The Hierarchy of Alarms and Operating Envelopes

Traditional operator alarm systems were developed when plants typically operated with a single set of alarm limits. Today’s processes are far more complex, often requiring multiple operating modes, each with its own optimal operating envelope. Yet many facilities still rely on a single set of alarm limits based largely on historical experience.

This webinar introduces the concept of the Process Operating Envelope as a series of nested “Onion” envelopes that define the safe, compliant and optimal operating region of a process. From equipment controllability and environmental constraints to product quality, optimization and production planning, each layer contributes to effective plant operation. The session will also demonstrate how these envelopes can be used to support real-time, multi-mode operation with dynamic alarming.

Attendees will learn how implementing a structured operating envelope approach can improve process control, reduce nuisance alarms, enhance operator effectiveness, support regulatory compliance and improve overall plant performance.

The webinar will conclude with a live Question & Answer session.
