What methods are used to determine whether the conversion temperature at each section of the converter is at its optimal level?
What other methods are there besides the “maximum difference method”? I hope fellow sailors can help add more to it
From the perspective of production operations, the maximum temperature difference method is the simplest and most effective approach, provided that the inlet temperatures of each section are within a relatively reasonable range. Professionally, first evaluate the activity of the catalyst in each section, and determine an appropriate inlet temperature through simulation calculations. The evaluation of catalyst activity is quite specialized and not universally applicable; most factories should still operate at the preset inlet temperature and make minor adjustments thereafter.
If the gas conditions are within the design range, the inlet temperature should preferably be set according to the designed operating conditions； If the deviation is significant, such as during low-load or overload operation, corresponding adjustments need to be made based on the actual conditions.
