Calculation of the equilibrium temperature difference in the Luzzi reactor
Thread Content
As is well known, in Ruchi’s synthesis towers, the aging of the catalyst is generally determined based on the temperature of the bed layers. As the catalyst ages, the temperature at the hot spots gradually decreases. If there are no temperature measurement points within the bed layers, only temperatures at the inlet and outlet are available, how can it be determined whether the catalyst inside the synthesis tower has aged and whether it is necessary to replace it? The converter can have its catalyst activity determined by calculating the equilibrium temperature difference at the conversion outlet, but how is this done for the Ruhr process reactor? I hope experts in this field can provide some guidance. Thank you
Here, we determine whether the activity of the synthesis catalyst is good based on daily analysis of the methanol content and the recycle gas. Generally, the methanol synthesis efficiency is good; as long as the exit temperature of the synthesis tower does not exceed 250 degrees, the catalyst can continue to be used.
It can be determined based on the drum pressure; for example, if it is currently at 3.0 MP, then the hot spot in the bed will be at the saturation steam temperature at that pressure plus 10 degrees.
