In an Oilfield Technology article, Switching on to Electric Control Valves’ Potential (pp. 54-59), Emerson’s Scott Losing and Andrew Prusha describe how electric valve actuators have advanced to replace pneumatic actuators driven by natural gas.
In a Hydrocarbon Engineering article, Improving safety shutdown valve reliability, Emerson’s Stanley Amirthasamy and Lura Parrent share ways to improve the reliability of final elements when they are safety valves. They open noting how safety valves are used to bring a process to a safe state.
In a Plant Engineering article, Advanced valve diagnostics drive savings, Jordan Mandernach and Emerson’s Brent Baker teamed up to share these diagnostics in digital valve positioners can help drive safety, reliability and efficiency improvements in the process.
In a Hydrocarbon Engineering article, Sound Suppression, Emerson’s Bill Flowers shares ways to reduce high noise conditions caused by control valves and surrounding piping.
Three new short, YouTube videos are part of the Control Valves Basics playlist which also has quite a number of other videos to quickly ramp you up the learning curve on basic knowledge of control valves.
With the hydrogen demand growing globally, some challenges are arising across the supply chain to move it from production to consumption. One opportunity is blending a percentage hydrogen into the existing pipeline infrastructure. Rossella Mimmi and Attilio Lepore address the challenges of blending hydrogen into the existing pipelines such as leakage and embrittlement.
The DVC6200 HW2 digital valve controller provides a unique feature to detect position feedback issues and automatically revert from travel control to pressure control (I/P transducer mode) to keep the valve operational. This can help avoid costly unplanned spurious trips that can affect plant operation.
Emerson’s Katherine Bartels and Adam Harmon address the subject of control valve choked flow in liquid and gas applications in an International Society of Automation Intech article, Choked Flow in Control Valves.
In a post, Valve Travel Control-Pressure Fallback, Emerson’s Riyaz Ali shared the process of how a control valve with a digital valve controller could fall back to standard pressure control upon an issue with the travel sensing mechanism.
A Digital Valve Controller, the DVC6200 (HART or Foundation Fieldbus) can detect position feedback problems and automatically revert to I/P [current to pressure] transducer mode to keep the valve operational. This avoids costly unplanned spurious trips, which are critical for plant operational performance.
In this very first episode of the EVALUE8 Podcast Series, we interview Karthik Dayalan, an expert and the Parts Business Development Manager in Emerson. Having met several customers, we discuss and explain the risk of using non-OEM parts and the benefits of using OEM Parts to operate your plant safely.
When the plant is not running the way it should, with excessive variability, alarm conditions or sub-optimized performance, plant engineers often connect with the Emerson Production Performance consultants. I had the opportunity to sit down and record a podcast with Emerson’s James Beall who is a member of the team.
