Class IntegratedSafetySystemExample

java.lang.Object

neqsim.process.util.example.IntegratedSafetySystemExample

public class IntegratedSafetySystemExample
extends Object

Comprehensive example demonstrating integrated safety systems including:

• Emergency Shutdown (ESD) System with SIL-2 implementation
• High Integrity Pressure Protection System (HIPPS) with SIL-3
• Pressure Safety Valve (PSV) as final protection layer
• Blowdown system with flow control
• Flare system with heat radiation monitoring
• Multiple pressure and temperature transmitters
• Fire detection system
• Various process scenarios (normal, overpressure, fire, HIPPS activation)

Safety Integrity Levels (SIL):

• SIL-3: HIPPS (PFD 0.0001-0.001) - High pressure protection
• SIL-2: ESD (PFD 0.001-0.01) - Emergency shutdown
• SIL-1: Alarms (PFD 0.01-0.1) - Operator intervention
• PSV: Mechanical final protection layer
