Characterization of natural zeolite membranes for H2/CO2 separations by single gas permeation
DownloadFall 2011
Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

The fluids produced from a thermal enhanced recovery process such as steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) are pumped to the surface where bitumen and water are separated. This initial fluid is known as SAGD-PW (produced water). A potential way to effectively...

Natural zeolite-based membranes have recently shown promise in the separation of H2 from CO2 and hydrocarbons. However, these highly dense, naturally monolithic materials can suffer defects which disrupt the continuity of the zeolite micropores and create leak paths through the membrane. Cement...

Natural Clinoptilolite Composite Coated Stainless Steel Tubular Membranes for Water Softening and Desalination
DownloadSpring 2015
Water is an essential resource for life and sources of fresh water are limited. As population and industries are increasing around the world the need for reuse the water is increased. One of the most important industries in Alberta, Canada is oilsands industry. Steam assisted gravity drainage...

Separation of Hydrogen and Carbon Dioxide from Syngas Using Clinoptilolite Natural Zeolite and Ordinary Portland Cement Composite Membranes
DownloadSpring 2014
Separating hydrogen and carbon dioxide from syngas is a necessary step for many industrial processes. Membrane separations are an attractive solution as they can operate at process temperatures (200-500 °C) and operate with a simple process. Pure thermally stable (up to 600 °C) clinoptilolite...
