Particle Size Monitoring Applications

  • Odour removal units for professional kitchen ventilation

    Our company has odour removal units for professional kitchen ventilation, for grills and food preparation areas generally. The operation of the unit is based on chemical or electrostatic filters or a combination of both. The kitchen unit KDSA (with chemical filters) series, neutralizes particles, soot, odors, grease and moisture completely. KDSA units for kitchen ventilation are installed in the cooker hood and are connected with the kitchen areas that produce smoke or where there is smoke and odors such as in kitchen funnels or in washing facilities. The air stream in the deodorizer passes through a set of filters where particles, grease, soot and odors are removed.

  • SONARtrac - Dredging - Hopper Vessels

    Soil density, hardness, lithology, and sediment particle size distribution can create slurry of variable makeup and density. At a constant pump speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sand outs in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flow meters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements. In addition, the presence of entrained gases may disturb the readings of traditional flowmeters and cause slurry density measurements to be inaccurate.

    Gas analysis & monitoring system for water - natural sciences

    In nature, the chemical elements can be represented by more isotopes, or atoms of the same element, characterized by a different number of neutrons in the nucleus. When the proton / neutron ratio does not exceed that value likely to upset the balance of the atom, resulting in the phenomenon known as stabilization of radioactive decay, the isotope is called stable. That is, over time, will not tend to emit energy and sub-nuclear particles to gain energy stability, giving rise, at the end of the process, the daughter nucleus (a different element, characterized by stability energy).

    Aerosol and particle technology for process control industry

    In order to ensure that an industrial process can be controlled or even improved and optimized continually an analysis of the current situation in real time is necessary. Process data like temperature, pressure but also particle concentration and size distribution of a material flow can supply valuable information and be used for the regulation or the improvement of a process.

    AutoChem - Particle and Droplet Processing

    Optimize Multiphase Processes With In Situ Video and Real-Time Particle and Droplet Measurements. Particles and droplets are everywhere in the chemical, consumer products, pulp and paper, and petroleum industries. Particles grow, agglomerate, break, dissolve, and change shape - all of which can have an impact on process performance and product quality. To be successful, chemists and engineers must understand and optimize particle size distributions to control process efficiency such as stability, separations, or flow properties. In addition, particle and emulsion distributions must be well controlled to ensure repeatable product yield, shelf life, and bulk density.

  • Particulate monitoring for continuous emissions

    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.

  • Independent particle characterization services for environmental industries

    Particle size, particle concentration and other physical characterization analyses are critical to many environmental applications. Regulatory agencies in the environmental sphere demand strict compliance to standards and discharge regulations. Physical testing of samples for parameters such as particle size and concentration can give insight to the process control engineer on how effective and compliant a discharge handling system is operating. Particulate loading from both air emissions and waste water discharge are monitored in many industry sectors and PTL testing provides valuable supporting data in this monitoring process.

    Continuous emissions monitoring in cement kilns

    Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.
