TECHNOLOGY CORNER
Modeling at Detailed
Engineering Stage
Through this phase, special attention
is paid to the detailed engineering of
the possible technical solutions.
Depending on their nature, the models
can either provide a description
of how the system behaves in certain
conditions or be used to calculate the
detailed geometric measures of the
equipment.
For example, all the dimensions of
a distillation column can be calculated
when we definitively establish
the separation requirements.
It is useful to have detailed documentation
concerning all the
assumptions and theories used in
the model. The yield and energy
consumption of a process are easily
optimized using fine-tuned models
to design a new unit or process. Depending
on the process integration,
pinch analysis and other similar
analysis procedures can be used to
find a solution of heat integration.
Various data on streams and energy
consumption, which are easily developed
from simulation results, can be
used to sustain the adopted technical
solutions.
In the detailed
engineering stage,
models are used
for the purpose for
which they have been
created: the design
and development of a
full scale plant which
is described in the
detailed engineering
stage.
