GPS-enabled gas analyser finds & proves borehole locations case study
Prove it? They can now! Landfill technicians and environmental consultants can now find and prove borehole locations with a GPS-enhanced portable gas analyser from Geotech. Its on-board GPS guidance system takes staff to the precise location of the 1000 it can store. It adds the GPS-received location, date and time to the gas analysis record. GPS locations can be added at boreholes or pre-loaded ...

Measuring and interpreting gas flow from landfill boreholes case study
Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the 'flow' ...

Flow measurement technology comparison: GA5000 Vs Hot Wire Anemometer
A typical landfill or contaminated land site under investigation will comprise of a suitable number of gas monitoring wells, with a planned series of monitoring visits. The monitoring will include gas flow measurements, which together with methane and carbon dioxide concentrations will be used to calculate gas screening values (GSV) and hence allow the determination of whether any gas protective ...

Measurements of Methane Emissions and Surface Methane Oxidation at Landfills: WR1125
Methane emissions from landfill were estimated to account for around 3% of the UK‟s total greenhouse gas emissions in 2009. The reported figure for methane emissions from landfill in the UK represents 41.5% of all UK methane emissions. The IPCC guidelines indicate that measurement of methane emissions is necessary to validate models and to provide confidence in country specific model ...

Portable Remotely Operated Drill (PROD): Hydrocarbon Sensing System
Proven Technology Benthic’s prototype Hydrocarbon Sensing System (HSS) analyses drill returns for the presence of hydrocarbons as they pass through PROD before being vented on the seafloor. The System, in its present form, includes two hydrocarbon sensors in line with the drill returns path. Drill returns, composed of seawater drawn from above PROD and pumped down the drill hole, mixed ...

Linde Statoil Snøvhit - Microfiltration plant cleans glycol-water mixture generated by natural gas production - Case Study
Snøvhit (in English – Snow White), or Snøvhitfeltet, is the fifth largest Norwegian gas field - operated by the Statoil Group. There are considerable gas reserves there, in the Barents Sea off the coast of Northern Norway. The gas is transported using pipelines laid on the seabed to the treatment plant located on an island. There, the gas is converted to liquid gas (LPG). A ...

The latest ground Gas monitoring innovations
The latest Ground Gas monitoring innovations The traditional methodology for ground gas monitoring has been ‘spot monitoring’ – taking event readings at various set times to predict the sub surface gas regime on both on Brownfield and Landfill sites. This methodology is in general current practice under both the EU Landfill Directive 1999/31/EC which is supported by ...
