  • Technical and economic analyses of a hydrogen-fed gas turbine with steam injection and co-generation

    Enel has been working on a hydrogen programme dealing with both hydrogen production and uses. The first phase deals with a hydrogen-fed, gas turbine-based co-generative cycle, in which steam injection in the gas turbine itself is adopted in order to couple high process efficiencies with very low nitrous oxide emissions. This paper presents the main results of the co-generative cycle thermodynamic ...

  • Gas analysers support management of Swindon fire

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency ...

  • High Resolution Detailed Hydrocarbon Analyses by Capillary Column Gas Chromatography

    In the petrochemical industry, samples such as petroleum naphthas and gasolines routinely must be quantitatively separated into their individual components.  Because these petroleum-derived samples consist of hundreds of compounds, petroleum analysts require chromatography columns that offer high resolution.  We have developed polar and nonpolar capillary gas chromatography columns to ...

  • GC Analyses of Polynuclear Aromatic Hydrocarbons

    Polynuclear aromatic hydrocarbons (PAHs) can be separated by packed column or capillary column gas chromatography. An SPB-5 bonded phase fused silica capillary  column separates the 16 PAHs considered priority pollutants in wastewater by the US Pal SP-301, a liquid crystal stationary phase in packed GC columns, resolves benzo(e)pyrene and benzo(a)pyrene. This publication discusses ...

  • Case study - Geotech’s first GA5000 landfill gas analyser takes 100,000 readings for SUEZ environnement

    Geotech’s first GA5000 analyser, manufactured three years ago, was recently spotted in the company’s calibration rig.  This portable landfill gas monitor was the first production unit of the newly launched GA5000 gas analyser range and has prompted Geotech to look into the analyser’s life since then. The analyser was on its sixth service since manufacture, under ...

  • Emissions analyser helps manage power station

    A multiparameter emissions monitor at Thetford power station is being used to demonstrate to the Environment Agency that the plant is performing within the conditions of its environmental permit. However, the data from the analyser, which was supplied by Milton Keynes based Quantitech, also performs a vitally important role in helping to manage the plant. “Individual gas readings are ...

  • SPME/GC Analyses of Sulfur Gases and VOCs, Using a Carboxen/PDMS Fiber

    Sample extraction of sulfur compounds and VOCs by traditional methods can be difficult and expensive. Typically, sulfur analysis requires concentration of the gas using adsorbent tubes containing carbon adsorbents. Analysis by such means, however, requires the use of an expensive thermal desorption unit to heat the tubes before transferring the gases to a gas chromatograph. Analysis of VOCs ...

  • Influence of trade on national CO2 emissions

    International trade has an impact on national CO2 emissions and consequently on the ability to fulfil national CO2 reduction targets. Through goods and services traded in a globally interdependent world, the consumption in each country is linked to greenhouse gas emissions in other countries. It has been argued that in order to achieve equitable reduction targets, ...

  • Market integration for natural gas in Europe

    In this paper, we examine the degree of market integration in French gas imports. Are there substantial price differences between gas from different export countries, and do prices move together? Furthermore, we analyse to what extent the French, German and Belgian markets are integrated. The long-term take-or-pay contracts are described and analysed. Time series of Norwegian, Dutch and Russian ...

  • Analyses of Permanent Gases, Light Hydrocarbons, and Light Polar Compounds, Using Packed Column GC

    GC columns containing Carboxen-1000 packing separate mixtures of permanent gases (nitrogen, hydrogen, oxygen/argon, carbon monoxide, carbon dioxide) and C1-C3 light hydrocarbons (methane, acetylene, ethylene, ethane, propyne, propylene, and propane). A 15’ x 1/8” column will separate the permanent gases and C1 and C2 hydrocarbons in less than 25 minutes. A 2’ x 1/8” column ...

  • The world gas market in 2030 – development scenarios using the World Gas Model

    We discuss potential developments of the world natural gas industry through 2030. We use the World Gas Model (WGM), a multi-period strategic representation of the global natural gas sector, between 2005 and 2030. We specify a 'base case' and then analyse the sensitivity of the world natural gas system with scenarios, including various supply scenarios (e.g., emergence of large volumes of ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

  • Exhaust gas treatment by an atmospheric pressure microwave plasma

    A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...
