Notes:
Product quality is influenced by the properties of feedstocks and by production parameters. In contrast to gases and liquids, the quality of solids is also affected by the particle properties, such as size, specific surface area, structure and shape. These are the properties which are primarily changed in solids process engineering.The accuracy and cost of possible methods for the measurement of the particle properties of feedstocks, intermediates and end products are discussed. Examples of the methods discussed are laser diffraction spectrometry, quantitative image analysis and photon correlation spectroscopy.The measuring techniques required for monitoring production processes in solids process engineering are illustrated by simple examples. In the field of process control in particular, there is still room for improvement, since there is a lack of suitable sensors and models. Process monitoring is necessary in order to ensure that product quality meets requirements which are constantly increasing.
