimisation. paper presents our study, extending recent res...

Carbon capture is one of the recently raised technologies to mitigate greenhouse gas emissions. Adsorption was introduced as an energy-efficient carbon process, and literature primarily shows utilization circular cross-sectional adsorption beds for this purpose. In regard, paper investigates different shapes adsorbent determine thermal uptake enhancements. Three geometries are considered: circu...

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-...
