Activation of Delayed and Fluid Petroleum Coke for the Adsorption and Removal of Naphthenic Acids from Oil Sands Tailings Pond Water
DownloadSpring 2011
Oil sands companies produce substantial quantities of tailings known to contain high concentrations of dissolved organic by-products. The use of petroleum coke was proposed as a potential adsorbent for organic contaminant removal from tailings pond water. Physical activation was used to create a...

Adsorbents for the Removal of Naphthenic Acids from Oil Sands Process Water: Investigation of Reclamation Materials from Surface Mining of Oil Sands and Development of Biochars from Biological Sludge and Peat
DownloadSpring 2023
Crominski da Silva Medeiros, Deborah C.
Oil sands process water (OSPW) is generated in high quantities during the extraction of the bitumen from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds, corresponding more than 50% of all organics in OSPW. The efficient management of OSPW is of importance to guarantee efficient...

Adsorption and Microwave Regeneration for Controlling Volatile Organic Compounds Emissions from Automotive Paint Booths
DownloadFall 2016
Adsorption is a widely used method for control of organic compounds produced during painting operations. After adsorption, the loaded adsorbent should be regenerated to recover the adsorbates and reuse the adsorbent for subsequent adsorption/regeneration cycles. Accumulation of non-desorbed...

Application of Anoxic-Aerobic Membrane Bioreactors (MBRs) for Oil Sands Process-Affected Water (OSPW) Treatment
DownloadFall 2016
The enormous volumes of oil sands process-affected water (OSPW) produced during oil sands bitumen extraction have been a public concern due to the toxicity and persistence of the organic contaminants contained in the water. Among all the contaminants in OSPW, naphthenic acids (NAs) are regarded...

Application of Ozone and Peroxone Processes for Naphthenic Acids Degradation in Oil Sands Process-Affected Water: Characterization of Water Before and After Treatment
DownloadFall 2017
Appling ozone (O3) with high doses (>100 mg/L) to remove naphthenic acids (NAs) from oil sands process-affected water (OSPW); limits its application and feasibility in the OSPW remediation. To decrease the required doses and their associated costs, this study examined the application of ozone...

Spring 2023
The increasing abundance of per- and polyfluoroalkyl substances (PFAS) has attracted growing interest due to concern about the potential hazards to public health and ecosystems. Due to PFAS toxicity, mobility, environmental persistence, and strong bioaccumulation, they are being further...

Development and application of Fenton and UV-Fenton processes at natural pH using chelating agents for the treatment of oil sands process-affected water
DownloadFall 2016
The increasing amount of oil sands process-affected water (OSPW), its high toxicity towards aquatic organisms due to naphthenic acids (NAs) and other organics, and the zero discharge practice of the oil sands industry urge researchers to seek effective approaches for its treatment. Advanced...

Effect of Desorption Purge Gas Oxygen Impurity on Heel Formation During Regeneration of Beaded Activated Carbon Saturated with Organic Vapors
DownloadFall 2017
Irreversible adsorption or heel formation during cyclic adsorption/regeneration of high molecular weight volatile organic compounds (VOCs) onto activated carbon decreases its adsorption capacity and lifetime. The effect of regeneration purge gas oxygen impurity on activated carbon performance,...

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...
