A combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transition in LNG spills
The influence of concentration and temperature on the membrane resistance of ion exchange membranes and the levelised cost of hydrogen from reverse electrodialysis with ammonium bicarbonate
Electrodialysis in Hydrometallurgical Processes
Electrodialysis (ED) is an ionic exchange membrane process for separation of different components and species. In desalination, a large part of the energy is used to sustain a concentration difference between the solutions, but in the processes of exchanging in selective manners, the energy need is...

Dissecting the exergy balance of a hydrogen liquefier: Analysis of a scaled-up claude hydrogen liquefier with mixed refrigerant pre-cooling
For liquid hydrogen (LH2) to become an energy carrier in energy commodity markets at scales comparable to for instance LNG, liquefier capacities must be scaled up several orders of magnitude. While state-of-the-art liquefiers can provide specific power requirements down to 10 kWh/kg, a long-term...
Bulk and interfacial thermodynamics of mixtures: From ultracryogenic fluids to aqueous systems
Minimum entropy production in a distillation column for air separation described by a continuous non-equilibrium model
In this work, we apply the rate-based model of Taylor and Krishna to describe the separation of air in a low-pressure, packed distillation column. By use of numerical optimization, we identify the temperature profile for heat exchange with the column and its surroundings that minimizes the total...
The influence of interfacial transfer and film coupling in the modeling of distillation columns to separate nitrogen and oxygen mixtures
Accurate quantum-corrected cubic equations of state for helium, neon, hydrogen, deuterium and their mixtures
Cubic equations of state have thus far yielded poor predictions of the thermodynamic properties of quantum fluids such as hydrogen, helium and deuterium at low temperatures. Furthermore, the shape of the optimal α functions of helium and hydrogen have been shown to not decay monotonically as for...
