The programme CC-BATCH can be
acquired as a stand-alone version or as an add-on version.
The batch distillation process is chosen in applications
involving small volumes of complex multi component mixtures.
The batch distillation process has some advantages as
compared with a continuous rectification but experience
is required to achieve an optimum solution. CC-Batch helps
the user to reach this objective quickly.
What can be simulated with CC-BATCH?
CC-BATCH allows a batch distillation, comprising a multi
component mixture, to be simulated into fractions. Numerous
specifications of fractions are possible enabling the
user to simulate close to real conditions. The simulation
can determine the optimum conditions for practical use
in a short time Conditions can be chosen for each fraction
individually, e.g. with respect to time, composition in
the distillate, in the product or in the still. During
the course of the simulation the amount and concentration
flow in the distillate, in the fractions and in the still,
as well as the thermal requirements, can be reported graphically.
The calculation is so fast that several recalculations,
using different parameters, can be done in order to achieve
better results. Thus change over fractions can be minimised,
mole fractions maximised and finally the thermal efficiency
and timings of the batch distillation can be optimised.
This leads to the fact that the optimum solution can be
obtained very quickly. CC-BATCH provides many advantages
as compared with alternative empirical methods.
It goes without saying that constant and variable reflux
ratio operation can be simulated. In the latter case the
reflux ratio starts with a low value and increases exponentially.
Thus the optimum operating conditions in regards to thermal
energy can easily be determined using CC-BATCH.
The fractions are collected in a vessel thus allowing
further studyin a steady state simulation.
CC-BATCH offers a great variety of features. Do not hesitate
to test it.
Typical Applications of CC-BATCH
→ separation of a multi component mixture
→ specification of a column up to 200 trays
→ formation of fractions
→ variable specification of fractions
→ constant or variable reflux ratio operating mode
→ further treatment of products in CHEMCAD
→ 2-phase condensation
Advantages of CC-BATCH
→ very fast simulation
→ graphical presentation of the results
→ easy to optimise processes
