Model for Process Control Engineering - General
The model for process control
engineering, a laboratory distillation
plant, promotes the understanding of
the functioning of sequential control
systems by developing and
programming simple sequential control
systems.
So, when creating a sequential control
for example – regardless whether in
the laboratory (automation of
experimental or test processes) or in
production (automation of production
processes) – reaction processes are
split up into very small successive
steps. This way the student learns to
think in those single steps the control
unit is using.

Plant Description
This model in lab size is meant to
represent the batch distillation
principle, which is one of the most
frequently used dissociation
methods of distillation in process
engineering. The control and
switching processes using
temperature, clock cycle and level
monitoring, which are important in
large and small plants, are
combined with a programmable
logic control on an operation and
automation level and are controlled
and activated in logical order.

The subsequent control board level
with PC visualization, open-loop and
closed-loop control including
documentation is supposed to
explain the application of instrument
boards as practiced in industry.
The laboratory distillation plant is
made from a chemically resistant
special glass (borosilicate glass 3.3)
in order to offer a full view and to
make it possible to observe the
experimental process in detail.
The 2-l distillation flask with external
heating represents the often used
distillation vessel out of steel,
steel/enamel or special alloys.
Sensors for temperature and level
monitoring are brought in via the
various nozzles.
