Techno-Economic Evaluation of Biological and Fluidised-Bed Based Methanation Process Chains for Grid-Ready Biomethane Production

Tilman J. Schildhauer, Andreas Gantenbein

Three different power-to-methane process chains with grid injection in two scales (1 MWel and 6 MWel) were analysed regarding their investment and operation cost. The process chains were based on biological or catalytic bubbling fluidised bed methanation i ...

Kinetic and mechanistic understanding of chlorite oxidation during chlorination: Optimization of ClO2 pre-oxidation for disinfection byproduct control

Urs von Gunten, Yun Ho Lee

Chlorine dioxide (ClO2) applications to drinking water are limited by the formation of chlorite (ClO2-) which is regulated in many countries. However, when ClO2 is used as a pre-oxidant, ClO2- can be oxidized by chlorine during subsequent disinfection. In ...

Particle size-segregation in granular ows driven by a conveyor belt.

Christophe Ancey, Tomás Alfredo Trewhela Palacios, Kasper van der Vaart

Particle motion within the leading edge of bidisperse gravity-driven granular flows is affected by particle size segregation. Shear-induced segregation causes coarse particles to move towards the upper layers. Then, these are advected down to the tip regio ...

Dual Langmuir-probe array for 3D plasma studies in TORPEX

Ambrogio Fasoli, Ivo Furno, Fabio Avino, Rémy Jacquier, Marcelo Baquero Ruiz, Oulfa Chellaï, Fabian Manke

We have designed and installed a new Langmuir-probe (LP) array diagnostic to determine basic three-dimensional (3D) features of plasmas in TORPEX. The diagnostic consists of two identical LP arrays, placed on opposite sides of the apparatus, which provide ...

Recent advances in liquid water flow modelling in the physics based SNOWPACK model

Michael Lehning, Nander Wever, Sebastian Würzer, Charles Fierz

Simulating liquid water flow in snow has deserved much attention in the physics based snow modelling community, as it is a crucial factor in understanding hydrological processes in alpine catchments, snowpack stratification and wet snow avalanche formation ...

Precise error determination of approximated components in sequential circuits with model checking

Mathias Soeken, Arun Chandrasekharan

Error metrics are used to evaluate the quality of an approximated circuit or to trade-off several approximated candidates in design exploration. Precisely determining the error or all approximated circuit is a hard problem since the errors accumulate over ...

Methane oxidation pathways in Lake La Cruz

Corinne Jegge

Even though lakes only occupy a small percentage of Earth's surface, they represent a natural source of methane, contributing substantially to methane emissions and ultimately to global warming. There is extensive evidence that methane emissions from lakes ...

The Biology/Disease-driven Human Proteome Project (B/D-HPP): Enabling Protein Research for the Life Sciences Community

Martin Kussmann, Ruedi Aebersold

The biology and disease oriented branch of the Human Proteome Project (B/D-HPP) was established by the Human Proteome Organization (HUPO) with the main goal of supporting the broad application of state-of-the-art measurements of proteins and proteomes by l ...
