Update on control and safety systems for turbomachinery
All plant workers want to reduce the safety risk associated with turbomachinery operation while avoiding nuisance trips. The goal is to run machines in an efficient manner. In this context, safety ris..
Consider true zero-emission packing for reciprocating compressors
Especially when handling hydrogen, reciprocating compressors must provide ruggedness, operating flexibility and energy efficiency at pressures up to 3,000 psi (200 bar).
Is your plant vulnerable to a brittle fracture?
Much of the process equipment operating today was designed to construction codes that did not require a formal evaluation for low-temperature considerations. Metal temperature highly influences the fr..
HP Reliability: Can integrally geared compressors be successfully used with variable speeds?
A recent HP webinar answered a number of compressor-related questions. This same webinar also generated a few additional ones. A viewer thought that two statements from this presentation were in contr..
Integrated software drives improvement in asset management, productivity
The evolution is all about connecting people, information and devices to give a holistic view of plant operations used to better manage reliability strategy and operational risk.
Access before acceptance: Chip redundancy for SIS
Desired automated plant safety functions are implemented via electrical relays, non-programmable solid-state electronics and programmable electronics (PEs) like microprocessors and microcontrollers. I..
Raise profitability through continuous performance evaluations
Reliability engineers use a wide variety of tools to support plant equipment and to optimize unit uptime and availability. Sound reliability programs assist organizations to be more competitive in the..
HP Engineering Case Histories: Case 81: Is consulting a possible second career for you?
Often, engineers consider becoming consultants as a second career path. This was certainly true for this author, and it occurred early during his career. Equally important, his career turned out well,..
HP Project Management: Case history: Hurdles in dismantling a vintage ammonia plant
Dismantling an ammonia plant is a daunting task under any circumstances. It is even more problematic when the facility is located in a remote place such as central Pakistan and managed by local contra..
HP Reliability: Consider technology-based specialized industrial services
Most downstream professions have heard of (or personally experienced) glitches in activities involving offshoring and outsourcing. Too often, some maintenance and purchasing agents travel the “go..
