The Float Switch: A Simple, Reliable Measurement Method for Almost All Liquid Media
Patrick McGrath | Know-howDue to its reliability, a float switch is one of the most frequently used measurement technologies for monitoring liquid media levels. It's simple yet effective design consists of a hollow float within a guide tube, rising and falling with liquid levels and activating …
The Role of Thermocouple Sensors in Catalyst Die-Off Predictions for LTS Syngas Reactors
Robert Torgerson | Know-howBy using thermocouple sensors and plotting temperature measurements at different points in the catalyst bed, syngas plant operators can accurately predict catalyst behavior. The resulting “S” curves – along with shifts and shape changes over time – also give …
Diaphragm Seals Improve Reliability in Bioethanol Production
Hardy Orzikowski | Know-howIn bioethanol production processes, engineers must closely monitor pressure, temperature, level, and flow in order to ensure safe and efficient operations. Diaphragm seals in these applications do double duty: protect pressure measurement instruments from the medium, …
Temperature Measurement: An Effective Tool for Monitoring Catalyst Performance
Robert Torgerson | Know-howRefineries rely on accurate temperature measurement and monitoring for information about catalyst performance and remaining catalyst life. The key measurements in a syngas (synthesis gas) shift reactor are 1) approach to equilibrium temperatures and 2) exotherm …
