  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • Ukraine spotlights German priority: energy switch

    The crisis in Ukraine has added an extra dose of uncertainty to German Chancellor Angela Merkel's biggest domestic project: shifting the country from nuclear to renewable energy sources. Merkel launched the drive to transition the country away from nuclear after Japan's 2011 Fukushima disaster. Since then, the "Energiewende" - roughly, "energy turnaround" - has created increasing headaches. Now, ...

  • Non-contacting solution for Plugged off flow meters in the oil patch - Case Study

    For years Petrobakken Energy Ltd. used inline turbine flow meters to track the flow rate of oil recycled to treaters. But with a high concentration of wax and sand in the oil, the turbine meters were quickly plugging off. The line had to be shut down at least once a day and the turbine flowmeters disassembled for cleaning. This was troublesome and expensive. Petrobakken knew there had to be a ...

  • Drying plastic resin pellets in injection- Molding & Extrusion processes case study

    Application Moisture concentrations are measured in the dry purge air used to remove moisture from a hopper containing plastic resin pellets used in injection-molding and extrusion processes. Problem Moisture contaminates the plastic resin pellets causing several quality problems in the finished plastic products. Moisture causes clear ...

  • How do pressure swing adsorption nitrogen generators work?

    Adsorption is a gas separation process whereby the gas molecules adhere to a surface when under pressure. Adsorption allows for the ability to separate specific gasses, such as nitrogen, from compressed air by selecting an adsorbent material which unwanted gases more readily diffuse into. In the case of air-to-nitrogen separation, compressed air is passed through a cylinder containing a Carbon ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

  • Case study - RTOs leave nothing to HAP-penstance
