If the intermediate-pressure reactor in the hydrogen production plant overheats, can medium-pressure steam be introduced?
Thread Content
Have any of you technicians carried out such modifications before? ? ?
Is the medium-pressure steam introduced directly? It doesn’t seem to have been modified in this way; it’s necessary to determine the cause of the overheating – high inlet temperature or excessive reaction heat – and take measures accordingly based on the specific situation
Medium-pressure steam cannot be introduced directly; what is the cause of the over-temperature? (1) If the inlet temperature is high and the CO level at the medium-temperature conversion outlet is within acceptable limits, reduce the inlet temperature. (2) If the medium-temperature conversion catalyst has reached the end of its useful life, considering replacing it may be an option. (3) If the CO level at the medium-temperature conversion inlet is high, check the performance of the conversion catalyst, whether the water-to-carbon ratio is too low, whether the online display of the water-to-carbon ratio is accurate, and whether the temperatures at the inlet and outlet of the conversion process are appropriate. In short, a comprehensive analysis based on the specific circumstances is necessary to determine the appropriate course of action.
It’s theoretically feasible. It’s not clear yet whether it’s actually useful in practice. The main question is what the specific overheating conditions under medium load are; could you provide a detailed explanation? Parameters such as gas volume, load, catalyst packing size, inlet bed temperature and outlet temperature, pressure, and hydrogen production scale are considered, followed by a comprehensive evaluation. Generally, in medium-temperature cases, overheating doesn’t occur, right? As an exception, you can contact the manufacturer of the medium-temperature catalyst to inquire about the relevant details.
