Refineries rely on multipoint thermocouples to monitor temperature at different points inside fixed-bed reactors. However, these temperature measurement systems are also extremely useful for evaluating performance in fluid catalytic cracking (FCC) units, vapor …
Refinery operators who work with fixed bed catalysts place a high value on temperature accuracy, but they also don’t want to waste time by taking unnecessary temperature readings. Thus, to better understand any radial temperature differences that may exist during …
With repeated exposure to high temperatures, a Type K thermocouple becomes less accurate. Aging is a phenomenon that results in higher-than-accurate temperature readings, while drift results in lower-than-accurate readings. While all Type K thermocouples experience …
Advancements in thermocouple assemblies allow syngas plants to easily update their temperature measurement solutions for low temperature shift (LTS) applications. With improved monitoring of catalyst activity, syngas plants can maximize catalyst life and better plan …
By 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 …
