    The Customer The Company is one of the world’s leading developers and producers of advanced fuels and green chemicals. The Process The Company uses a gasification process that breaks down wood chips, waste and other feedstock using plasma technology. The process produces a uniform synthetic gas (syngas) that is used to power their turbine engines. ...

  • Development of on-line and field dual TD GC – MS for automatic VOC monitoring on petrochemical sites

    Ambient air is polluted by many semi-Volatile and Volatile Organic Compounds (SVOCs and VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from pg/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform ...

  • Water Quality Monitoring for the “Big Four Parameters”

    Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates. For most water ...

  • Planning for a Gas Monitoring System

    Do you need a gas monitoring system? Then you already know which gases you want to monitor, you probably have an idea of measurement ranges and accuracy requirements, and perhaps you have a budget for the system. But which other aspects have to be considered, and how do you actually design the system? ...

Then you already know which gases you want to monitor, you probably have an idea of measurement ranges and accuracy requirements, and perhaps you have a budget for the system. But which other aspects have to be considered, and how do you actually design the system? Whether it is about air quality monitoring, continuous emissions monitoring or process control, ...

  • Stack gas VOC monitoring

    POLLUTION S.r.l. manufactures POLARIS FID analyzer, a cutting-edge technology for the measurement of total hydrocarbons in ambient air and stack emission monitoring in accordance with EN 13526 and EN 12619. This analyser is based on Flame Ionization Detection (FID), a reference method technique to measure total hydrocarbons (THC, VOC, TOC). Polaris FID is a very handy instrument because it allows ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • A Four Channel Gas Detector for Wastewater Treatment Plants

    Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...

  • What is the Difference between a gas analyser and a gas monitor?

    Technically, there does not have to be any difference at all. However, semantically, “analysis” might suggest something more scientific with higher precision and better performance than a simple “monitor” which possibly suggests a more indicative output where precision is of less importance. With that said, the two words “analyser” and “monitor” are ...

  • 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 ...

  • Green House Gas Flow Monitoring

    This article addresses the challenges and solutions to flow measurement of green house gases in various industry applications.  GHG flow monitoring regulations are discussed and addressed. Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year ...

  • FTIR gas monitor for diverse applications

    QUANTITECH, a leading supplier of environmental monitoring instrumentation, has recently supplied EURO Environmental Services in Ireland with a transportable Gasmet FTIR multiparameter gas analyser which EURO Environmental's Managing Director Geoff Fitzpatrick says, “is proving invaluable in many varied applications across a broad selection of industries.” With headquarters in Drogheda in Ireland ...

  • 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 ...

  • Laser gas detector systems for greenhouse gas emissions monitoring

    Two types of portable laser based gas detector for measuring emissions of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from oil and gas operations are described. A scanning open path detector was developed within a Cooperative Research and Development Agreement (CRADA) with the USEPA. This system scans multiple paths across an area source in rapid succession, enabling calculation ...

  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • Electrochemical Sensors for Specific Gas PPM Monitoring

    Echem sensors are able to read a specific gas even when it is mixed in a background of other gases. Echem sensors are typically used to read very low PPM concentrations of toxic gases. The Echem sensor consists of a small cell holding an electrolytic solution. This solution needs a specific gas in order to produce an electrical signal. When the specific gas passes through a permeable membrane and ...

  • Gas Monitor Bump Testing vs Calibration

    We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...
