particle size monitoring Applications

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.

For more than 25 years Palas has been building systems for the aerosol generation. With more than 30 different systems Palas is market leader worldwide. In particular, the high reproducibility and constancy regarding the particle size distribution and concentration of the Palas aerosol generators have to be emphasized. The Palas aerosol generators are heatable in part up to 150°C. Several types are built in pressure-resistant version and being used successfully worldwide for applications in under and overpressure up to 10 bar.

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.

The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.

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.
