Control fouling on preheat trains with a two-stage approach
Fouling in heat exchanger preheat trains is a well-known problem in the refining industry.
Reliability: Interpreting API Standard 618 for reciprocating compressors
A rotating machinery engineer working for an engineering, procurement and construction (EPC) contractor in India is often involved in selecting reciprocating compressors for hydrocarbon processing plants.
Engineering Case Histories: Case 88: Normal operating loads do not usually cause failures
Equipment of all types are designed for normal operating conditions, usually with some margin for unknowns.
HP Innovations
The FM-approved FireChek thermal shutoff valve with resettable memory shape alloy can now be used to automatically shut down a pneumatic control system when a nearby fire occurs, or when the ambient temperature reaches 135°F, 150°F or 165°F.
Use dynamic simulation to increase reliability of hydrogen generation
