Evapoporometry: An Effective Analytical Technique For Membrane Pore Size Characterization Of Hollow Fiber Membranes, Alex J. Moix
Evapoporometry: An Effective Analytical Technique For Membrane Pore Size Characterization Of Hollow Fiber Membranes, Alex J. Moix
Chemical Engineering Undergraduate Honors Theses
A new analytical technique called evapoporometry has shown to be an effective and inexpensive method for membrane pore size characterization. This technique is based on the correlation between vapor pressure and pore size as described by the Kelvin equation. Evapoporometry has many advantages over tradition pore size characterization techniques. This technique allows for large sample sizes, uses minimal equipment, is capable of analyzing membranes within a wide range of pore sizes, and provides a highly descriptive representation of the pore distribution. This research looks at the application of evapoporometry as a technique for characterization of hollow fiber membranes. Using the …

Separation Of Oil From A Brackish Water Stream, Kayli A. Quinton
Chemical Engineering Undergraduate Honors Theses
In the past 40 years, a variety of enhanced oil recovery (EOR) methods have been developed and applied to mature and mostly depleted oil reservoirs. Chemical and sonic stimulation are two enhanced oil recovery methods in which emulsions are created either as a primary or secondary effect. The resulting emulsion viscosity is considerably lower than that of dry crude thus increasing permeability of and recovery from pay zones. During Chemical enhanced oil recovery, caustic or preformed surfactants are injected into oil reservoirs, which results in flooding and periodic breakthrough of stable oil-water emulsions. The emulsions from chemical enhanced oil recovery …
