Effect of Purge Gas Flow Rate and Oxygen Impurity on Heel build-up and Prediction of Heel build-up Using Machine Learning
DownloadFall 2021
Heel buildup, i.e., the accumulation of non-desorbed/non-desorbable adsorbates and their by-products on an adsorbent, during cyclic adsorption/regeneration of volatile organic compounds (VOCs) onto activated carbon decreases its adsorption capacity and lifetime. In this this study, the effect of...

Effect of Surface Oxygen Groups on Irreversible Adsorption of Volatile Organic Compounds on Beaded Activated Carbon
DownloadSpring 2017
Adsorption by activated carbons is a widely used method for controlling emission of volatile organic compounds (VOCs). However, accumulation of adsorbates and/or regeneration by-products (heel buildup) during cyclic process is a common challenge in this process. Irreversible adsorption restricts...

Effects of Adsorbate Properties on Heel Buildup on Activated Carbon Fiber Cloth during Electrothermal Regeneration
DownloadSpring 2017
Automotive painting booths are a major source of volatile organic compounds’ (VOCs) in the automotive manufacturing sector. Adsorption on activated carbon (AC) has been widely used as a low cost and energy efficient VOC control method. A major challenge associated with the cyclic...

Forward Osmosis as an Approach to Manage Oil Sands Produced Water: Membrane Fouling and Organic Removal
DownloadFall 2017
Currently, large amounts of oil sands process-affected water (OSPW) are stored in tailing ponds, leaving its environmental impact a significant concern. To better manage OSPW, numerous treatment approaches have been investigated including adsorption, advanced oxidation and biological treatment,...

Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...

Modeling the Performance and Hydrodynamic Behavior of a Countercurrent Multistage Fluidized Bed Adsorber
DownloadSpring 2021
Fluidized bed (FB) adsorbers provide excellent gas-solid contact at low pressure drops which allows for effective handling of large flow rates. However, the design, operation, and modeling of FB adsorbers could be challenging due to the complex processes involved. The goal of this research is to...

Phase Behavior, Adsorption Behavior and Interfacial Properties of Fluids in Shale Reservoirs
DownloadFall 2018
Shale oil/gas resources are becoming an increasingly important energy resource. Compared to conventional reservoirs, shale generally consists of a large proportion of organic matters. Organic matter is mainly comprised of kerogen, within which a significant amount of nanopores may reside. Due to...

Spring 2013
Coagulation/Flocculation/Sedimentation (CFS), petroleum coke (PC) adsorption, and zero valent iron (ZVI) oxidation-enhanced by PC were applied for the remediation of oil sands process-affected water (OPSW), generated from oil sands operations in northern Alberta, Canada. OSPW is a complex mixture...

Production and Application of Different Waste-derived Sustainable Materials for the Removal of Naphthenic Acids Related to Oil Sands Process Water
DownloadSpring 2024
Oil sands process water (OSPW) is generated in a large volume during the bitumen extraction process from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds that contribute to the toxicity of OSPW, which need effective treatment before being released into the environment. In the...

Reclamation of Unconventional Oil Processed Water through the Adsorption of Naphthenic Acids by Carbon Xerogel
DownloadFall 2017
This study examines the use of carbon xerogel (CX) material for the adsorption of naphthenic acids (NAs). The adsorption of NAs is crucial for the reclamation of unconventional oil processed water, more specifically Alberta’s oil sands process-affected water (OSPW). CX material is synthesized at...
