Highly secure connections to plant automation systems and intelligent field instruments are enabling Emerson to provide remote monitoring services, helping processing companies and manufacturers to achieve significant operational benefits without having to develop in-house data analysis expertise.
Pressure Relief Valve Continuous Monitoring for Affirmative Defense
Emerson’s Marcio Donnangelo and Marcelo Dultra presented Reducing Data Complexity on Affirmative Defense Claims with PRV Monitoring System at the 2022 4C HSE Conference.
Cutting Control Valve Noise
The modal attenuator consists of a series of carefully engineered resonant cavities to provide sound reduction across a wide spectrum of frequencies. The full-bore design allows unrestricted flow, and internal drain channels drain off condensate which could build up in the device and reduce performance. Installed just downstream of the valve, the modal attenuator achieves an overall sound reduction up to 15 dBa, while creating no restriction in flow capacity whatsoever. The device can be used on existing valves or paired with a low noise control valve to achieve even higher levels of noise reduction. Unlike diffusers or silencers, the modal attenuator works consistently across a wide range of flow rates.
Reduce Fluid Flow Noise Without Pressure Drop
In this 9:51 video, Fisher WhisperTube Product Demo, Emerson’s Shelby Daniels explains in detail how this technology is a passive reactive silencer that reduces system noise across a wide range of conditions without impacting the flow capacity or process.
Reduce Process Noise Without Pressure Drop
The Fisher WhisperTube Modal Attenuator addresses these issues for sound suppression in pipeline and control valve applications. It has a straight-through flow geometry with an inside diameter (ID) that matches the pipe ID and is installed in place of a spool piece. It creates no additional pressure drop.
Duke Energy Addresses Attemperator Issues
Duke Energy’s Heat Recovery Steam Generator Engineer Eugene Eagle and Emerson Automation Solutions’ Director of Steam Conditioning Group Justin Goodwin Power Engineering article, How Duke Energy Addresses Attemperator Issues, describes the deployment of a new steam atomization attemperator design that allowed Duke to reliably and safely run their combined cycle units at very low load conditions.
The Future is Now for Predictive Valve Maintenance
Saurabh Pathak & Naman Tahan share how advances in digital valve controllers, diagnostic software & network communications are enabling significant reductions in maintenance costs & unplanned outages.
Improve Carbon Sequestration with Proper Valve Selection
In a Hydrocarbon Processing magazine, Control Valves for Carbon Sequestration Applications, Joe DeMonte and Suzanna Grills share how control valve selection for these projects can be challenging, but achievable with the right level of support.
Reducing Valve Emissions to Drive Sustainability Improvements
In a Fugitive Emissions Journal article, ESG Improvements Through Emissions Reduction: Issues and Opportunities, Emerson’s Bruce Ofori shares how new technology adoptions, and reviewing outdated practices and equipment retrofits, can build stakeholder confidence with respect to the reporting of greenhouse gases (GHG) emissions, volatile organic compounds (VOC), and hazardous air pollutants.
Optimizing Valve Compressed Air Consumption
For air-operated control valves, the pneumatic power at a constant supply pressure is proportional to the mass flow rate of instrument air. The pneumatic/eletro-pneumatic/microprocessor-based digital valve controller is used on most control valves operated in closed-loop control, where the input signal is continuously changing.
Pick the Right Control Valves for Ethylene Service
In a Hydrocarbon Engineering article, Control Valve Selection for Ethylene Plants, Matthew Wagner describes how to choose the right combination of valve style, trim type, materials of construction, and digital positioners for critical valve application in an ethylene unit.
How Advanced Automation Technology Helps to Increase Capacity at LNG Regasification Plants
The owners of LNG regasification terminals are looking for ways to increase the operational efficiency of their assets while still ensuring that safety is never compromised. The application of a broad range of advanced digital technologies is helping them to meet this challenge and increase capacity at their plants.
