Plasmonic Pervaporation For Sustainable Mixture Separation, Ty Austin
Chemical Engineering Undergraduate Honors Theses
The U.S. Department of Energy suggests that ca. 40% of the total energy consumed in the chemical and refining industries is used for distillation.1 One potentially energy efficient alternative is pervaporation, a membrane separation process that uses differences in solvent permeability and vaporization rates to encourage mixture separation. Pervaporation has become a valuable tool in the processes of producing biofuels, recovering water, and removing solvent.2,3 However, implementation has been hindered by heating the feed to the membrane and cooling the unpermeated retentate to increase membrane throughput at a higher energy cost. Preliminary research has shown that locally heating …

Hollow Fiber Membranes For Artificial Lung Applications, Lauren Reed
Chemical Engineering Undergraduate Honors Theses
Artificial lungs are in use, but difficult issues remain in the field of membrane development related to fouling issues. Currently there are external artificial lungs circulating blood outside the body, taking out the carbon dioxide, and inserting oxygenated blood back into the body. An example of this type of machine is the ExtraCorporeal Membrane Oxygenation (ECMO) machine currently used in hospitals. The ECMO takes over the functions for both the lungs and the heart but is only available for short term use by patients with respiratory failure due to infections [1]. The fibers in the machine develop fouling due to …
