POWER-GEN International kicks-off next week (December 13-15) in Orlando, FL. Emerson experts will be available to discuss ways utilities can improve unit availability and achieve more flexible operations. They’ll also share strategies for making shrinking plant workforces more effective. The following are some ways you can connect with them.

Control systems are the heart of manufacturing and production processes. Keeping them operating at peak efficiency while also keeping them secure requires time, energy and focus. Automation suppliers can play a large role in these efforts. News came out today of Guardian Support improvements and simplifications in how DeltaV distributed control system users can better monitor the security and health risks associated with their systems. These enhanced capabilities include:
…updated dashboards and faster access to education and support – increase an organization’s ability to make business critical decisions to improve risk, incident, and lifecycle management.
I caught up with Emerson’s Bob Cruz
who presented along with Yoga Gorur
at the Emerson Exchange conference in Austin this past October. Their presentation, New and Improved Guardian Support Improves Your Lifecycle Costs, describes the Guardian Support program
as a core element in lifecycle services available for customers.
Guardian support enables real-time visualization and management of the control systems and proactively provides critical, relevant, system-specific information to keep them current. For example, many plant staff engineers are hard-pressed to keep with the security updates caused by issues found at various levels of the software stack. There is also fear about what these updates might affect in the running system—is the patch really necessary and if so, how urgently must the system be patched? Continue Reading ▶
When large capital project teams consider the importance of optimizing ongoing operations and asset management in their designs, the results can impact which quartile the manufacturer and producer operates in compared with their industry peers.
In a ControlGlobal.com article, Plantman Go: The future of asset lifecycle modeling, author Bob Sperber surveys automation suppliers for their views on ways to improve capital project performance while keeping an eye on ways to improve operational performance success through the lifecycle of the manufacturing process.
He quotes Emerson’s Jim Nyquist on the challenges with large capital projects:
Today, 65% of projects worth more than $1 billion and 35% of projects under $500 million fail, where failure is defined as at least 25% over budget and/or late by 50%.
To address these financial issues:
Emerson’s Project Certainty, which in part resulted from Emerson’s 2014 acquisition of Management Resources Group, led to a merger of consulting and technology that targets project inefficiencies with a mix of services, methods and technologies. These capabilities include unified project documentation and information (including tag databases and instrument indices) from multiple sources. Project Certainty also uses Emerson’s Characterization Modules (CHARMS) and Smart Commissioning technologies for electronic marshaling with smart junction boxes, which reduces commissioning time for HART and Foundation fieldbus devices by up to 80%.

Centrifugal and axial compressors are at the heart of many production processes. Effective compressor automation and turbomachinery control not only impacts efficiency, but also safety, reliability, production throughput and energy usage. A complete turbomachinery control system consists of measurement devices, high speed controllers, control valves, guide vane drives, turbine governors and more.
I spoke with Emerson’s Mikhail Ilchenko about compressor control. He noted that it’s important to treat this control not as a standalone black box, but as an integrated component in the plant control system.
When well integrated, it provides:
- Safe and efficient antisurge control
- Steam and gas turbine control
- Load sharing between parallel compressors
- Auxiliary device control
- Mechanical state monitoring and diagnostics
- Modifications of pilots and actuators
- Antisurge valve optimization
- Valves and instrumentation diagnostics
- Maintenance procedures optimization
If you’re unfamiliar with compressor surge, it is a phenomenon where flow oscillations inside the compressor are created when the pressure ratio across the compressor becomes so high that it is restricting the gas flow sufficiently to cause a stall. When this occurs, the pressure ratio drops and the compressor recovers the flow direction. If no action is taken, this process repeats again and again. Continue Reading ▶
