Bottom vapor temperature of the distillation column

What does a high temperature of the vapor phase at the bottom of the catalytic fractionation tower indicate? How to ensure that the gas phase temperature does not exceed
Reasons: 1. A high vapor phase temperature indicates that a significant amount of heat is generated during the reaction. 2. The flow rate of the circulating oil slurry in the distillation system is low, resulting in insufficient absorption of the heat from the reacted oil gases. 3. The internal recirculation in the fractionation system is low, while the upward movement of the gas phase is significant. Processing: 1. Contact the reaction team to adjust the depth appropriately. 2. Appropriately increase the upward flow rate and control heat extraction properly. 3. Adjust the internal reflux flow reasonably to ensure proper fractionation.
The reaction releases a large amount of heat, and this heat cannot be effectively dissipated or removed; it accumulates over time. The answer given above is quite correct. There are many experts like those who posted above on chemical engineering forums, so the original poster should seek advice from them frequently
Additional note: Regarding the economic viability of the key analysis approach outlined in Point 1, if it is more advantageous to remove the heat generated by the reaction by increasing the circulation volume of the oil slurry, or by using cold oil slurry for circulation to remove this heat, thereby reducing the degree of reaction, then fractionation can also be utilized to address the issue of excessively high vapor temperature at the bottom of the fractionator caused by an excess of reaction heat
Hehe, that’s true! The key is to ensure strong communication and coordination among different positions; everyone needs to have a sense of unity, so that the overall improvement can maximize the efficiency of the installation!
Mainly, the amount of slurry returning to the tower is low, which prevents the slurry components from reaching saturation and thus affects the reaction; however, since the reaction temperature remains stable, the likely reason lies in the slurry circulation rate
The temperature of the gas phase at the bottom of the catalytic distillation tower is high, indicating that a significant amount of heat is generated as a result of reactions. A large difference between the temperature of the gas phase and that of the liquid phase at the bottom of the tower suggests that the liquid level there is low; whereas when the temperatures of the gas phase and the liquid phase are close to each other, the liquid level is high
