Thermal Flow Meters Help Electric Power Plants Keep Their Cool With Hydrogen Gas
In all electric power generation plants (gas, solar, coal or nuclear), the fuel source of choice heats a large boiler, which creates steam that drives turbine blades to rotate. The turbine shaft in turn spins magnets inside the generator, which induces an electrical current in a coil of wires. It’s a high-temperature process both in terms of the boilers and steam, but also at the back end of the process where the electric current generates a large amount of heat that must be managed in order to keep the generator’s wire coils cool enough to avoid degradation or failure. Depending on the MVA size of the generator, hydrogen (H2), air or water is typically used to provide cooling.

Sun-Activated LilyPads Remove Contaminants Without Chemicals
Puralytics LilyPads are hardly noticeable in the ponds, lakes, and catchment areas where they are deployed. Made of mesh and plastic, the flat, 1-meter diameter disks could even be confused for their plant namesake if not for their white color.

Valve Health Diagnostics
Valves are one of the most common assets in the process industry, spanning all verticals. Chemicals, refineries, and petrochemicals, however, will find improved valve health diagnostics useful for critical valves and controllers in their plants, while upstream and midstream oil and gas companies may be focused on much larger, critical valves like pipeline or subsea valves. Using Seeq, process manufacturers are able to implement a condition-based monitoring analysis to monitor valve health across an entire fleet. Engineers can utilize the historical data to accurately create a predictive maintenance forecast and preemptively detect valve failures before they occur.

Here's To Microbrews And POTWs
As local breweries grow in popularity, their initial focus on hand-crafted recipes can quickly shift to business realities such as the costs and logistics of process wastewater treatment. Publicly owned treatment works (POTWs), brewery owners, and consulting engineers all have roles to play in making that trajectory smoother for up-and-coming craft and microbrewers.

Pinpointing Accurate Steam Use In Dynamic Industrial Processes
In commercial brewing — as with other food, chemical, or industrial processes — control over steam heating can have significant influence on process costs and consistent quality in the final product. But its measurement and control can also be impacted by unique circumstances of those applications. Here is how changing just one aspect of steam measurement brought economy and consistency to multiple aspects of a brewer’s overall process.

Community Voices: California Farmers Are Key To Carbon Capture
"Getting to Neutral" by the Lawrence Livermore Laboratory (LLNL) draws a roadmap to California's carbon neutrality by 2045, removing 125 million tons of CO2 emissions from the atmosphere (and the economy). But unlike the actual map of California, LLNL's carbon roadmap barely includes the 27 million acres of cropland and 16 million acres of grazing land. And that's a massive oversight.
