CH4 Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4 analyzer that is able to provide continuous monitoring is a perfect solution for this.

Coming from a scientific environment and further engaged in long term co-operation with universities and institutions, the company has been involved in several oil and gas projects, piloting the use of point sensors for continuous monitoring of gas leakages.

Measurement solution for soil chamber gas flux

by Protea Limited     based in Middlewich, UNITED KINGDOM

Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such as after the spreading of liquid manure, and steps are required to measure and reduce the NH3 emissions and the effects they have on the ecosystem.

Methane gas leak detection

by Opgal Optronic Industries Ltd.     based in Karmiel, ISRAEL

Methane emissions from oil and natural gas systems is primarily the result of normal operations or system disruptions. These hazardous emissions can be cost-effectively reduced by upgrading technologies or equipment, and by improving operations. However, in order to do so, one must be able to detect and identify the existence of a fugitive gas leak. Opgal`s EyeC Gas Thermal Imager for gas leak detection, is one of the most advanced cameras used to detect leaks. Thus, it becomes a required tool in mitigating and reducing fugitive emissions of methane gas.

Measurement of methane, methanol and ethanol for the biomass monitoring for biofuels.

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Series 8900 provides direct measurement of methane, methanol, and ethanol for the biofuel industry. The Series 8900 GC employs a flame ionization detector (FID). The methane, methanol, and ethanol in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the MME and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Methane, methanol, and ethanol are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Methane Sensing for Coal Mining

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Application: The majority (around 60%) of the coal seams currently being extracted worldwide are so far underground that open cast mining cannot take place and, therefore, underground mining techniques need to be used. Consequently, workers have to enter and work in confined spaces. One of the major problems that this creates is the dangers from Methane (CH4) gas which occurs in Mine gas.

Single Gas Monitoring - Pipeline Monitoring

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Application: measurements of single gas species over pipeline or similar extremely long emission source. Application: measuring CH4 emissions from a natural gas pipeline through a large densely populated and congested area.

Noise monitoring solutions for noise source identification

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Before you can determine what design changes are appropriate to reduce the noise emitted by a product, you need to be able to characterise it in terms of: Spectral content: The location of the dominant sources. The relative importance of dominant sources. Noise Source Identification employs a number of tools to perform such a characterisation.

Gas Detection Solutions for Pipeline Leak Detection

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Natural gas pipeline owners require improved routine monitoring of pipelines for safety, economic and regulatory reasons. Leaking natural gas can cause explosions leading to loss of life and property. Loss of product through undetected leaks dramatically reduces a pipeline operator’s profitability.

Oxygen Monitoring from Aerobic and Anaerobic for Biodegradation Assessments

by Respirometer Systems and Applications, LLC     based in Springdale, ARKANSAS (USA)

Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample. 

Sensor for Biogas

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Anaerobic Digestion plants produce various gas components from a source material (or feedstock) that can be composed either solely or as a mixture of slurries, purpose-grown crops, food and organic waste material. The composition of the gas produced varies depending upon the feedstock and the Anaerobic digestion process itself. As a consequence, it is normal to measure various components of the resultant gas produced to evaluate the efficiency of the Anaerobic Digestion process. Furthermore, due to the flammable nature of Methane (CH4), and the risk of asphyxiation, most plants feature ambient air monitoring to protect personnel from any unplanned accumulation of leaked gas. CH4 is the gas component fuel, which is the intended end product of the anaerobic digestion process. In biogas plants, the concentration of CH4 in a working plant varies between 50%-75%, which is well above the Upper Explosive Limit (UEL).

Single Gas Monitoring - Variable Locations

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Application: Measurements of a single gas in variable locations. Example: the detection of CH4 hotspots in landfill.

Measurement of methane and non-methane hydrocarbons for environmental air quality.

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Model 8900 Methane/Non-Methane Analyzer provides direct measurement of Methane and Non-Methane Hydrocarbons. This instrument is utilized in ambient air monitoring networks around metropolitan areas, fence-line monitoring at industrial plants and hazardous waste sites, and in the production of high purity industrial gases. Methane is a naturally occurring gas generated from the decomposition of biological materials and industrial activity. Since Methane is not considered a pollutant it is the Non-Methane hydrocarbons that are of primary concern.
