Exergy Assessment of Single and Dual Pressure Industrial Ammonia Synthesis Units

In exothermic, equilibrium-limited processes such as ammonia synthesis, higher per-pass conversions are often achieved by withdrawing the enthalpy of reaction before the conversion has been completed. However, although inter-bed cooling may help controllin ...

Identification of Multiphase Reaction Systems with Instantaneous Equilibria

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

The identification of kinetic models for multiphase reaction systems is complex due to the simultaneous effect of chemical reactions and mass transfers. The extentbased incremental approach simplifies the modeling task by transforming the reaction system i ...

Competing effects of volume change and water uptake on the water retention behaviour of a compacted MX-80 bentonite/sand mixture

Anne-Catherine Adolphine M Dieudonné

Bentonite-based materials have been studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions (as a consequen ...

Incremental Identification of Kinetic Models by Online Spectroscopy and Multivariate Calibration

Laurent Brandinu

Extent-based kinetic identification is a modeling technique that uses number of moles / concentrations measurements to compute extents and identify reaction kinetics (partial orders of reactions and reaction rate constant) by the integral method of paramet ...

Mixing state and compositional effects on CCN activity and droplet growth kinetics of size-resolved CCN in an urban environment

Athanasios Nenes, Xiuwei Zhang

Aerosol composition and mixing state near anthropogenic sources can be highly variable and can challenge predictions of cloud condensation nuclei (CCN). The impacts of chemical composition on CCN activation kinetics is also an important, but largely unknow ...

Influence of Argon and Nitrogen Admixture in HMDSO/O-2 Plasmas onto Powder Formation

Christoph Hollenstein, Marina Ricci

In situ Fourier transform infrared spectroscopy was used to study the powder formation of hexamethyldisiloxane/O-2 plasmas. The spectra show that oxygen plays an important role at the beginning of the process. A large amount of oxygen is responsible for in ...
