To summarize, mechanical equipment such as shutdown valves, control valves, actuators, and accessories such as positioners are designed keeping in mind a plant’s life of around 25 years. Though you may not find any written or stated document from any supplier or manufacturers since mechanical deterioration depends on many parameters like internal process-related conditions or external environmental conditions, operating media (air, hydraulic fluid, etc.), proper care exercised during application selection & sizing, and more.
In a Flow Control article, Understanding and solving control valve cavitation problems, Emerson’s Thirumalai Karthik (TK) Arasu opens highlighting the potential severity of cavitation.
Michelle Schulze shares how upstream oil and gas production sites must comply with limits on VOC emissions, and this effort is a good time to examine all the related equipment.
In a LinkedIn essay, Transform to Valve 4.0: Digital Control + Analytics, Emerson’s Jonas Berge describes how the performance of control valves can be more effectively managed and maintained for better operational performance.
In a Hydrocarbon Engineering article, Disparate Data (registration required), Emerson’s Jodi Johnson describes how this shift helps create value for manufacturers and producers. She opens noting the challenges inherent in the paper & pencil practice.
In a Pumps&Systems article, Digitalization to Predict Reliability of Mechanical Valves, Emerson’s Riyaz Ali shares ways continuous monitoring technology can help.
The Fisher Control Valve Handbook is the best place to begin to better understand sizing and selection of control valves for your application.
In a Processing article, Monitoring pressure relief valves as part of a digital ecosystem reduces cost and improves performance, Emerson’s Marcio Donnangelo and Marcelo Dultra describe how continuous monitoring “can identify when pressure incidents happen while monitoring valve conditions to simplify maintenance programs.”
In a Hydrocarbon Processing article, Using ball valves in high-temperature applications, Emerson’s Jason Jablonski and Wade Helfer share recommendations for manufacturers and producers to use in specifying and purchasing suitable valves.
A University of Arizona publication, A Brief History of RFID, traces the history of radio-frequency identification technology back to a Russian physicist in the 1940s and commercial applications began to appear in the 1960s. By the 1980s and 1990s the technology...
An ethylene plant has a number of very large, very critical compressors which will cause the entire plant to shutdown if they ever trip. The cracked gas compressor increases the entire cold-side feed from around 3 psig to ~475 psig, typically through 5 stages. The two refrigeration compressors are the next biggest compressors that can also shut down the entire plant if they trip.
An Asian refiner sought to improve reliable operations around their control valves a decade ago. I caught up with Emerson's Sumitaka Ichiki who shared the story of their journey to more reliable operations. Using the Fisher FlowScanner valve diagnostic software, they...
