Valves

High-frequency acoustic excitation—Part 1

Process Consultant: Datta, A. K.

Failure of a piping section at the outlet of pressure safety valves (PSVs) and control valves—where significant differential pressure exists (particularly in gas processing industries)—is a common problem in industries.

Stress qualifications for standard and nonstandard valves in piping systems

Various types of valves are used in refineries, petrochemical plants, fertilizer plants and utilities.

Advances in compressor anti-surge valve design enhance reliability and performance

Flowserve Corp.: Haines, B.  |  Nelson, M. P.

Centrifugal and axial compressors are some of the most critical components used within a process plant to handle gases.

Editorial Comment: Optimizing operations by advancing process controls, instrumentation and automation technologies

Hydrocarbon Processing Staff: Nichols, Lee

When driving by or visiting a refinery or petrochemical plant, one cannot help but gaze at the expansive sea of metal towers.

Engineering Case Histories: Case 110: A checklist for vibration analysis

Consulting Engineer: Sofronas, A.

Periodically, I receive questions from engineers around the world on why a piece of critical machinery is vibrating excessively.

Mitigate transient/hydraulic surge in liquid pipelines with nozzle check valves

GAPV Inc.: Khiani, G. N.

Liquid pipelines often come across hydraulic transients, which can damage pipelines and associated equipment (i.e., pumps, valves, stations, etc.).

Hydrocarbon Processing 2020 Awards WINNERS

<i>Hydrocarbon Processing</i>, the downstream processing sector’s leading technical publication, has announced the winners for its third annual awards.

How valve upgrades can improve tank and terminal facility operations

Emerson: Leavitt, D.  |  Arroyo, M.

Tank and terminal facility profitability ultimately rests on a handful of key performance indicators (KPIs). The ability to maximize tank capacity utilization—while minimizing the time it takes to load and unload ships, trucks and rail cars—drives the bottom line. All those transfers must happen quickly and accurately, while avoiding product contamination.

This special section details all finalists within each category for the fourth annual <ital>HP</ital> Awards. The winners will be announced on Oct. 1.

Causes of reduced or stopped flow in controlled-volume pumps

Saudi Aramco: Badughaish , M.  |  Al-Dhafiri, A.

Controlled-volume (CV) pumps, also known as metering or dosing pumps, are designed to deliver a small quantity of fluid at a precise rate with relatively high pressure.
