Butterfly Valve for Diverse Throttling and On-Off Applications
References to the use of butterfly valves date back to James Watt, who: …made use of a butterfly valve in his steam engine, and the first Mercedes car built around 1901 introduced a butterfly valve in the fuel intake linked to the accelerator pedal. Wikipedia...
Integrated Oil and Gas Well Testing
Testing the composition of oil, gas, basic sediment and water has historically been a batch-type operation where the flow from a single well has been diverted from a header leading to the production separator over to a test separator. These components are measured in...
Measurement and Final Control Technology Announcements from OTC
The news was flowing fast and furiously from the recent Offshore Technology Conference (OTC) in Houston, Texas. I wanted to highlight some of the news from Emerson in case you missed it. To help protect subsea well and pipeline integrity and support...
Corrosion-Resistant Materials in Chemically-Hostile Valve Applications
When it comes to instrumentation and final control elements that touch the process, materials of construction are one of the critical selection criteria. In a whitepaper, PPS Outshines Stainless Steel in Chemically Hostile Valve Applications, Emerson's Steve Attri...
Managing Pressure and Temperature on Oil and Gas Well Pad Burners
In oil and gas production and transportation, managing temperature and pressure is critical for safe and efficient operations. In a whitepaper, The Significance of Reliable Pressure Control in Oilfield Burner Systems, Emerson's Deepak Sivanandan describes the...
Control Valve Suitability in Safety Applications
Sometimes an email exchange turns up something developed years ago that still has great value. So is this case with an article I received as an attachment on final control elements and their suitability in safety instrumented functions (SIFs), a.k.a. safety loops. The...
Complying with Storage Tank Emissions Regulations
If you're an energy producer here in the United States, you likely already familiar with the Environmental Protection Agency's "Quad O" regulations, or officially, EPA Title 40, C.F.R. Part 60, Subpart OOOO—Standards of Performance for Crude Oil and Natural Gas...
Interactive Demonstration of Pressure Regulators in Action
Controlling the pressure levels is one of the challenges many instrumentation and automation engineers face. Pressure regulators are often used for this task, since they are self-regulating and don't require a control loop connected to the plant distributed control...
Testing and Evaluating Pressure Regulator and Relief Valve Applications
Let's close the week with peek into the labs where pressure regulator and relief valve testing is done. In this 4:21 second YouTube video, Emerson Lab Overview, the team managing the lines of regulator technologies provide a look at the test labs and share examples of...
Pressure Regulator and Control Valve Best Fit Applications
Managing pressure is a fundamental control challenge for most process manufacturers and producers. A frequent question is whether a pressure regulator or control valve is best for a particular application. At last fall's Emerson Exchange, I live-blogged a great...
Basics of Flame Arrestor Technology
In process operations with combustible gases, flame arrestors are devices that help mitigate the risk of combustion. Wikipedia defines these devices: A flame arrester (also spelled arrestor), deflagration arrester,[1] or flame trap[2] is a device that stops fuel...
