To minimize coking and maximize the conversion rate in a steam cracker, olefin producers need to closely monitor the furnace’s coil outlet temperature (COT). Various types of sensors measure this key parameter . WIKA USA tested the common sensors designs to evaluate …
At the 2025 AIChE (American Institute of Chemical Engineers) Spring Meeting, Alina Green presented WIKA's unique R&D evaluation of critical ethylene steam cracker coil outlet temperature (COT) sensor designs and installation best practices. The following is …
WIKA designed a multipoint thermocouple array specifically for easy retrofitting into an existing amine contactor column at a Gulf Coast refinery. We customized the length so that there was a measuring junction at specific tray heights, then we threaded the array …
WIKA USA recently had the privilege of partnering with Chevron to custom-build multipoint thermocouple arrays for their refineries’ contactor columns. A chemical specialist from WIKA and a process control engineers from Chevron jointly presented the following …
At a Texas-based syngas plant, the thermocouples in its partial oxidation units were lasting an average of three months before failing. But after switching to WIKA’s TC84 platinum thermocouple with sapphire protection tube, the facility has not had to replace its …
