The Dynamic Response and Characteristics of an Oxygen Vacuum Swing Adsorption Process to Step Perturbations. Part 1. Open Loop Responses

Oxygen vacuum swing adsorption (VSA) has emerged as an important unit operation in many chemical engineering processes such as iron and aluminium smelting, making oxygen the third largest man-made chemical commodity in the world. Although a mature technology (with the first patents published in the...
