Riyaz Ali provides clarity on when to assign the SIL suitability for valves used in different scenarios (process control vs. safety shutdown) and establish criteria to assign SIL applicability for the “Final Element”.
Emerson’s Kevin Thomas discussed corrosion and erosion monitoring at the 4C Health, Safety & Environmental conference. Kevin opened citing some statistics.
At the 4C Health, Safety & Environmental conference, Emerson’s Derek Kelly highlighted ways to reduce fugitive emissions from tank venting equipment.
At the 4C Health, Safety & Environmental conference in Austin, Emerson’s Ed Schodowski and Doug White presented on ways to address safety issues that relate to process , loss of containment and occupational trends, regulations and other factors that affect plants.
Level and temperature measurement technology plays a key role in modern liquefied natural gas (LNG) tank gauging systems. In a Control Engineering Europe article, ‘Increasing safety and optimizing tank usage at LNG terminals’, Victoria Lund Mattsson, a solutions...
A key conference for health, safety and environmental (HSE) is the 4C Health, Safety, and Environmental Conference. The 2021 conference will take place next week, August 18-20 here in Austin, Texas.
Traditional safety systems have a centralized architecture, meaning that a large processor unit runs hundreds of safety instrumented functions (SIF). Modern safety systems have a distributed architecture where multiple smaller processor units execute dozens of SIFs....
In a recorded webinar, Smart Electric Valve Actuators for Critical Fail-Safe Applications, Emerson’s Knut Riegel and Umberto Bianchi share how these actuators are well-suited for emergency shutdown (ESD) applications.
Vortex flow measurement is uniquely adaptive when it comes to handling difficult applications. By virtue of its science, utilizing the von Kármán effect, these instruments are accurate across a wide operating range and effective at withstanding high process pressures...
I received a question from a very old post here on the blog, Credit for Partial Stroke Tests in Verification Process. The person was trying to get a better understanding about this chart showing how partial stroke tests (PSTs) can extend the intervals between full stroke tests for final elements in a safety instrumented function (SIF).
Organizations have come to expect that their control systems will operate for many years and often anticipate using the same systems for decades. New improvements in cloud computing coupled with rapid advancement of control system technology has many people wondering...
At the Emerson Exchange Americas virtual series, Emerson’s Mike Hoyme and Stanley Af demonstrated diagnostics in the final elements within a safety instrumented function.
