Distributed Temperature Sensing Technology for Stream Monitoring

by Silixa Ltd     based in Elstree, UNITED KINGDOM

Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream ecosystem interfaces provides a mechanism for detailed characterization.

Weather Monitoring Systems for industrial and utility sector

by Climatronics Corporation     based in Bohemia, NEW YORK (USA)

The weather can have a major impact on many industrial processes and operations, both from an operational efficiency and/or safety standpoint. For example, real-time information about ambient atmospheric conditions provides the necessary input data required to make the proper decisions during an industrial emergency involving any type of hazardous material. Depending on the plant type, size and age, the federal Environmental Protection Agency (EPA), as well as municipal and state environmental regulatory organizations, also require that a number of basic meteorological variables are measured and recorded on site to ensure compliance with environmental regulations.

Fluoride emissions monitoring in aluminum smelters

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In addition several fluoride compounds may be produced in the electrolytic bath in the event of an oxygen shortage. These compounds include carbon tetrafluoride CF4, hexafluoroethane C2F6, sulfur hexafluoride SF6, and silicon tetrafluoride SiF4. These additional emission components are problematic, as they have high Global Warming Potential (GWP) values. The GWP is a relative measure designed to demonstrate how much heat a greenhouse gas (GHG) traps in the atmosphere. Emission of one kilogram of carbon tetrafluoride into the atmosphere today has the potential of heating the atmosphere as much as 7,000 kilograms of carbon dioxide over the next 100 years.

Particulate monitoring for continuous emissions

by DynOptic Systems Ltd     based in Brackley, UNITED KINGDOM

With the advent of specific process emission limits being defined, continuous particulate monitoring has become a regulatory requirement for many industries. smoke stack #1Particulate monitoring requires the measurement of the mass concentration of particulate matter in stack emissions to atmosphere. There is no known method of continuously measuring particulate concentration by direct measurement and therefore, all continuous particulate measurement methods are inferential. Each method involves the measurement of a parameter related to particulate concentration and then requires a calibration to be determined to convert the measured value into one of particulate mass concentration.

Gas monitoring instruments and systems for anesthetic gases

by Gasmet Technologies Oy     based in Helsinki, FINLAND

The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.

Gas monitoring instruments and systems for DeNOx process control

by Gasmet Technologies Oy     based in Helsinki, FINLAND

In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

Gas monitoring instruments and systems for greenhouse gas emissions from soil

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Measurement of greenhouse gases released from soil and water surface forms an important part of climate change study. Microbial activity in the soil or for instance the melting of permafrost releases greenhouse gases such as Methane and nitrous oxide N2O into the atmosphere. Measurement of the concentration for these gases inside an open-bottom soil chamber placed on the soil over time tells the emission rate (flux) per chamber footprint area.

Aerosol Research

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The Earth is warmed principally by the sun’s radiation which enters the atmosphere. However, not all the radiation penetrates the atmosphere as some is scattered back into space. The amount of back-scattering into space alters the amount of energy that is absorbed into the atmosphere. backscattering of this energy provides valuable information on the change of the earth’s radiation balance and how different activities (artificial and anthropogenic) can affect this delicately balanced system and thus influence global warming

Greenhouse gases monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Greenhouse gases are gases in the atmosphere which absorb and emit radiation within the thermal infrared range. Changes in the concentration of these gases due to both man made and natural effects increase the risk of global climate change.
