In a Hydrocarbon Processing magazine, Control Valves for Carbon Sequestration Applications, Joe DeMonte and Suzanna Grills share how control valve selection for these projects can be challenging, but achievable with the right level of support.
Greg McMillan wins best paper/presentation in his category for his Control Valve Modeling and Control entry. Here are 33 best practices that Greg shares from the paper.
In a Fugitive Emissions Journal article, ESG Improvements Through Emissions Reduction: Issues and Opportunities, Emerson’s Bruce Ofori shares how new technology adoptions, and reviewing outdated practices and equipment retrofits, can build stakeholder confidence with respect to the reporting of greenhouse gases (GHG) emissions, volatile organic compounds (VOC), and hazardous air pollutants.
For air-operated control valves, the pneumatic power at a constant supply pressure is proportional to the mass flow rate of instrument air. The pneumatic/eletro-pneumatic/microprocessor-based digital valve controller is used on most control valves operated in closed-loop control, where the input signal is continuously changing.
March 12-16, is a face-to-face meeting in Houston, Texas, the 2023 Spring Meeting and 19th Global Congress on Process Safety. Some of the Emerson presenters and topics include: Jacob Tardoni—Mapping an Evacuation in Real-Time: Digital Mustering with Wireless Personnel Location Technology; Greg McMillan—Best Practices in Column Control Distilled, and Control Valve Response Modeling and Control.
In a Hydrocarbon Engineering article, Control Valve Selection for Ethylene Plants, Matthew Wagner describes how to choose the right combination of valve style, trim type, materials of construction, and digital positioners for critical valve application in an ethylene unit.
The adoption of hydrogen as a green energy resource has been developing for decades, and it is now accelerating as the stage has been set for the gas to play a prime role to meet the world’s environmental, social, and governance goals.
The Cool Parts Show’s episode, 3D Printed Valve Part Helps Prevent Cavitation, explains cavitation and its damaging effects on the surrounding process, how the Fisher Cavitrol Hex Trim helps mitigate cavitation, and the additive manufacturing process to create this ball valve component.
In a Hydrocarbon Processing article, “Simplifying Safety Valve Installation and Maintenance”, Kurtis Jensen & Lura Parrent highlight new technologies on how to simplify safety valve installations while improving performance and reliability.
The TESCOM AGI Double Block Bleed (DBB) and Hand Valves enable fueling station operators to maintain a safe working environment during instrumental maintenance routines. These maintenance-free valves feature a positive double-block arrangement that protects workers after they isolate process pressures, while their modular design reduces the number of potential leakage points.
In a Power magazine article, “In-Service Testing of Pressure Relief Valves”, June DelGrosso highlights equipment that can perform accurate testing of relief valve setpoints without taking them out of operation.
This 3:17 video, Maintaining the Fisher 627BM Direct-Operated Pressure Regulator, guides viewers through the procedures required to maintain the new Fisher 627BM pressure regulator.
