The Drumbeat on infrared thermal imaging

Drumbeat Energy regards infrared (thermal) imaging as an amazingly useful tool in the quest for greater energy efficiency. It has the ability to define non-invasively and with uncanny speed and accuracy where heat is leaking from a building. Never was the expression “A picture paints a thousand words” ...

Three-dimensional pore networks and transport properties of a shale gas formation determined from focused ion beam serial imaging

Three-dimensional pore network reconstructions of mudstone properties are made using dual focused ion beam-scanning electron microscopy (FIB-SEM). Samples of Jurassic Haynesville Formation mudstone are examined with FIB-SEM and image analysis to determine pore properties, topology, and tortuosity. Resolvable pore morphologies (>~10 nm) include large slit-like pores between clay aggregates and ...

A preliminary study of the application of Background Oriented Schlieren (BOS) for the qualitative imaging of methane emissions from coal

Methane presents a pervasive risk in most coal mines, its dilution being one of the primary objectives of the ventilation system. Although many different types of detectors and techniques exist for quantifying methane, little is known about the qualitative aspects of methane, such as visualising how this gas flows from coal. Background Oriented Schlieren (BOS) provides a potential method from ...

An alternative method to improve the settleability of gas-vacuolated cyanobacteria by collapsing gas vesicles

This study estimated the ability of pressurization to collapse gas vesicles and thereby enhance the settleability of fresh water cyanobacteria. Settling velocities of Pseudanabaena galeata and Microcystis aeruginosa were measured at 11 different pressure values from 0 to 0.5 MPa. The morphological variations that occurred in the gas vacuoles according to the applied pressure ...

Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release

The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester. Methane hydrate, which is also referred to as ...

Advances in gas control technology in the brewery

The use of nitrogen as a process gas, foam enhancer and flavour modifier has come to the fore over the last 10 years, with dissolved gas specifications becoming more stringent. Increasingly, marketing and consumer requirements for a targeted product identity or image have to be met, not only for taste but, perhaps equally as importantly for the consumer, ...

Gas Dilution With The Equal Capillaries Technique

The advantages of the equal capillaries technique are surprising and leads to reach accuracy values of one order of magnitude higher than all the other dynamic dilution techniques. This comparison will be supported by analyzing the accuracy available with two different techniques. Nozzles (sonic or non-sonic) technique With this technique, a series of different size nozzles is used ...

CFD modelling of electrohydrodynamic gas flow in an electrostatic precipitator

Modelling of the flow velocity fields for electrohydrodynamic flow in a wire-to-plate type electrostatic precipitator was achieved. From calculations for the flow employing different flow models, the Chen-Kim k − ε turbulent model appeared to be the most appropriate choice to obtain a quantitative image of the resulting mean flow field and downstream wake flow of the rear wire, although this was ...

Learining how to Choose Materials for Gas Valves

The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the ...

The Measurement of Gas Bubble Size Distributions in a Three Phase Laboratory Gassy Soil

The technique developed can be used to measure the total void, gas void, or particle size distribution in both gassy and saturated sediments provided the void spaces, or particles, can be approximated to spheres. Here the technique is demonstrated for measuring gas bubble size distribution in a reconstituted estuarine silty clay, which has been impregnated with methane gas using the method ...

Development of a novel odor measurement system using gas chromatography

This paper describes a novel odor measurement system for creating arrays of virtual chemical sensors with nonoverlapping responses using ultrahigh-speed gas chromatography with a surface acoustic wave sensor (GC/SAW). This GC/SAW system provides high-resolution twodimensional olfactory images for easy recognition of many complex odors. Separation and quantification of the individual chemicals ...
