Wellhead Electrification Drives Optimization Program
Jim Cahill
At the 2022 Emerson Exchange conference, Prabhat Behera from Occidental (Oxy) shared insights and lessons learned from a wellhead electrification project. Puffer-Sweiven’s Jack Lee and Emerson’s Damian Trujillo joined him to provide additional context on the integrated model that brought together the application, product and services. Here is their session abstract: Shutdown valves installed at the wellhead for oil…

Reduce Waste & Increase Efficiency in Clean-in-Place Processes
Jim Cahill
While the idea of adding costs to a food and beverage or pharmaceutical industry process like Clean-in-Place/Steam-in-Place (CIP/SIP) has not traditionally been an easy decision, in today’s industrial environment that has changed. With the retirement of experts, the lack of availability of workers, the increase in materials costs and narrowness of margins, the principal way for food and beverage and pharma companies to…

Avoiding Actuator Damage from Failed Components
Jim Cahill
Manufacturers and producers must think through their process safety on ways to mitigate risks against failure conditions in the components within a basic process control system (BPCS) or safety instrumented system (SIS). For instance, failures can occur on air filter regulators (AFRs) on valve actuators. I mention this because I connected with Emerson’s Riyaz Ali , who had a discussion with a major international oil company…

Partial Stroke Tests and Diagnostics for Emergency Shutdown Valves
Jim Cahill
Emergency shutdown valves perform the work of bringing the process to a safe state in the event of a hazardous condition. They must be periodically tested, because, unlike other valves, they may sit dormant for a long time. This 2:22 YouTube video, Emerson TopWorx DX PST with HART 7 , explains how this partial stroke and emergency shutdown valve controller controls and monitors these shutdown valves. To test the capability…

I recently had an article published in the August 2022 issue of Hydrocarbon Processing. It is titled “Why Compact Actuation Solutions are Ideal for Constrained Space Installations,” and it discusses how a vertical profile actuator is providing new opportunities for space-constrained applications. A summary of the article follows. Space constraints are common in the oil and gas industry. However floating production,…

Driving Combined Cycle Efficiency Gains
Jim Cahill
Combined cycle electrical power generation facilities play an essential role in providing baseload power to the grid. The principle of operation : …is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually, the heat passes through a heat exchanger so that the two engines can…
