Has there been any change to the over-temperature interlock for the hydrogenation reactor?

There is a question: has there been any change in the over-temperature interlock for current hydrogenation reactors? Has anyone seen a temperature difference interlock? If so, please give an example. Are there any special advantages to temperature difference interlocking?

It seems to be a new problem. In our current design, we use temperature difference interlock, which I personally feel is not the best protection method for reactors and catalysts. In practice, it is possible that the temperature exceeds the range permitted by the catalyst, yet the temperature rise remains within a reasonable range. What we have installed is oil hydrogenation.
