Braskem, a Brazilian petrochemical company and a leading producer of thermoplastic resins, has moved toward predictive maintenance and identify the assets that need special attention, to regain its degrading performance. Braskem's asset management system architecture include real-time information from HART and FOUNDATION fieldbus devices sending diagnostic information into the distributed control system and the maintenance shop. The Enhanced Device Description Language and Field Device Tool/Device Type are used to create a friendly interface. The company performed a valve travel calibration through AMS Suite and its AMS ValveLink SNAP-ON application after it discovered a problem with one pressure control valve on a propylene storage tank that had to remain 100% closed under normal conditions. Braskem, using the diagnostic capabilities of AMS Suite and a CSI online vibration monitor, identified excessive vibration in an axial pump on a loop reactor.
