Managing Pressure and Temperature on Oil and Gas Well Pad Burners
Jim Cahill
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 technologies critical in managing process temperatures and pressures. Deepak opens by highlighting the integral role of burners on oil & gas well pads: …

Control Valve Suitability in Safety Applications
Jim Cahill
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 article, When SIL suitability is required for final control elements , was written by Emerson’s Riyaz Ali back in 2011 for EngineerIT magazine. The…

Complying with Storage Tank Emissions Regulations
Jim Cahill
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 Production, Transmission and Distribution . The EPA defines its purpose: This subpart establishes emission standards and compliance schedules for the control…

Interactive Demonstration of Pressure Regulators in Action
Jim Cahill
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 system (DCS). I saw this post, Pressure Regulator Animations by Emerson’s Michael Calaway in the Emerson Exchange 365 community. He shares links to some…

Testing and Evaluating Pressure Regulator and Relief Valve Applications
Jim Cahill
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 testing performed. This testing on pressure regulators and relief valves helps to assure successful operation when the regulators are placed into service…

Pressure Regulator and Control Valve Best Fit Applications
Jim Cahill
The post Pressure Regulator and Control Valve Best Fit Applications appeared first on the Emerson Process Experts blog. 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 presentation by Keith Erskine with Emerson…

Basics of Flame Arrestor Technology
Jim Cahill
The post Basics of Flame Arrestor Technology appeared first on the Emerson Process Experts blog. 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 combustion by extinguishing the flame .

Does Flow Loop Make Valve Positioner Unnecessary?
Jim Cahill
In the Process Control LinkedIn group, a question was asked : Positioners seem very popular now, but most lines with valves have flow meters attached. Won’t a flow loop make the positioner redundant? When asked for clarification, the original poster explained: As far as I understand them, a positioner simply moves the stem to a particular position governed by the control signal (unlike a ‘non-positioner…

Automating Manual On-Off Valves
Jim Cahill
The post Automating Manual On-Off Valves appeared first on the Emerson Process Experts blog. Unless your plant or production facilities was recently built, chances are that your process has a mix of automatic and manual control. A common area for manual control are on-off valves used in many general purpose applications such as tank filling and emptying, filter backwash and blowback, and sequencing operations to name…

Refinery and Chemical Plant Pressure Regulator Applications
Jim Cahill
Pressure regulators play an important role in process operations. Wikipedia describes their operation : A pressure regulator’s primary function is to match the flow of gas through the regulator to the demand for gas placed upon the system. If the load flow decreases, then the regulator flow must decrease also. If the load flow increases, then the regulator flow must increase in order to keep the controlled pressure…

Safety Instrumented System Solenoid-Operated Valve Approaches
Jim Cahill
Last week at the Emerson Exchange conference, I caught up with Emerson’s Riyaz Ali . You may recall Riyaz from many safety instrumented system-related posts . We discussed some of the trends in integrated positioners + solenoid valves + limit switches + valve position transmitters. Riyaz Ali Senior Business Development Manager Riyaz felt that this approach not in line with the safety instrumented system (SIS) general…
