Gas shale water imbibition tests with controlled suction technique

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Water loss during flowback operations represents one of the main challenges related to the use of hydraulic stimulation to exploit shale gas resources. About 20% of the injected fracturing fluids are usually recovered after stimulation. Fluid imbibition is ...

Analysis and Removal of Product Gas Contaminants Present in Gasification Processes

Sven Philip Edinger

Energy demand and economic development are intrinsically linked. Earlier economic development came at the price of serious environmental pollution, posing a risk to life on earth. Thus, a transition from fossil to renewable energy is needed. Among the rene ...

VUV/UV light inducing accelerated phenol degradation with a low electric input

Juan Kiwi, Mengkai Li

This study presents the first evidence for the accelerated degradation of phenol by Fenton's reagent in a minifluidic VUV/UV photoreaction system (MVPS). A low-pressure mercury lamp used in the MVPS led to a complete degradation of phenol within 4-6 min. T ...

On-line liquid quench sampling and UV–Vis spectroscopy for tar measurements in wood gasification process gases

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis

In biomass gasification processes, the formation and handling of tars are of major concern. Robust and versatile analytical tools are needed to on-line monitor tar compound concentrations in process gases from lab- to industrial scale. This study addresses ...

Investigating the fate of petroleum fluids released in the marine environment with comprehensive two-dimensional gas chromatography and transport models

Jonas Gros

Anthropogenic releases of petroleum fluids, which contain thousands of compounds, represent a threat to marine environments. However, there was a lack of models able to explain the independent behaviors of the numerous compounds of a spilled petroleum flui ...

The Impact of Toluene on the Performance of Anode-Supported Ni-YSZ SOFC Operated on Hydrogen and Biosyngas

Jan Van Herle, Christian Ludwig, Stefan Diethelm, Hossein Madi

This paper presents an experimental study of the impact of toluene on the performance of anode-supported (AS) Ni/YSZ SOFC operating at ∼800 °C, 0.25 A/cm2 fed with H2 and biosyngas. Toluene was added to the fuel stream and its concentration increased from ...

First day of an oil spill on the open sea: Early mass transfers of hydrocarbons to air and water

Jeremy Samuel Arey, Jonas Gros, Deedar Nabi

During the first hours after release of petroleum at sea, crude oil hydrocarbons partition rapidly into air and water. However limited information is available about very early evaporation and dissolution processes. We report on the composition of the oil ...

Molecular-level characterization of the structure and the surface chemistry of periodic mesoporous organosilicates using DNP-surface enhanced NMR spectroscopy

David Lyndon Emsley, Aaron James Rossini, David Benjamin Roger Antoine Gajan

We present the molecular level characterization of a phenylpyridine-based periodicmesoporous organosilicate and its post-functionalized organometallic derivatives through the fast acquisition of high quality natural isotopic abundance 1D C-13, N-15, and Si ...
