Valves
Aging pressure relief valves: Are you managing history well?
The risks associated with the malfunction or blockage of pressure safety valves (PSVs) are significant, and operating facilities invest heavily in preventive maintenance (PM) programs to mitigate the risks and ensure that PSVs are functioning exactly as per design requirements.
Safety and environmental benefits of reliability engineering
When you boil down the mission of reliability to its bare essence, the job is to deliver maximum operational availability for the least amount of money over the lifecycle of the asset.
Reliability: Houston: We have another problem
The state of understanding science and facts on one side and distinguishing these from anecdotes and far-fetched opinions on the other side, should be concerning to us.
Control valve design challenges for green diesel processes
Green (or renewable) diesel is a biofuel that offers several advantages over biodiesel, so many refineries are increasingly including it in their production portfolios.
Assessment of independent protection layers in an LOPA study—Part 1
Industrial facilities, especially those operating in the chemical, oil and gas and petroleum industries, contain inherent risks in operations due to the processing of materials that are hazardous in nature.
Hydrocarbon Processing 2021 Awards FINALISTS
<i>Hydrocarbon Processing</I>, the downstream processing sector’s leading technical publication for nearly 100 yr, has announced the finalists for its fifth annual <i>HP</i> Awards, which celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.
Valves: Protect safety valves using rupture discs
For many years, emissions were an unavoidable consequence of industrial development.
Redundant control pilot valve system adds reliability in downstream operation
In downstream processing facilities, such as refineries and chemical plants, downtime is a significant source of lost revenue.
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.
