HIPPS (High Integrity Pressure Protection System) overview

HIPPS offers the highest level of processprotection:

• Plant’s Distributed Control System (DCS)

• Process Shut-Down (PSD)

• Emergency Shut-Down (ESD)

• High Integrity Pressure Protection System (HIPPS)

Critical safety system protecting against overpressurisation

Safe shut-down hierarchy

DCS

Systems and components require Safety Integrity Level (SIL) rating

HIPPS drivers

• Safety regulation

• Environmental protection

– Reduced venting & combustion of gases

• Traditional overpressure methods ineffective or expensive

• Independent, high integrity solution requirement

• Risk of catastrophic failures

Our HIPPS capability

IMI Severe Service has responded to this demand:

• Custom-engineered HIPPS solutions

• Actuator and valve solutions

– Enhanced by Truflo acquisition

• Logic solver hardware and software

• Diagnostics and testing

Cost of failure significantly exceeds the cost of the solution

What is desuperheating?

• When steam is heated past saturation, it is “superheated”

• Condensers and boilers cannot take Superheated Bypass Steam (SBS)

• Water is used to cool SBS before entering the boiler or condenser

• If not done correctly, extremely high cost of failure

Why is desuperheating critical?

• Water slug damage

• Pipes knocked off supports

• Ruptured dump devices, severe valve damage

• Thermal fatigue / cracking of pipes

• Cracked valve bodies, desuperheaters and valve trim

If the process in not done properly, it can cause major damage to the plant, such as:

Science behind desuperheating

• Water droplet size is key to superior desuperheating

• Low-end control determines component life

• Temperature control improves component life

In summary

• Innovation focus

• Severe Service– tackling the most difficult applications

• Customer and market led

• World leading valve engineers– Valve Doctors

• Excellent execution
