Abstract
The present article shows the integration of techniques for the early fault detection and diagnosis in industrial processes, in order to make recommendations to the operations staff in an industrial process and avoid safety incidents. The early fault detection and diagnosis provides assistance to the operations team in an industrial plant in order to make the right decisions during the process. This prevents small faults from escalating to critical situations where risks such as loss of human lives, damages to the environment or economic loss may exist. The article presents a prototype in a fluidized catalytic cracking unit
