Understanding water vapour adsorption on zeolite pellets

Adsorption of water on molecular sieves is used in several chemical processes and in drying natural gas and carbon dioxide for pipeline transport. Despite the widespread use, our ability to model this process accurately is relatively limited due to the complex mass and heat transfer mechanisms involved. To address this gap in knowledge we intend to develop a new variant of the Zero Length Column technique for the simultaneous measurement of dynamic concentration and temperature responses for zeolite pellets. The plan is to establish the range of temperatures and concentrations where capillary condensation in pellets becomes important. Carrying out experiments below and above these limits we aim to develop a detailed dynamic model capable of predicting both adsorption and desorption rates.

The potential candidate will join the carbon capture group and have access to state-of-the-art experimental and modelling facilities - Carbon Capture at the School of Engineering.

Training will include access to several experimental techniques that can be used to obtain thermodynamic, structural and kinetic parameters for the systems of interest. The final aim of the project is to develop a specific set of models for process simulations based on the group's Cysim adsorption software tool.
