Maintenance & Reliability
Safety integrity level verification - A PFD average calculation is not enough
Architectural constraints must also be considered
Do we need relief valves on FCC main fractionators?
Analysis shows that in some cases the system is inherently safe
Operating deflection shape analysis—a powerful tool to increase plant reliability
The technique provides fast and effective root-cause failure analysis of rotating equipment
Consider duplex stainless steels for corrosive exchanger service
Here’s where they have solved corrosion problems
Consider using a new reliability tool: Weibull analysis for production data
Using these techniques, companies can distinguish between processing problems and reliability issues
Case 5: Can we continue to operate the vessel?
Safe operation to a planned shutdown is always preferable
Improving equipment reliability through e-learning
It will change the way people work, learn, communicate and solve problems
HP Reliability: Inductive pumps solve difficult lubrication problems
Authoritative texts show that traditional static oil sumps, both with or without oil rings, represent nonoptimum means of lubricating rolling element bearings. With sump lubrication, the rolling eleme..
Case 4: The wrong bearing in the right place
Calculate B10 life to ensure reliable operation
HP Reliability: Improve turboexpander shaft seals and bearings
Virtually all cryogenic turboexpander seals are either close-fitting labyrinth or noncontacting (dry) gas types. Conventional mechanical seals are not generally used; high velocities prohibit use of c..
