Practical training for Process Engineering

Our group conducts Practical Training for Process Technology for selected tasks related to processing dispersed systems.  Other parts of this course are supervised by our colleagues from thermal and chemical process engineering. The course schedule is announced at the beginning of each semester; notes for preparation are provided via OPAL heruntergeladen ( Praktikumsunterlagen 5. und 6. Semester).
Please read the Hints for preparing the measurement reports (in German).

Our Research Group is responsibel for the following topics:

Granulometry

Granulometry means measurement of particles. The training occurs in our laboratory, the Centre of Particle Technolgy particle (Georg-Schumann-Bau A119-121). Students employ different analytical techniques - e.g. mikroscopy, sieving and sedimentation - in order to determine the particle size distribution of reference materials and real-world materials. The variation among the obtained granulmetric results are discussed.

Fluidised Bed

The practical training with a fluidised bed is located in Merkel-Bau. The training comprises the fluididation of a bed of polymer pellets by an upwart air flow from beginning fluidisation until the complete exhaust of all particles. By continuous monitoring of relevant process quantities, students can distinguish the various stages of fluidisation and derive characteristic parameters of the fluidised bed. The experimental findings are compared with theoretical predictions.

Standard stirring device

The training on the standard stirring device takes place in Merkel-Bau. Experiments aim at the determination of the characteristic power curve, i.e. Newton-number vs. re-number, for different stirrer geometries and stirring configurations. In addition, the mixing time has to be determined. Students learn to work with dimensionless numbers for describing process performance and get a slight impression on challenges in stirring practice.

Filtration

Training on filtration takes place in Merkel-Bau. It comprises experiments for solid-liquid separation by means of a rotary vacuum drum filter and a laboratory test filter. The experimental results serve for the determination of the flow resistance of the filter cloth (synthetic textile), the specific cake resistance (kieselguhr) and the suspension number.
