Valves
Air-to-air pneumatic booster fail-safe system for valves
In pneumatic valve automation systems, it is common to hear the following terms for valve positions: “fail open (FO),” “fail close (FC)” and “fail last (FL)”.
PSV sizing: An alternative solution to the homogeneous direct-integration method
Pressure safety valves (PSVs) are designed to protect personnel and plant properties from an overpressure occurrence in equipment or piping by relieving fluid to a safe location.
Keeping fugitive emissions costs down with low-E valves
Fugitive emissions have become an increasingly critical area of interest for chemical processing and refining facilities.
Case study: Reliability of low-flow, high-head pumps
Pumps are one of the key elements used in different industries, including oil and gas, petrochemicals and water treatment.
Online treatment of a slide valve fault in an FCCU
The regeneration slide valve is a key piece of equipment that controls the ratio of catalyst to oil and reaction temperature in FCC units (FCCUs).
Debottleneck analysis on a coker debutanizer via simulation models
Production requirements for more valuable refined products and/or increased refining flexibility are increasing due to new regulations.
Key instrumentation technologies to tackle the toughest measurement challenges
Just as some people seek out extreme sports, process manufacturing has its extreme applications, and engineers who design for these environments must find ways to safely contain and monitor all manner of dangerous reactions and products.
