Analysis of alarm management in startups and shutdowns for oil refining processes

This article presents an analysis of startup and shut down operation on plants of oil refining processes which generates a significant amount of alarms that need to be analyzed in order to avoid abnormal situations. The first part will analyze existing standards ANSI/ISA/EEMUA identifying the most relevant aspects and then we will do a study of the interpretation of these standards in real situations in processes of startup and shutdown procedures. Culminating with a study about the mathematical model of the algorithm, and the use of these tests for detecting possible failures early using State Machine as the model base.
