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...

Effect of adsorbate’s polarity, steric hindrance, aromaticity, and boiling point on competitive adsorption in a multi-staged countercurrent fluidized bed reactor using activated carbon and zeolite
DownloadFall 2022
Understanding the multi-component adsorption of volatile organic compounds (VOCs) is of essential importance for real-world engineering applications. Various properties of VOCs can affect their competitive adsorption when there is a mixture of these compounds in the process stream. This thesis...

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...

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...
