What is ESD?
An emergency shutdown system or ESD system is a highly reliable control system for providing a safety layer during emergency situations. It helps to prevent situations from having catastrophic impacts economically, environmentally, or operationally. Emergency Shutdown Systems in any plant minimizes injury to working personnel & the environment or damage to equipment, by protecting against leaks, hydrocarbon escape, fire outbreaks, explosions, etc. The application of emergency shutdown systems has been substantiated in the oilfields (oil well heads), Nuclear plants, oil and gas processing plants, steam and gas turbine power plants, chemical & petrochemical plants, boilers, geothermal industries, etc. During an emergency situation, the process operations are stopped by the ESD system, therefore, isolating the hazard to escalate.
Functions of an Emergency Shutdown System
All emergency shutdown systems should always work at the back-end throughout the plant operation as it is one of the main security systems. The major functions of an emergency shutdown system are:
- Shut down of the system or equipment during a critical situation
- Isolate electrical equipment
- Proper control of ventilation during an emergency
- Stop or isolate hydrocarbon sources from potential hazard situations
- Blowdown and depressurization
- Prevent dangerous event escalation like prevention of ignition and explosion
- To protect personnel, asset, and the environment
Note that critical situations may be triggered in any plant by various factors but emergency shutdown systems should be able to handle those in an effective manner.
