A Psa Process For An Oxygen Concentrator, Aaron A. Moran Jan 2014

A Psa Process For An Oxygen Concentrator, Aaron A. Moran

ETD Archive

Oxygen is used in a variety of chemical processes and for medical purposes throughout the world. Pressure swing adsorption (PSA) has become a viable alternative to cryogenic distillation for the separation of oxygen from air with the development of advanced adsorbents like zeolites. PSA processes are inherently complex because it is a dynamic process. Efficient operation of a PSA process is necessary in order to utilize the capacity of the adsorbent as much as possible and reduce the power requirements of the process.In this thesis, a novel zeolite adsorbent was utilized in a PSA process for oxygen generation with ...


Pure Component Adsorption Of Methane, Ethylene, Propylene And Carbon Dioxide In Silicalite, Qianqian Zhou Jan 2013

Pure Component Adsorption Of Methane, Ethylene, Propylene And Carbon Dioxide In Silicalite, Qianqian Zhou

ETD Archive

Adsorption isotherms are measured for pure methane, ethylene, propylene and carbon dioxide in silicalite. Isotherm data are collected using a volumetric method at three different temperatures of 10C, 35C and 65C at pressure up to 100psi. The Virial equation and Langmuir equation have been applied to represent excess amount adsorbed in each pure component system. The binary adsorption equilibrium for various mixtures are predicted from the pure component adsorption data, using the Ideal Adsorption Solution Theory (IAST)
