Diesel hydrogenation temperature rise
Thread Content
I would like to ask, in a diesel hydrogenation unit, for the temperature rise of the bed layer, whose temperature is it compared to?
Temperature difference between the highest point of the bed layer and the reactor feed
The temperature rise of each bed layer is compared with the feed temperature!
. . . . . Between bed layers – there is the temperature rise within individual bed layers, as well as the overall temperature rise of the reactor as a whole
Is your answer the answer there?
Between bed layers, between the bed layers and the feed, at the reactor inlet and outlet
Our actual production statistics will be based on this
You can take a look at the process package; generally, there are separate temperature measurement points for the temperature rise. The temperature rise occurs between each bed layer as well as within the entire reactor. It’s not just one value – during normal operation, the temperature rise in any single bed layer should not exceed 30, while the overall temperature rise should not exceed 60. This applies to hydrorefining; reforming and cracking have relatively higher values
The temperature rise per bed layer is the difference between the inlet and outlet temperatures of that bed layer, while the total temperature rise is the difference between the inlet and outlet temperatures of the reactor.
