Gas Separation by Poly(ether block amide) Membranes

Liu, Li (University of Waterloo, 2008-04-16)

This study deals with poly(ether block amide) (PEBA) (type 2533) membranes for gas separation. A new method was developed to prepare flat thin film PEBA membranes by spontaneous spreading of a solution of the block copolymer ...

Nitrogen Removal From Natural Gas by Membrane Separation

Wu, Kai (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 ...

Separation of Phenols and Aniline from Water Streams using Poly(ether-block-amide) Membranes

Cao, Xiaotong (University of Waterloo, 2021-10-14)

Phenols and aniline are aromatic compounds in which a hydroxyl group and amine group are attached to the benzene ring, respectively. Both are common organic pollutants in a wide range of effluents from such industries as ...

Separation of Volatile Organic Compounds from Nitrogen by Hollow Fiber Composite Membranes

Liu, Yujing (University of Waterloo, 2003)

Many industrial processes handling organic solvents produce volatile organic compounds (VOCs). These VOCs not only cause environmental pollution, but also represent an economic loss. VOC removal and recovery have ...

Sorptive Removal of 4-Aminophenol from Water Using a Polymeric Sorbent

Celarek, Michael (University of Waterloo, 2017-09-27)

This study deals with isotherm, kinetics and mechanistic studies pertaining to the sorption of 4-aminophenol from water using poly(ether-block-amide) (PEBA). A combined Langmuir and Freundlich isotherm model is used to ...

Sorptive separation of phenolic compounds from wastewater

Lai, Shuixiu (University of Waterloo, 2017-04-28)

This study explores the potential of using PEBA as a sorbent for removing phenolic compounds from wastewater. The sorption isotherms of phenol, 4-chlorophenol (4-CP), 4-nitrophenol (4-NP), 4-methylphenol (4-MP) and catechol ...
