What causes the large radial temperature difference in link Alcohol? In a certain ammonia synthesis plant, the high-pressure intercondenser tower features two shafts and two diameters. Sections 3 and 4 have a radial structure. During production operation, the radial temperature difference reaches 40°C. What is the reason? What is the relationship with air velocity, CO, and CO2?
To what extent do the levels of CO and CO2 affect the temperatures in the three-stage radial bed?
A higher total carbon level results in a smaller temperature difference
I believe the fundamental reason for the large radial temperature difference is the phenomenon of flow deviation in the catalyst packing; moreover, this flow deviation becomes more severe when the gas flow velocity is low, which leads to uneven reaction temperatures. If the gas flow velocity is high enough, or if the total carbon content of the gas is high, as mentioned by the original poster, it may be possible to reduce the radial temperature difference.
It has been in operation for 3 years, and the temperature difference in regulating the total carbon content has improved.
