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

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

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

Nichols, Lee, Hydrocarbon Processing Staff

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

Sofronas, A., Consulting Engineer

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

Khiani, G. N., GAPV Inc.

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

Hydrocarbon Processing, 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

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.

Hydrocarbon Processing Awards 2020—FINALISTS

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

Causes of reduced or stopped flow in controlled-volume pumps

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.

Solve PRV and piping capacity problems—Part 1

Engineers often uncover problems or inadequacies with pressure relief valve (PRV) and relief system piping capacities that need creative and cost-effective solutions.

Variable capacity control technology facilitates efficient operation for reciprocating compressors

Sanford, J., Siemens

Reciprocating compressors are used extensively in refinery and petrochemical operations to keep feedstocks and products moving through miles of piping.
