CHEMCAD represents the basic programme
of the CHEMCAD Suite. CHEMCAD is the tool to simulate
steady state processes. Once CHEMCAD is installed, you
have the capability to acquire add-on programmes.
The flowsheet is created in the user
interface of CHEMCAD, the simulation is performed and
the results are represented. A library of Unit Operations,
which are required to build the flowsheet are provided
on a palette.
What can
be simulated with CHEMCAD?
Gaseous, liquid and solid processes, rectification, gas
washing, absorption and desorption in columns, chemical
reactions, heat exchange of fluids with condensation and
vaporisation, any phase equilibria with diagrams, transport
of gases, liquids, mixed phases in pipes with pump, compressor,
valves for pressure drop calculation, solid grinding and
separation according to particle sizes and electrolyte
reactions.
CHEMCAD is well-known for its easy and clearly structured
user interface. CHEMCAD will lead you to a quick successful
outcome. It will be a pleasure for us to have the opportunity
to demonstrate CHEMCAD to you.
Frequently the unit operations have several symbols with
the same algorithm. The data base consists of more than
2000 components, gases, liquids, solids and electrolytes
with physical properties from e.g. DIPPR and phase data
from e.g. Dechema Data Collection. The engineering units
can be adjusted, e.g. SI. Pipe flow calculations are recognised
automatically by CHEMCAD. Convergency is achieved by special
algorithms. Phase equilibria are calculated with models
such as NRTL and UNIFAC. Equations of state models such
as Soave-Redlich-Kwong are available. A thermodynamic
wizard is available to assist in the selection of the
best models based on the components and pressure and temperature
parameters.
Many extension possibilities are available such as defining
your own components based on the molecular structure,
your own data for the calculation of physical properties
and algorithms for Unit Operations and a powerful interface
to Excel for calculation and reporting purposes.
Typical Applications
→ distillation (rectification)
→ gas washing, absorption and desorption
→ chemical reactions, kinetic and equilibria
→ recycle processes, heat exchange, pressure drop
→ handling of solids
→ neutralisation of acids and alkalis
Advantages of CHEMCAD
→ CAD Flowsheet, easy to use
→ unit operations for gaseous, liquid and solid processes
→ data base with more than 2000 components
(gases, liquids, solids and electrolytes)
→ thermodynamic models for VLE, LLE and SLE |
