that affect a sorbate’s breakthrough behavior. It is common for a plug flow Fickian type model to be used to describe dispersion within a packed bed. However, this does introduce error into the model, since no packed bed has perfect plug flow. By having a better comprehension of the error associated with using plug-flow Fickian models, more rigorous models can be written to better design and optimize adsorption systems. The objective of this dissertation is to contribute to the design of a new air revitalization system for CO2 removal and conversion in spacecraft. Results of the research have ground-based applications in development of process improvements for adsorption and membrane devices including enhanced energy efficiencies. This dissertation is organized as follows. In chapter 2 isotherms are fitted to experimental data for use in sizing a 2-stage TSAC for the capture and pressurization of CO2 in a packed bed of 5A zeolite, which is then later modeled using Comsol Multi-PhysicsTMfinite element software package. The effects of imbalanced heating loads on the desorption of CO2 from a packed bed with an expected value of thermal conductivity are investigated in Chapter 3. Chapter 4 examines nonplug flow of a fluid through a packed bed in which a constant pattern wave has developed for an adsorbent with a slightly favorable isotherm. In chapters 6 and 7 the dehydration of a gas stream is analyzed for a shell and tube Nafion⃝R multi-tube membrane module with the shell side exposed to a vacuum and a counter current purge gas, respectively. 5PDF Image | TEMPERATURE SWING ADSORPTION COMPRESSION AND MEMBRANE SEPARATIONS
