Intrinsic Properties of Poly(Ether-B-Amide) (PEBAX®1074) for Gas Permeation and Pervaporation
(University of Waterloo, 2011-06-14)Poly(ether-b-amide) (Pebax® grade 1074) is a waterproof breathable block copolymer containing soft poly(ethylene oxide) and rigid polyamide 12 segments. Its intrinsic gas permeabilities to nitrogen, oxygen, methane, helium, ... -
Nitrogen Removal From Natural Gas by Membrane Separation
(University of Waterloo, 2015-04-08)Canada is globally the third largest natural gas producer with a total production of 13.9 billion ft3/day. Natural gas is a naturally occurring mixture consisting of mainly CH4 and varying amounts of other gases such as ... -
Polydopamine-Based Thin Film Composite Membranes for Pervaporative Concentration of Potassium Acetate Solution
(University of Waterloo, 2022-12-19)Potassium acetate (KAc) is a valuable chemical product due to its widespread application in multiple fields. During the production of KAc, the concentration of dilute KAc solution is a vital pre-treatment procedure to ... -
Remediation of Cellulose Acetate Gas Separation Membranes Contaminated by Heavy Hydrocarbons
(University of Waterloo, 2012-04-04)Polymeric membranes have been essential to increasing the efficiency of membrane separation processes. The viability of membrane systems for industrial gas applications lies in the tolerance of such membranes to contamination. ... -
Reverse Osmosis Desalination and Hybrid Membrane Processes for Brine Treatment
(University of Waterloo, 2019-12-11)Waste from seawater reverse osmosis desalination processes is commonly referred to as brine which is one of the obstacles creating environmental and economic inefficiencies. The objective of this work is to simulate the ... -
Thin film composite membranes via layer-by-layer assembly for pervaporation separation
(University of Waterloo, 2019-12-06)The aim of this study was to develop LbL membranes based on polyethyleneimine and graphene oxide (PEI/GO) and to investigate them for three different applications, namely the pervaporative desalination of high-salinity ...
