Temperature Measurement Installation Best Practices

My friends managing the Rosemount brand of temperature measurement products have an upcoming series of webinars on installation best practices. These webinars are available in your region of the world no matter where you’re located.

Emerson’s Ryan Leino will describe how the effectiveness of a temperature system (a sensor with a connection head, a thermowell and a transmitter) is dependent upon several factors including proper installation, point-of-penetration, insertion length, mounting, and installation wiring.

For the Americas, the Installation Best Practices webinar will take place on December 2 and 9am CST.

For the European, Middle East and African region, this webinar will occur on December 3 at 13:00 GMT.

For the Asia-Pacific region, this webinar is scheduled for December 5 at 11am SGT. Continue Reading

Monitoring Control Loops for Leakage Current and Increased Resistance

Control systems rely on the signals coming back from measurement devices to perform control operations and provide feedback to operators. Unfortunately the signal from these devices can be impacted by several conditions.

These conditions include damage and corrosion, water or condensation in the junction box or terminal compartment, power supply deterioration and grounds or electrical shorts.

This 4:08 YouTube video, Rosemount 3051S and 3051 Pressure Transmitters – Power Advisory Diagnostic, shows how these Power Advisory Diagnostics continuously monitor the electrical loop to detect changes that compromise the integrity of the transmitted 4-20 mA output signal. Continue Reading

Power Plant Monitoring

Wireless measurement devices are nothing new and installations are in just about every industry, including power. From my experience, power plants don’t choose to use wireless technologies to replace wired devices, rather they are used to solve some of those monitoring applications where the cost of laying copper is simply too expensive.

Those utilities that have deployed the technology in monitoring applications have found the additional data helpful to operations. One customer had a problem with strainers clogging on raw water intake piping and used wireless pressure transmitters to detect plugging.

This simple measurement prevented a constant maintenance problem. Another plant uses wireless devices as a means to better manage ash ponds and gain early insight into any changes at these ponds. Still others are using acoustic devices to track leakage from steam traps and relief valves. What users are finding is that the technology is very robust and that once a wireless system is in their plant, it’s easy to identify and add incremental monitoring points. Continue Reading

Hardware in the Loop Simulation for Process Control

Emerson’s Felipe Fakir shared a whitepaper with me, Hardware in the Loop Simulation for Industrial Process Control, which he and colleagues attending São Paulo State University in Brazil had written. Their abstract [I’ve added hyperlinks]:

Real-time simulation for control loop design and operators training systems (OTS) are increasingly being used in the process industry due to some advantages as safety, repeatability, comprehensiveness, and reduced cost and time of development. One technique to perform real-time simulations is HIL – Hardware-In-the-Loop, which consists in the simulation of an industrial process part operating in real-time with real equipment belonging to the control system.

HIL addresses the use of a dedicated hardware for real-time model simulation and communication interface with control systems. This whitepaper highlights the use and discusses the benefits of the HIL technique for industrial process control. The process dynamic model, a coupled tank industrial process, was designed in the Mimic simulation software and downloaded in to a real-time hardware, VIM [Virtual IO Module], for process simulation purpose.

This process model is integrated to the DeltaV distributed control system (DCS), designed to perform process control. By using the HIL solution, it is possible to enable OTS of industrial control systems, besides simulating the behavior of industrial processes with different controller tuning, reducing risks, tuning and startup times of automation systems.

The authors open noting benefits simulation for automation system suppliers:

…such as reducing costs with prototyping, possibility to testing systems under different conditions with high repeatability; and as a result optimizing processes and product development…

They highlight the three most known simulation techniques—the first two considered real-time simulations: Continue Reading

Improving Oil and Gas Production Separation

One of the most basic functions in an oil and gas production process is the separation of the oil, gas, basic sediment, and water. The production separator handles this function. This separation step in the process allows the flow or production rate of the individual component streams to be measured, providing essential information on the quantity of fluids produced from each well in the field.

The challenge for oil & gas operators is to perform this separation while minimizing production allocation errors, maximizing separation efficiency, and reducing gas sent to tanks and flare.

In this 47-minute recorded webinar, Key Considerations for Improving Production Separation, Emerson’s Michael Machuca shares how to address these challenges and in addition to offering ways technology can assist in avoiding royalty disputes, avoiding health, safety and environmental (HSE) risks to help you meet production plans, maintain compliance, and reduce your overall operating costs.

Improving-Production-SeparaIn this webinar, Michael highlights many of the common issues in operating separators and heater treaters including causes and their impact on the process.

For onshore well pad sites, the measurements taken after the separation has taken place are used to pay royalties to landowners. There are legal risks when measurements don’t match what is in the tank. Poor separation can cause lost gas to sales and frequent trips by personnel to the well pad site. And, without good data, it’s difficult to make production management decisions to optimize production levels.

Michael shares some examples and financial impacts of potential problems including increased separator backpressure deferring production, produced sand eroding flowmeters, and excessive flaring caused by separator carryunder. Continue Reading
