A whitepaper, Doubling Up On Safety, explores a two-solenoid safety methodology that lets you exercise your solenoid valve online—protecting your plant, improving uptime, and enabling you to better adhere to functional safety requirements.
In a Hydrocarbon Processing article, “Simplifying Safety Valve Installation and Maintenance”, Kurtis Jensen & Lura Parrent highlight new technologies on how to simplify safety valve installations while improving performance and reliability.
In a Hydrocarbon Engineering article, Improving safety shutdown valve reliability, Emerson’s Stanley Amirthasamy and Lura Parrent share ways to improve the reliability of final elements when they are safety valves. They open noting how safety valves are used to bring a process to a safe state.
Process manufacturers who required heating as part of the process may have several different types of industrial heating equipment. These may include boilers, dryers, furnaces, heaters, ovens, dehydrators and more. The use and upkeep of this equipment is governed by a...
A safety instrumented function (SIF) within a safety instrumented system (SIS) consists of a sensor, logic solver, and final element. As part of the IEC 61511 global safety standard, these elements within the SIF must be tested during the operational phase of the...
At the 2018 Emerson Exchange conference, Emerson's David Tuttle presented Preventing Overpressure Disasters in Supercritical Steam Generation. David comes to Emerson from the Crosby brand of valves that joined Emerson as part of the Pentair Valves & Controls...
Valves are critical components inside of safety instrumented functions (SIFs) since they do the work of touching the process flows to bring the plant to a safe state in the event of a safety demand. In a Valve magazine article, How Valve Selection Can Impact SIS in...
I saw an email string with a question asking if it's possible to detect all possible failure modes in a safety valve if very intensive and intrusive tests, such as full-stroke testing, leak testing, etc. are performed. Would it be conceivable to use 100% proof test...
Imagine leaving some of your portable electronics out on a hot day. Now imagine leaving it out in a desert in the Middle East in the middle of an extremely hot summer. How long do you think it would last? Emerson's David Walker told the story, DeltaV SIS in the Heat...
Safety instrumented functions (SIFs), also known as safety loops, are comprised of a sensor to sense the process condition, a logic solver to decide the safety action to take, and a final element to perform the action. Emerson's Riyaz Ali and I & C Specialist's C...
