Simulation of adsorption and desorption of VOC on activated carbon

Abstract

The study's primary purpose is to simulate the adsorption and desorption of volatile organic components on activated carbon bed using python. The model was verified with experiments for the separation of methane (55 mol %) - carbon dioxide (45 mol %) mixture using vacuum pressure swing adsorption on an activated carbon molecular sieve. For a six-component mixture (methane, ethane, propane, butane, carbon dioxide and nitrogen), the model was verified using Aspen Adsorption flowsheet simulator and experimental results of vacuum pressure swing adsorption on activated carbon. Even though the model showed a relatively low error in comparison with provided experiments, some experimental cases need to be investigated more to get a better model prediction.
