Using Sustainable Initiatives to Achieve Decarbonization Goal
Sustainability and decarbonization have become an integral part of the discussions around energy security and long-term sustainable economic growth.
Emerson’s Fisher control valves and instruments play a role in helping you achieve your sustainability goals.
An Alternative Solution to Bellows Failure with Balanced Diaphragm Technology
This article discusses a recently introduced PRV design that replaces bellows with a balanced diaphragm. This new balancing technology can be installed as an upgrade to standard bellows PRVs, and it extends backpressure limits while providing greater flow capacity than a similarly sized balanced bellows PRV.
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...
Designing & Specifying Process Automation Parameters to Drive Performance
A plant’s performance can be optimized at the intersection of capital equipment, production processes, and people. Done correctly from the start through the selection of technologies and how they are deployed can lead to higher levels of productivity, reliability, safety, and sustainability.
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.
Accelerating Hydrogen Infrastructure: Key Insights in Our Whitepaper
Hydrogen-fueled vehicles are on the rise, necessitating the development of reliable and efficient hydrogen fueling stations. However, scaling up such infrastructure poses unique challenges that require innovative solutions. In our new white paper, “How to Effectively Control Flow of Hydrogen Fuel to Improve Safety, Reliability, and Fueling Rates at Dispensing Stations,” we delve into these challenges and explore potential solutions for scaling hydrogen fueling infrastructure.
The Top 4 Key Performance Indicators (KPIs) to Improve Your Next Outage
Capturing the performance of the overall outage, measuring the effectiveness of the strategy, benchmarking for maintenance and reliability comparisons, and updating the customers’ documentation are crucial to the success of future events and plant operations between them. If overruns occurred, the source of those overruns should have already been approved prior to execution but should be part of the review process as well. This will be fed into the lessons learned documentation.
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.
