Emerson’s Horst Balau presented Solving the Fugitive Emission Challenge for Isolation Valves at the 2024 Emerson Exchange Conference in Düsseldorf, Germany.
Valves, Actuators & Regulators
Digital Valve Controller Employs Edge Computing
Valve controllers play a vital role in industrial processes, ensuring that control valves are positioned accurately under changing process conditions. Building upon fifty years of valve controller improvements, the new Fisher™ FIELDVUE™ DVC7K digital valve controller...
New Noise Reduction Technology for Gas Pipelines
Natural gas pipelines tend to produce loud noise as gas flows through pressure regulating valves. This is usually not a problem in isolated locations, but when neighborhoods develop or expand nearby, it becomes a pressing issue. Our article in the January 2024 issue...
Power Industry Valve Application Video Series
Valves are critical in many power industry applications such as boiler feedwater & recirculation, superheat attemperation, turbine bypass, and more. In this YouTube Fisher Valves & Instruments Power Industry Application Series, you can learn about the role...
Control Valve Challenges in Carbon Dioxide Transport and Sequestration
As climate change progresses, reducing greenhouse gas (GHG) emissions, particularly carbon dioxide (CO2), is critical. Spurred by government subsidies and mandates, CO2 sequestration projects are underway across the globe. My December 2023 Automation.com article,...
Finding the Value in Control Valve Data
In a world awash with digital data, many tend to assume that more data equals more value, but the reality is that data only becomes valuable when it is analyzed and acted upon. In my article titled “Transforming Valve Data into Dollars,” published to Automation.com in November 2023, I discuss a new software application that converts raw control valve data into actionable information.
Gain Asset Health Insights with Emerson’s Digital Valve Controller
Control and on-off valves carry out critical functions in process plants and facilities worldwide, so their performance and condition must be closely monitored. New digital valve controllers provide this functionality, along with other tasks, improving the operation and uptime of these valves. These controllers also enable optimization of maintenance activities by predicting failures well in advance, allowing for proactive instead of reactive actions.
Mitigating Shutdown, Turnaround, and Outage Issues
For the greatest odds of success, plants should plan STOs well in advance and employ the strategies discussed above to secure necessary parts and labor. Knowledgeable external partners can assist in evaluating plant needs, identifying required parts, and overseeing work within their areas of expertise.
Detecting Bellows Damage in Pressure Relief Valves
Pressure relief valves (PRVs) provide critical overpressure protection in many industries by venting excess process media when necessary. PRVs often include bellows in applications with relief valve headers subject to backpressure, but bellows may be damaged by cycling or corrosive chemical applications, causing significant performance impacts and environmental leakage that may go unnoticed for years.
Pneumatic Controllers Revived by Flexible, Configurable, Digital Process Controller
Emerson’s Fisher Instruments has been producing its Wizard pneumatic controllers since the 1940s, refining and revamping them every 20 years or so. Along the way, the company produced its electro-pneumatic controllers, and more recently developed its Fisher™ FIELDVUE™ digital pneumatic controllers (DPC). In all, Emerson estimates there are more than 1 million of its pneumatic controllers presently operating.
Advanced Diagnostics for Electric Actuators
Modern electric valve actuators offer far more than their simpler predecessors, and as a result they are seeing widespread adoption throughout the process industries. Advanced monitoring software provides early notice of developing problems as well as actionable suggestions, empowering maintenance teams to intervene and prevent production impacts.
Easy and Effective Oil Separator Retrofit Improves Operation
The L2t Liquid Level Controller solution is straightforward and inexpensive to install in existing oil separator vessels, and it significantly reduces maintenance and lost production costs, especially compared to level switch solutions. It is also emission free, a significant improvement over systems using natural gas as a motive force.
