Let's end this short week for the United States of America's 4th of July Independence Day holiday with an educational video from Emerson's Fisher Valves & Instruments YouTube channel. The video, Control Valve Sizing Basics: What is Pressure Drop?, describes what...
Given the possible harm to the equipment, a special surge prevention algorithm is required to efficiently protect the compressor. The controller response time also must be higher than for majority of other control loops. The Emerson DeltaV PK controller is a good example of fast-acting controller for compressor antisurge control.
The Drive Gain diagnostic value that a Micro Motion Coriolis meter from Emerson reports is a very good indicator of when there is gas vapor in the oil leg. That is why is it important to monitor, because it can tell you very definitively if the oil leg on your separator is experiencing gas carry-under.
Fuel gas drives the boilers, fired heaters, generators, compressors and more in many process manufacturing and production operations. Accurately controlling fuel gas pressure is important for optimum combustion and overall energy efficiency. I received a draft of an...
Back in 1974, the ASME (founded as the American Society of Mechanical Engineers) published a performance technology standard for thermowell calculations as well as overall temperature measurement best practices, PTC 19.3. Based on decades of industry and research...
