CC-SAFETY NET is part of CHEMCAD
but it can also be acquired as a stand-alone programme.
What can be simulated with CC-SAFETY
NET?
Complex pipe networks with pump, compressor, turbine,
valve, and relief devices based on a CHEMCAD flowsheet.
The simulation of safety and relief valves is carried
out in accordance with DIERS technology. As a result the
mass balance of all streams, their stream direction, physical
properties and physical condition are obtained, with two
phase streams and their regime
being recognised automatically. Several fluid flow models
can be chosen for pressure drop calculations. Performance
data can be entered for pumps, compressors and turbines
allowing the typical performance in plants to be simulated,
e.g. pressure drop and mass flow in an isometric pipe
system.
As CC-SAFETY NET uses the data base and the thermodynamic
models for phase equilibria in CHEMCAD, it is not necessary
to enter physical properties and physical conditions.
Changing the flowsheet or the data can be easily done
allowing the study of various scenarios.
CC-SAFETY NET represents the ideal programme to investigate
complex piping systems and their stream behaviour under
various conditions, e.g. closing of a valve, pressure
change at the entry or exit. All the features of CC-SAFETY
NET are available in CHEMCAD.
The Highlight
CHEMCAD uses Nodes to simulate pipe networks as well as
a special algorithm: simultaneous modular. Here the flowsheet
is treated as a matrix. This enables a quick calculation
and a good convergence of complex processes. User data
can be entered for valves and pipe fittings.
Typical Applications of CC-SAFETY NET
→ pipe networks with pumps and compressors
→ emergency relief and flare networks
→ influence of control valves
Advantages of CC-SAFETY NET
→ pressure drop in complex pipe networks
→ relief device calculations according to DIERS
→ mass and energy balances with component physical
properties
