Maintenance & Reliability
Troubleshooting repetitive failure of a CO2 ompressor rotor
Here's how the plant personnel overcame the unique and complex problem of residual magnetism
HP Reliability: Consider bidirectional flow devices for mechanical seals
Many dual mechanical seals found in centrifugal pumps use either pumping rings or pumping screws to move barrier fluid. Typical flowrates achieved with pumping rings are extremely low, with most of th..
Case 30: One cause of a pump not pumping
A stronger pump can block out the weaker one
Update design and maintenance methods for refractory systems
Better design methods and repair efforts reduce failure of these systems
Improve asset performance management
This methanol plant implemented a system that supported its strategic objectives of managing risk and improving profitability
HP Reliability: Don't just repair: Upgrade!
 Fig. 1     Bearing mounting options. A well-known trade journal recently published a page on thrust-bearing orientation..
HP Reliability: Filtration and beta ratios
Effective filtration of lubrication and hydraulic systems is of real importance to the reliability professional. The general idea is to allow no particles larger than the clearances in system componen..
Effect of process deposits on the corrosion behavior of titanium in brine
The temperature and pH need to be controlled to avoid problems
Case 29: Pressure buildup in a 'blocked-in' pipe
Liquid thermal expansion can rupture pipes
Consider an advanced method of steam trap condition monitoring
