Simulation and analysis of xenon removal system through gas sparging in molten salt reactor
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

Effects of hydrogen in an aluminium-magnesium-silicon alloy during the production of extrusion ingots
… the composition is adjusted, the metal is degassed by gas sparging and allowed to settle before casting. The metal cools throughout these operations and as the temperature falls, the calculated value for the hydrogen content in equilibrium with the atmosphere falls in response to the reduced …

Transverse vibration as a fouling limitation strategy in membrane bioreactors
… that observed with crossflow velocity (CFV) or gas sparging under similar flow conditions. It was also found that the fouling which occurred during filtration with vibration was more reversible than that incurred with CFV and gas sparging. Filtration performance with transverse vibration was …

Enhancing CO2 mass transfer in algal raceway ponds through wave generation
… energy and resource intensive alternative to CO2 gas sparging. Depending on the design, the slope can either act like a beach, to mimic the formation of shoaling ocean waves, or act like a weir to create a hydraulic jump. This study aimed to shed light on the effect of different slope parameters …

Elucidating the relative environmental sustainability of anaerobic membrane bioreactor (AnMBR) development pathways
… the principal source of life cycle impacts (gas sparging) and achieve the most en- vironmental sustainable design. The significance of the roadmap developed in this study is its nature as a blueprint for the future research development and design of AnMBR technology.

Enhancing Gas Absorption with Nanoengineered Surfaces for Bubble Manipulation
Efficiently reacting gases with liquid absorbents is a crucial aspect of numerous industrial processes on a large scale. When the gas phase is in the form of discrete bubbles within an absorber unit, such as in bubble column absorbers or gas sparging systems, the effectiveness of these bubbles' …

Tritium production analysis and management strategies for a Fluoride-salt-cooled high-temperature test reactor (FHTR)
… is the primary radionuclide in liquid and gaseous tritium release. Light water reactors release up to several hundred curies per year for which various tritium removal and control strategies have been developed and implemented. Using the ORIGEN-S code analysis, tritium production for the …

Production of biopolymer using a membrane-based bioreactor
Methane is a potent greenhouse gas produced from natural gas reservoirs, landfills, and anaerobic digesters. Some methanotrophic bacteria produce intracellular polyhydroxybutyrate (PHB) in the absence of nitrogen and presence of methane and oxygen. In this study, Colorado School of Mines (CSM) and …

Anaerobic Fermentation of Food Waste and Glycerol to Hydrogen
… A less studied process to increase yield is sparging with low-H<sub>2</sub> content gas to strip H<sub>2</sub> from the digester liquid. The present study optimized the levels of each of these variables for hydrogen production from glycerol and food waste, building on previous …
