Factors affecting the bottom liquid level in a distillation column
Thread Content
Is the bottom liquid level of the distillation tower related to the reaction temperature? Does the liquid level drop or rise when the reaction temperature is increased? Does the balance agent also affect the bottom liquid level of the tower? Low bottom temperature and rising bottom liquid level?
It also depends on whether there are any changes in the composition of the raw materials. If there are no such changes, and only the reaction temperature is taken into consideration, then it does have an impact: a higher temperature leads to a greater degree of reaction. As the reaction temperature increases, the liquid level should decrease. Many factors need to be taken into account – such as whether to adjust the liquid level at the bottom of the tower If the control valve is fixed and does not adjust, the liquid level should decrease
1. The liquid level at the bottom of the distillation tower is related to the reaction temperature; a higher reaction temperature leads to greater cracking depth, and increasing the temperature results in a decrease in the liquid level. 2. Adding balance agents or fresh materials increases the activity to a certain extent, which in turn leads to greater cracking depth and a decrease in the liquid level as well. 3. As the temperature at the bottom of the distillation tower decreases, the liquid level rises; you will understand why this is the case once you comprehend what the term ‘boiling range’ means
Will the low-temperature equilibrium agent entering the regenerator affect the bed temperature and cause the reaction temperature to drop?
Under normal operating conditions, replenishments to the system are carried out in small quantities and on a frequent basis, so it should have little impact on the system temperature! It is mainly the activity of the catalyst that has a greater impact on the quality of the oil!
There are many factors to consider for the second point. Is the activity of the balance agent higher or lower than that of the catalyst in the system? But it should be more or less the same. A short-term decrease in the regeneration temperature caused by the balance agent leads to an increase in the agent-to-oil ratio as well as a higher degree of reaction; meanwhile, the decrease in regeneration temperature reduces the activity of the system, thereby lowering the degree of reaction. After adding the balance agent, the system’s reserve increases; the regeneration coking time lengthens, and the relatively higher catalyst activity further enhances the reaction depth. . . It depends on the actual situation; it’s important to summarize more during regular operations
It depends on the speed at which you apply the supplement; if it’s applied quickly, that will have an impact. If it’s applied in the same way as with small amounts of additive, then the problem isn’t too serious
