Increased safety through 3D temperature profiling
Use in hydrotreater and isomerization units
A producer of sustainable aviation fuel and renewable diesel seeked to increase safety of seven green field catalytic bed reactors (Isomerization, Hydrotreatment, Hydrogenation, Pre-Reformer) in their plant. Overall, safety was the most important point, as the devices would be used in the reactors with hazardous media, high temperature and pressure.
Benefits
Increased process efficiency through intelligent, 3-dimensional sensor routing
Less invasive solution without dedicated ring support frame
More efficient process flow through the catalytic beds
No need for disturbing additional support structures
Undisturbed media flow through the reactor beds
The challenge
The harsh process conditions of approximately 58 bar and 400 °C (752 °F) under which the reactors are operating, as well as the presence of corrosive chemicals such as Hydrocarbon and H2, called for a robust and long-lasting solution.
Our solution
Endress+Hauser manufactured a highly complex Temperature Engineered Solution. Special alloy material and the iTHERM TMS02 MultiSens Flex in advanced design were the perfect recipe for a long-lasting and safe solution. The customer’s material expert selected a suitable special alloy, while Endress+Hauser engineered the thermometer design. The thermometer was chosen without protecting thermowells or a guiding tube. A special MgO cable with extra thick walls is in direct contact with the process.
