How to control gasoline. What’s the dry point of diesel? Are there any other methods besides considering the properties of the raw materials?
Normally, it is controlled by adjusting the distillation temperature of the oil, provided that the reflux rate is properly adjusted. A higher distillation temperature corresponds to a higher dry point; generally, one degree change in temperature corresponds to one degree change in the dry point.
If the drying temperature is too low, shouldn’t the temperature at the bottom of the tower be increased?
It is not necessary to mention the temperature at the bottom of the tower; mentioning the temperature in the middle section is also acceptable, as long as the heat and mass balance within the tower is maintained.
It should be in your operating procedures.
Generally, it is the temperature at the top and middle of the tower that is controlled, with the pressure at the top of the tower also having an impact
