  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • SERVOTOUGH SpectraScan 2400 - A tunable filter optical system for on-line and real-time hydrocarbon gas composition analysis

    Abstract An all-optical sensor platform has been developed for hydrocarbon gas composition analysis enabling speciation and quantification of the individual hydrocarbon components in multi-component matrices of alkanes, alkynes, alkenes and/or alcohols. It performs such speciation without requiring physical separation of the compounds as performed in chromatography. The flow-through ...

  • MonoExact DF150E - Selecting oxygen analysis for reflow furnace applications.

    Maintenance of low oxygen concentration in reflow furnaces produces higher quality product, less product defect, and lower maintenance costs - potentially saving thousands of dollars per year. But only the advent of a unique non-depleting oxygen sensor by Servomex avoids problems with sensor contamination and depletion experienced by traditional sensing technologies. THE ROLE OF OXYGEN ANALYSIS ...

  • Water flow sensor saves school board thousands of dollars - Case Study

    SUMMARY Jessica Kukac is the Environmental & Energy Systems Coordinator with the Simcoe County District School Board (SCDSB). She oversees utility costs and monitors consumption of electricity, water, and natural gas for over 120 schools and public buildings, across 16 different municipalities. After installing the Alert Labs Flowie water flow sensor at one of the schools, she ...

  • Filter damage monitoring with Dusty Ex - Case Study

    Application A chemical manufacturer producing photoinitiators. Photoinitiators are chemical compounds, which disintegrate after the absorption of light in a photolytic reaction. They produce reactive compounds, which are able to initiate a chemical reaction (for example a polymerisation). In praxis these initiators are used to harden lacquers and paints under the infl uence of ...

  • Dust monitoring with ProSens on clean gas side - Case Study

    Application An international mining company extracts minerals under ground for the fabrication of fertilizers. For the long term improvement and safety of the structure stability fi llings and binders (dry bulks) with defi ned recipes are injected locally into former mining cavities. These materials are delivered above ground, stored in silos and afterwards transported in a ...

  • Pegasor AQ Indoor - White Paper

    What needs to be measured from indoor air? Today there is no legislation for indoor air ultrafine particle (UFP) concentration. Particulate matter found indoors will include particles of outdoor origin that migrate indoors and particles that originate from indoor sources. Indoor Particulate Matter (PM) can be generated through cooking, combustion activities (including burning of ...

  • Choosing flow monitors for CEMS applications

    As a result of the 1990 Clean Air Act Amendments1, electric power plants must reduce their emissions of sulfur dioxide and nitrous oxides—the primary causes of acid rain. The U.S. Environmental Protection Agency (EPA), in its proposed rules2, designates the 111 Phase I fossil-fueled plants ^roughly 268 boiler units) that must have continuous emissions monitoring systems (CEMS) installed, ...

  • Multiplexed Monitoring – To be Doubt or Not?

    There are several types of continuous emissions monitoring (CEM) systems. The technical designs may be very different, but they usually have a few things in common. The instruments providing the measurement results do not come cheap, and the systems require maintenance. However, if monitoring is to be done in more than one gas duct, then there might be a way to save costs, multiplexing. But ...

  • How clean is your local air?

    Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations. The equipment used in these stations is very accurate and complies with measurement standards but ...

  • Using a UAV Drone to Monitor Methane

    Recently the use of a UAV drone for gas sensing has become more popular. From monitoring global warming to tracking the spread of pollution, there are many good reasons to want to be able to monitor carbon dioxide, methane and other hydrocarbon gas concentrations even in the most remote, or dangerous, of locations. Leaks in oil pipelines, are not just dangerous because of the explosion risk ...
