Field Device Local Display in Process Safety Applications
Jim Cahill
One of the great things about conferences such as last week’s Emerson Exchange Americas conference is reconnecting face-to-face with people where some time has passed. I had the chance to connect with Emerson’s Riyaz Ali , whose expertise I’ve highlighted in several digital valve controller and safety-related posts . He shared a story where he was recently asked about having local valve diagnostics access in the production…

Get better quality data from your wells and increase well production with a smaller package footprint? Possible!
Dexter Huerto Jr.
For those involved in onshore of offshore, well testing & production manifold, I came across some interesting figures: 78% of Oil & Gas E&P projects suffer cost overruns and delay (data from - Oil & Gas Industry MegaProjects: Independent Analysis, Inc., April 2012. Based on data from 130 Oil & Gas megaprojects.) Reducing the topside weight of deepwater structures could save $250,000 / meter of water depth, an average…

Why failure rate for electric actuator in Refinery Coker Plants are very high?
Dexter Huerto Jr.
Operations in any refinery’s delayed coking unit are extremely harsh for any electrical equipment. High temperature can overheat circuit boards, strong vibration can disconnect equipment wiring, fine dust can clogge moving parts. If you have been using actuators to control delayed coking batch processes, you may have had several actuator breakdowns already. This article / prove result case study co-authored by a customer…

Retrofited Gate Station Handles Large Pressure Drop Safely and Reliably Using Fisher EZH Series Regulators
Celestine Lim
Process engineers are concerned about maintaining gas supply when the pressure drop is large. This can happen during gas transmission from wellhead to gas stations and other users. There is also an increasing challenge of reducing capital and operation costs for improved performance and cost-effectiveness of gas stations' processes and operations. Wisconsin Public Service Corporation was facing these challenges when…
