Control Valve Selection for Turbine Bypass Applications
Turbine bypass valves are subject to frequent thermal cycles, high pressure drops, and the need for tight shut off. My article in the May 2023 issue of Power, titled "Turbine Bypass Valve Challenges,” provides methods of inspection to prevent their failure. Surviving...
Control Valve Environmental Packing Improves Performance
Packing selection used to be relatively simple, but more stringent environmental regulations have made it much more challenging. Low-emissions packing solutions provide compliance, along with other benefits, as shown in my article in the June issue of Hydrocarbon Processing, titled Added Benefits of Control-Valve Environmental Packing.
Three Steps to Maximize Your Next Outage with a Data-Driven Valve Maintenance Strategy
Planning for your upcoming planned outage can be aided by this report. If an unanticipated outage occurs, you can review the most recent report to find out which valves might need to be fixed. When planning for the next outage, you will have a priority ranking of valves based on which are the most critical to be serviced. As a result, you can properly prepare for the extent of service and the parts required for the outage. If you are able to complete the planned valve service scope early, you will already know which valves to examine that are second most important to be serviced. Most importantly, you can prevent opening and removing valves that are not in need of maintenance during a planned maintenance event.
Improve LNG Operations with Optimized Joule-Thomson Control Valves
Control valves in liquified natural gas applications must operate reliably under high pressure and cryogenic temperatures to achieve gas separation and liquification. This is especially true for the main cryogenic heat exchanger (MCHE), where the closely-coupled Joule-Thomson (J-T) control valves feeding the MCHE help optimize operation of the most critical area in the entire process.
Better Cybersecurity Increases Confidence to Outsource Data Analysis
Highly secure connections to plant automation systems and intelligent field instruments are enabling Emerson to provide remote monitoring services, helping processing companies and manufacturers to achieve significant operational benefits without having to develop in-house data analysis expertise.
Pressure Relief Valve Continuous Monitoring for Affirmative Defense
Emerson’s Marcio Donnangelo and Marcelo Dultra presented Reducing Data Complexity on Affirmative Defense Claims with PRV Monitoring System at the 2022 4C HSE Conference.
Cutting Control Valve Noise
The modal attenuator consists of a series of carefully engineered resonant cavities to provide sound reduction across a wide spectrum of frequencies. The full-bore design allows unrestricted flow, and internal drain channels drain off condensate which could build up in the device and reduce performance. Installed just downstream of the valve, the modal attenuator achieves an overall sound reduction up to 15 dBa, while creating no restriction in flow capacity whatsoever. The device can be used on existing valves or paired with a low noise control valve to achieve even higher levels of noise reduction. Unlike diffusers or silencers, the modal attenuator works consistently across a wide range of flow rates.
Reduce Fluid Flow Noise Without Pressure Drop
In this 9:51 video, Fisher WhisperTube Product Demo, Emerson’s Shelby Daniels explains in detail how this technology is a passive reactive silencer that reduces system noise across a wide range of conditions without impacting the flow capacity or process.
Reduce Process Noise Without Pressure Drop
The Fisher WhisperTube Modal Attenuator addresses these issues for sound suppression in pipeline and control valve applications. It has a straight-through flow geometry with an inside diameter (ID) that matches the pipe ID and is installed in place of a spool piece. It creates no additional pressure drop.
Duke Energy Addresses Attemperator Issues
Duke Energy’s Heat Recovery Steam Generator Engineer Eugene Eagle and Emerson Automation Solutions’ Director of Steam Conditioning Group Justin Goodwin Power Engineering article, How Duke Energy Addresses Attemperator Issues, describes the deployment of a new steam atomization attemperator design that allowed Duke to reliably and safely run their combined cycle units at very low load conditions.
