With improved monitoring of catalyst activity, syngas plants can maximize catalyst life and better plan for catalyst replacement \u2013 two qualities that reduce downtime and improve the bottom line. Is it time for a thermocouple replacement and upgrade?<\/strong><\/p>\n<p>Catalyst activity in syngas low temperature shifts (LTS) reactors depends heavily on temperature. An accurate and robust <a href=\"https:\/\/blog.wika.com\/us\/\/knowhow\/monitoring-catalyst-performance\/\">thermocouple assembly provides essential information about catalyst behavior<\/a> to:<\/p>\n<ul>\n<li>Optimize performance.<\/li>\n<li>Ensure safe catalyst reduction.<\/li>\n<li><a href=\"https:\/\/blog.wika.com\/us\/\/knowhow\/thermocouple-sensors-catalyst-die-off-predictions\/\">Predict catalyst events and catalyst bed life.<\/a><\/li>\n<li>Plan for catalyst end-of-run and replacement.<\/li>\n<\/ul>\n<p>However, temperature data are only as good as the temperature measurement system in use. Plant operators should know the characteristics and limitations of each type of temperature sensor before deciding which one to use. This is particularly relevant for measurements in LTS applications, where temperature is a determining factor in catalyst reduction and activity. Temperature measurement systems that permit only a small number of measuring points \u2013 or one that limits the measuring points to certain areas, such as the inlet \u2013 may not provide sufficient and representative temperature information.<\/p>\n<p>The latest technologies provide data on temperature gradients and radial spread temperatures. What\u2019s more, thermocouple replacement \u2013 changing out a deficient thermocouple assembly with one that is more versatile and accurate \u2013 is a quick and easy process.<\/p>\n<h2>Think Radial Spread When Considering Thermocouple Replacement<\/h2>\n<p>Some applications may benefit from a higher level of temperature information than a simple gradient. In these cases, a radial temperature measurement system greatly increases the number of measurement points. Radial temperature measurements within the process give not only information about catalyst activity, but are also an excellent tool for diagnosing reactor maldistributions, hotspot formations, and channeling.<\/p>\n<p>In 1987, <a href=\"http:\/\/blog.wika.com\/us\/\/products\/temperature-products\/wika-global-leader-temperature-sensors\/\">Gayesco International<\/a> \u2013 now a division of WIKA USA \u2013 introduced the <a href=\"https:\/\/www.wika.com\/en-us\/tc96_r.WIKA\" rel=\"external\" target=\"_blank\">Flex-R<sup><span>\u00ae<\/span><\/sup><\/a>\u00a0multipoint thermocouple assembly, a breakthrough technology that has become the recognized standard for hydrocrackers around the world. This temperature measurement solution is made up of multiple flexible thermocouples to provide high measuring point density per nozzle. Each point is independent and can be routed anywhere in the reactor. The sensors\u2019 small metal mass allows extremely short response times \u2013 4 to 8 seconds \u2013 and real-time temperature readings.
