Gain Asset Health Insights with Emerson’s Digital Valve Controller
Jim Cahill
In many applications, control and on-off valves are subjected to regular position changes and constant contact with process media, causing wear and tear that must be monitored to prevent operational issues. Control valves are typically operated with a 4-20mA signal sent from a remote automation system, but without valve position feedback, drift from the intended setpoint can occur. On-off valves are simpler to control…

Mitigating Shutdown, Turnaround, and Outage Issues
Jim Cahill
Plant shutdowns, turnarounds, and outages (STOs) have never been simple, but in recent years they have become even more challenging due to labor shortages and difficulties procuring parts. My article in Processing , titled “ Rethinking shutdown, turnaround, and outage planning ,” discusses the impacts of these challenges on STO planning and execution, and it offers strategies to minimize their effects. Increasingly…

Detecting Bellows Damage in Pressure Relief Valves
Jim Cahill
Pressure relief valves (PRVs) provide critical overpressure protection in many industries by venting excess process media when necessary. PRVs often include bellows in applications with relief valve headers subject to backpressure, but bellows may be damaged by cycling or corrosive chemical applications, causing significant performance impacts and environmental leakage that may go unnoticed for years. My article in…

Advanced Diagnostics for Electric Actuators
Jim Cahill
Due to stringent greenhouse gas emissions regulations, as well as ongoing technical advances, electric valve actuators are proliferating across process industries, but until recently, these actuators have lacked comprehensive diagnostic and monitoring features.

Easy and Effective Oil Separator Retrofit Improves Operation
Jim Cahill
Due to more stringent methane emission regulations, natural gas-powered level control systems in oilfield separators are no longer practical. Thankfully, many of these separators can be retrofitted easily with new electric level control technologies, as discussed in my article, titled “ Improved oil separator control strategies ,” in the October 2023 edition of Process Instrumentation . Please find a summary of the article…

How Reliability Improves Sustainability
Jim Cahill
While high reliability clearly entails high availability, what is less obvious is that reliability also enhances sustainability. My column from the October 2023 issue of InTech , titled “ Executive Corner: Reliability Through the Lens of Sustainability ,” explains why. When devices such as relief or isolation valves do not operate reliably, undesirable emissions can escape to atmosphere, wasting materials and potentially…
