Steam Purge Valve Failure during Drum Switching OperationIn October 2019, the inlet transfer line isolation valve (SP-6A) at ENAP Refinery in Chile does not open during drum switch operation. The operations team bypassed the unit in order to inspect the valve and the actuator. A break in the worm gear of the gearbox is discovered and is replaced but still, it was not possible to open the valve electrically or manually. In this presentation, we will share the steps taken to bring the valve back to operations. Also, Velan will present the guidelines to prevent this type of incident.
