Reformation feed temperature
Thread Content
Why is it required that the temperature of the reprocessing material reach 480 degrees before it enters the heating furnace? Is it to reflect something?
Both UOP and domestic processes require a feed temperature of 370°C; IFP seems to require a higher temperature, but it shouldn’t reach 480°\ud83d\ude31
The temperature right at the outlet of the heat exchanger is 485 degrees
According to the general operation manual, UOP requires an inlet oil temperature of 370°C, while IFP requires an inlet oil temperature of 400°C℃； After the oil is fed in, UOP requires a gradual temperature increase to 482°C, while IFP requires a gradual temperature increase to 480°C. Personally, I think 480°C is a temperature at which reformation reactions occur significantly and hydrogen is produced.
Another point to consider is that 480°C may result in fewer side reactions at low reforming loads, thereby preventing the production of excessive cracking products. It’s just my personal guess; I’m waiting for an official answer~
We are from Axens, and a minimum feed temperature of 430°C is required. Indeed, 480°C is a critical threshold; once the feed rate reaches 60% of the maximum level, the hydrogen production rate changes significantly at 480°C. The hydrogen production rate remains very low between 430°C and 450°C
