Emerson's Carsten Thoegersen and Emanuele Rivolta shares his expertise on high-integrity pressure protection systems in process safety applications. Their abstract: HIPPS (High-Integrity Pressure Protection System) is a part of the Safety Instrumented System (SIS) &...
Final elements such as safety shutdown valves, emergency isolation valves, blowdown valves, etc., in safety instrumented functions (SIFs) are equipped with various accessories such as digital valve controllers, solenoid valves (SOV), and volume boosters, to name a...
A recent ControlGlobal.com article explored the energy savings of variable frequency drive (VFD)-based centrifugal pumps versus control valves in flow control applications. The article, Eliminating the Control Valve sums its position in the subtitle, "Valves Are...
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...
Emerson's Mike Boudreaux shared a Control Engineering Asia article written by the renowned process safety expert, Paul Gruhn. The article, Providing Process Safety, analyzes some of the latest trends in safety instrumented systems (SIS) designs for the process...
The March/April edition of Intech magazine features an article by ModelingAndControl.com's Greg McMillan--Key design components of final control elements. The article is derived from Greg's new book, Essentials of Modern Measurements and Final Elements in the Process...
Recently at the International Health, Safety, Environment, and Loss Prevention Conference in Kuwait, Emerson's David Walker had the opportunity to present on the topic of process safety. His presentation, Using a Smart Safety Instrumented System (SIS) to Make Better...
If ever there were a need for dynamic control, it would be for the global bond and equity markets this week. Instead of tackling that global challenge, with today's post I'll highlight Emerson senior process control consultant Mark Coughran's Emerson Exchange...
