Better operator alarms make money for your plant by reducing operational variability, which contributes to a reduction in operating costs and, in cases where throughput is increased, to a reduction in the unit costs of production.

The single biggest cause of poor operator alarm performance is the values at which the alarm limits are set. But search for advice on how to find correct alarm limits and the answer will be “put the limits at the boundary of where you normally operate.” For the practising engineer this advice is next to useless because he or she doesn’t have a way to locate that boundary across many hundreds of variables.

The key is an Operating Envelope or Operating Window spanning the many hundreds or even thousands of variables, some with alarms defined and some without. By modelling process operations as a multi-dimensional geometric object, process and alarm performance and targets can immediately be evaluated and compared, and contradictions or difficulties become immediately visible. The innovative technology which makes all this possible is Geometric Process Control, a unique and powerful tool developed here at PPCL. Watch this webinar from July 2019 to find out more.
