Test rigs: stirred tank (discount./account.), Stirred tank cascade, fluidized-bed granulator, reverse osmosis, rectification column, extraction column, absorption plant

• Internship Technical Chemistry: Currently the tests are offered fluidized bed granulation, agitated boiler cascade and agitator reactor

• Fluid bed granulation: In a fluidized bed reactor, sugar is coated with cocoa as a model process, e.g. for catalyst production on an inert carrier.

• Stir-fry boiler cascade: With five consecutively connected continuous stirring reactors, dwell time-sum curves and spectra are measured.

• Stirring reactor: Using the example of the saponification of ethyl acetate, a reaction kinetics 2nd order is investigated. Two discontinuous tests at different temperatures determine the reaction velocity constants and activation energy. A continuous trial determines sales.

• Practical Work thermal process technology: Currently, the tests are offered rectification and extraction.

• Rectification: With a rectification column (bell bottom and filler column combined) concentration distributions are determined at different return ratios. From this, the theoretical soil number and the soil efficiency are determined.

• Extraction column: The distribution of a transition component to two almost non-mixable phases is determined with a continuous extraction column. Depending on the stirring speed (disc stirrer) and the volume flows, the theoretical soil number and the soil efficiency are determined.
