Distillation is a separation process that includes the partial evaporation of a liquid phase and the condensation of the resulting gas phase. The rectification columns are used for the separation of liquid phases. They operate according to the principle of distillation. The substance mix recommended for the operation of the experimental plant is water-ethanol. The separation process of rectification is an energy-efficient distillation process with several stages.

Determination of the tray efficiency of the sieve trays

With different feed levels
Investigation and comparison of a sieve tray column and a packed column

It is used both for quantitative measurements and for demonstrating complex stress states. Photoelasticity is a proven method of analysing and recording mechanical stresses and strains in components. The components used are models made of a transparent, photoelastically sensitive plastic, which becomes optically birefringent under mechanical load.
Features:
Generate stress patterns with linear or circular polarised light
Monochromatic or white light.
Activated Sludge Process enables this process to be demonstrated. A pump delivers raw water contaminated with dissolved organic substances (organic matter) into the aeration tank. Since aerobic microorganisms need oxygen, the raw water is aerated in the aeration tank. The activated sludge is mixed with the raw water by stirring machines. In the secondary clarifier the activated sludge is then separated from the treated water by sedimentation. The activated sludge process is the most important biological process in water treatment. Aerobic microorganisms (activated sludge) in the aeration tank use the organic matter as a source of nutrition, biodegrading it in the process. A portion of the activated sludge is returned to the aeration tank (return sludge). The treated water is collected in a tank. Oxygen concentration, pH-value and temperature can be controlled. The following flow rates are adjustable: raw water, return sludge, internal recirculation for pre-denitrification and air.

The flow properties of a powder or bulk solid determine how it behaves during handling. A motor moves the shear cell relative to the lid in order to apply shear to the sample. For compaction (pre-shearing) the sample is subjected to a large normal force. In a ring shear tester, a bulk sample is contained in a ring-shaped shear cell. A normal force is exerted on the sample by way of a lid. A hanger from which a variable weight is suspended generates this normal force. For example, material may flow irregularly out of silos, or the flow of bulk solid may come to a stop. In order to avoid these problems in practice, soils can be designed on the basis of measurements using shear testers, such as the Jenike shear tester or a ring shear tester. From the shear force characteristics, properties such as the compressive strength and internal friction of the bulk solid can be determined. An electronically amplified force transducer measures the shear forces which are then recorded by data acquisition software over time. To determine the density of the bulk solid, the volume of the bulk sample is ascertained by recording the lowering of the lid using a vernier caliper gauge. After pre-shearing, shearing to failure is executed with a reduced normal force (strength measurement) and likewise recorded by the software.

The mixed vapour contains a higher concentration of the component with the lower boiling point (ethanol). It leaves the top of the column and is condensed using a condenser and a phase separation tank. Distillation is used to separate liquid mixtures made up of individual liquids that are soluble in one another. Rectification refers to distillation in a counterflow. Part of this condensate is collected in a tank as product while the rest is fed back into the column. The mixed vapour produced then moves upwards in the column. Here, on its way downwards, it undergoes further heating and material exchange with the rising mixed vapour. Ethanol/water is recommended as the liquid mixture for the. It is fed into the column. It partially evaporates on its way to the bottom of the column where it is heated to boiling. The liquid phase moves to the bottom and can be collected in two tanks. This exchange causes the vapour phase to become richer in ethanol and the liquid phase to become richer in water.
....
Absorption is used to remove one or more gaseous components from a gas flow using a solvent. The flow rates of the gas components are displayed. A compressor delivers the gas mixture into the lower section of the absorption column. First of all, a CO2 and air gas mixture is produced. Water is used as the solvent. The CO2 is absorbed by the downward flowing water. As the pressure is reduced and the temperature is increased, the solubility of the CO2 falls. A heater heats the water. A water jet pump generates the vacuum in the desorption column and causes the CO2 gas to be emitted from the water. To separate the absorbed CO2, the charged water is then fed from the lower section of the absorption column into a desorption column. It is possible to adjust the mixing ratio using valves. A pump then delivers the regenerated solvent back into the absorption column. The water temperature can be controlled. Flow rate, temperature and pressure are continuously measured. In the column, part of the CO2 is separated in the counterflow with the solvent.
