Implementation of predictive maintenance strategy

Vibration measurement and visual inspection, ultrasonic inspection, ESA (Electric Signature Analysis) and MCA (Motor Circuit Analysis) are performed as routine tasks in the plant. Ultrasonic inspection is used for machines with slow speeds, as a complement to vibration measurement, and electrical measurement techniques are used on the most critical motors. ESA tests are performed with the motor energized and MCA tests with the motor de-energized.

Another fundamental service is the detection of hexane leaks, a flammable and explosive compound that is the main production consumption in order to extract the oil. With the correct application and combination of predictive techniques, we achieve a reliable diagnosis and an improvement in the monitoring of KPIs. We anticipate failures in order to plan corrective works at the next shutdown, which results in fewer unplanned shutdowns, lower cost and duration of repairs. Thus, we have a holistic view of the mechanical and electrical condition of the equipment, generating a history of asset behavior and being able to cross-reference data between similar machines to make decisions based on continuously updated real data.
