A bubble coalescence kernel combining the characteristics of the film drainage, energy, and critical velocity models
(Peer reviewed; Journal article, 2023)A novel coalescence kernel with high predictive properties is constructed to be used within the population balance framework. The kernel includes the product of a collision frequency term and a novel binary coalescence ... -
Capturing CO2 by ionic liquids and deep eutectic solvents: A comparative study based on multi-level absorbent screening
(Peer reviewed; Journal article, 2023)Because of the high energy consumption and volatility of organic amine solvents in conventional CO2 capture processes, ionic liquids (ILs) and deep eutectic solvents (DESs) have been widely expected as alternative CO2 ... -
CO2 capture and utilization by biocatalytic synthesis of carboxylic acids: a process design study
(Peer reviewed; Journal article, 2024)The search for less energy-intensive processes is pushing toward a diversification of Carbon-Capture and Utilization/Sequestration (CCU/S) pathways. Biocatalytic processes offer sustainable solutions characterized by ... -
High-temperature sulfur capture by a Mn-Mo sorbent: An investigation of regeneration conditions and SO<inf>2</inf> formation and prevention
(Peer reviewed; Journal article, 2023)The regeneration performance of a solid sorbent (alumina-supported 15Mn8Mo) for sulfur capture at high temperature has been studied. The regeneration of the sulfided sorbent was performed by oxidizing at different temperatures ... -
Interface mass transfer and properties of bubbly flows in a column with Newtonian and non-Newtonian liquids
(Peer reviewed; Journal article, 2023)The mass transfer of gas–liquid systems is commonly reported through the volumetric mass transfer coefficient, , which is a function of several complex phenomena. To optimize the rate of mass transfer, increased knowledge ... -
Membrane process design for biohydrogen purification with simultaneous CO2 capture: Feasibility and techno-economic assessment
(Peer reviewed; Journal article, 2023)In this work, a membrane separation process is designed and optimized to purify dark fermentative biohydrogen by removing CO2. A CO2-selective PVAm-based nanocomposite membrane was selected considering its high CO2/H2 ... -
Oxidative degradation of triethylene glycol
(Journal article; Peer reviewed, 2024)Triethylene glycol (TEG) is unstable in the presence of oxygen and at high temperatures, though the degradation mechanisms occurring are not properly understood. In attempting to close some of the knowledge gaps, ... -

Predicting solvent degradation in absorption–based CO2 capture from industrial flue gases
(Peer reviewed; Journal article, 2023)This work aims to predict solvent degradation rates in absorption-based CO2 capture processes using a 30 wt% aqueous monoethanolamine (MEA) solvent. A degradation model for MEA is developed and used to predict solvent ... -
Studying droplet retention in porous media by novel microfluidic methods
(Peer reviewed; Journal article, 2022)Transport of oil droplets through porous media is an important topic in the oil and gas industry. Oil droplets that are present in produced water contribute to injectivity decline during re-injection due to retention in ...
