The range of operating conditions within which equipment or processes are designed to operate safely, reliably and efficiently.
An Operating Envelope defines the acceptable range of operating parameters, such as pressure, temperature, flow, composition and load, within which equipment or processes are intended to operate safely, reliably and efficiently. Operating outside the defined envelope may increase risk, accelerate degradation or require corrective action.
Operating Envelopes establish the safe operating region for equipment and process systems.
Operating Envelopes are established during design and refined through operating experience, process safety studies and equipment performance assessments to support safe and reliable operation.
An Operating Envelope defines the complete safe operating region, whereas an Operating Limit specifies an individual boundary that should not be exceeded.
