Maintenance & Reliability
HP Reliability: Consider disc pumps where impeller pumps fail
Until recently, finding a suitable pump was difficult for plants pumping viscous fluids or fluids that undergo viscosity change. Here, using conventional centrifugal pumps may lead to poor performance..
HP Reliability: Strategic mechanical seal partnerships
Not all mechanical seal supplier agreements benefit both parties equally. We have recently seen some rather one-sided ones. At a recent users conference, the suggestion that the "partner" should discl..
All you need to know about centrifugal pumps, Part 2
Specific applications, condition monitoring and other considerations are detailed
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
