    • Abstract:
      Measuring the physical properties of powders and their impact on physical operations is the cornerstone of powder technology. The most common particle properties include density, shape, diameter, particle size distribution as well as surface area. Many unit operations of chemical engineering deal with particles including transport (pneumatic conveying, slurries, dense phase flow, bin flow, and cyclonic flow), flow through packed beds (reactors, absorption columns), and filtration. Intimate mixing of powders in the pharmaceutical industry is necessary to ensure that the active compound is in the right proportions in every pill. Other unit operations include decantation, spray drying, sieving, and crystallization. The diameter of a sphere is a standard geometrical parameter for many correlations to predict performance (pressure drop, terminal velocity). However, seldom are particles spherical and so shape factors/sphericity accounts for the variations in performance rather than a sphere. Sieves, laser diffraction, sedimentation, volume sensors and optical techniques measured particle size. Laser diffraction is the most versatile technique that measures particles between 38 nm and several millimeters.
