CC-SAFETY NET is part of CHEMCAD but it can also be acquired as a stand-alone application.
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.
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.
