Reliability and maintenance: The path to world-class performance
HPI companies in a progressive culture strive for failure-free operations with defect elimination and uninterrupted operation.
HP Reliability: Upgrade the design of vertical, multistage centrifugal pumps in low-temperature services
The overall mechanical design of most API-style vertical-column pumps (Fig. 1) comes close to meeting the expectations of modern pump users. Such pumps are often equipped with self oil-lubricated bear..
HP Reliability: Closed-oil-mist systems and maintenance cost avoidance
A recent Hydrocarbon Processing (HP) article conveyed an industry finding that dates back several decades: Oil mist successfully lubricates operating machinery, protects and preserves standby equipmen..
HP Integration Strategies: The energy water nexus
Whether or not you subscribe to the global warming and “peak oil” arguments, it is clear to almost everyone in the industrial world that “business as usual” is not sustainable inde..
HP Engineering Case Histories: Case 71: Statistical visual data can be useful in troubleshooting—Part 1
I’ve spent many years troubleshooting equipment, along with investigative research. In research-statistical design, data analysis is frequently used when test information is available. This artic..
Tyco signs global agreement with Shell to provide pressure relief valves
The five-year agreement covers Crosby and Anderson Greenwood direct acting and pilot-operated pressure relief valves, line block relief valves and supporting services for all of Shell's global operations. During 2011, Tyco was also selected by Shell to provide butterfly valves in a similar arrangement.
HP Engineering Case Histories: Case 70: Twenty rules for troubleshooting
In previous Engineering Case History columns, I have discussed checklists and their value in avoiding errors during startups. While the rules cannot replace common sense or a logical and methodical ap..
Modernize your compressor lube- and seal-oil systems
Each pipe or control line should be traced to its origin, the design intent must be well understood, and all owner-purchaser questions answered by the vendor-manufacturer.
Consider new developments for variable-speed electric motors
New challenges, recent developments, the latest mechanical issues and main reliability factors for large variable-speed electric motor drivers in HPI plants are presented here.
HP Reliability: Consider best-of-class lubrication practices
Last month’s column explained that all hydrocarbon processing (HP) facilities use machinery, and these machines require lubrication. Periodically auditing one’s lubrication practices is part..
