Zhang, Yuxuan (author), Zhai, Xiaoqiang (author), Zhang, Fengyuan (author), Zhang, Zhongbin (author), Hooman, K. (author), Zhang, Hai (author), Wang, Xiaolin (author)Enhancing gas-liquid mass transfer is key to promote gas hydrate formation kinetics. Encapsulation of CO<sub>2</sub> hydrate is expected to dramatically increase gas-liquid contact to enhance mass transfer. However, gas hydrate encapsulation has never been proposed as the technical issues of gas permeation through capsule shells have never...journal article 2023

Fluttert, Bob (author)The Intergovernmental Panel on Climate Change (IPCC) believes that multiple solutions must be deployed simultaneously to reduce the emission of greenhouse gases into the atmosphere. Carbon, Capture & Storage (CCS) is an unavoidable technique within this portfolio as an intermediate solution. CCS requires transport of CO<sub>2</sub> through...master thesis 2022

van Linden, N. (author), Wang, Yundan (author), Sudhölter, Ernst J. R. (author), Spanjers, H. (author), van Lier, J.B. (author)Recovery of ammonia (NH<sub>3</sub>) from residual waters offers various reuse opportunities, such as the production of fertilisers and the generation of electricity and heat. However, simultaneous evaporation of water (H<sub>2</sub>O) during NH<sub>3</sub> stripping under vacuum results in diluted recovered NH<sub>3</sub> gas with high H<sub...journal article 2022

Puiman, L. (author), Abrahamson, Britt (author), van der Lans, R.G.J.M. (author), Haringa, C. (author), Noorman, H.J. (author), Picioreanu, C. (author)Mass transfer limitations in syngas fermentation processes are mostly attributed to poor solubility of CO and H<sub>2</sub> in water. Despite these assumed limitations, a syngas fermentation process has recently been commercialized. Using large-sale external-loop gas-lift reactors (EL-GLR), CO-rich off-gases are converted into ethanol, with...journal article 2022

Bagemihl, I. (author), Bhatraju, C. (author), van Ommen, J.R. (author), van Steijn, V. (author)Electrochemical reduction of CO<sub>2</sub>using renewable energy is a promising avenue for sustainable production of bulk chemicals. However, CO<sub>2</sub>electrolysis in aqueous systems is severely limited by mass transfer, leading to low reactor performance insufficient for industrial application. This paper shows that structured reactors...journal article 2022

(author)In gas fermentations (using O2, CO, H2, CH4 or CO2), gas-to-liquid mass transfer is often regarded as one of the limiting processes. However, it is widely known that components in fermentation broths (e.g., salts, biomass, proteins, antifoam, and organic products such as alcohols and acids) have tremendous impact on the volumetric mass transfer...journal article 2022

Simmes, Wout (author)As the world population is increasing and cities grow faster than before, food scarcity becomes a bigger issue. To depend less on import and decrease CO2 footprint, food should be produced nearby its consumers. A good solution for food production is a greenhouse which provides a steady high yield throughout the year. Some of the world's fastest...master thesis 2021

Krikke, i.r.c. (author)During water electrolysis for the production of hydrogen and oxygen, many bubbles are formed at the electrodes. The presence of these bubbles causes a number of side effects such as a significant increase in the total cell resistance (e.g., electrical circuit resistances, transport related resistances, and electrochemical reaction resistances)....master thesis 2021

(author)Syngas fermentation to biofuels and chemicals is an emerging technology in the biobased economy. Mass transfer is usually limiting the syngas fermentation rate, due to the low aqueous solubilities of the gaseous substrates. Membrane bioreactors, as efficient gas–liquid contactors, are a promising configuration for overcoming this gas-to...review 2021

Hendrix, Emile (author)Ventilation events are the result of masses of air being transported from the water surface along the hull, through the propeller plane. Previous research in literature has shown that ventilation induces large and sudden variations of the load on the propeller. The response of the propulsion system had not been documented before. This is a...master thesis 2020

Ahmad Mohammad Tahir, Ahmad (author)The hot water produced from a geothermal doublet possesses energy, which once utilized, the water cools down and is re-introduced back into the same reservoir at a sufficient distance using an injector well. As cold water flows through the reservoir, it acquires thermal energy from surrounding in-situ rocks. This process recurs until a...master thesis 2019
