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
Ravi Jethra | 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 …
Accuracy and Response Times for Thermocouples, Thermowells and Other Temperature Instruments for Syngas Plants
Robert Torgerson | Know-howEach temperature measurement system on the market has its particular features and limitations. When deciding which ones to use in syngas plant reactors, it is important to take into account the response times, accuracy, and other specifications of thermocouples, …
