The temperature and composition of the gas and liquid phases on the tray are related to each other
Thread Content
During the distillation process, given that there is sufficient vapor in the reactor bottom, is there any relationship between the temperature and composition of the liquid in the reactor bottom, and are there any relationships with the boiling points of the light and heavy components? Is the vapor temperature on the tray related to the vapor composition? Thank you!
During the distillation process, given that there is sufficient vapor in the reactor bottom, is there any relationship between the temperature of the liquid in the reactor bottom and changes in its composition? Answer: There is a relationship; the higher the content of heavy components, the higher the reactor temperature. Is it related to the boiling point of the light and heavy components? Answer: Yes, there is a relationship; the higher the boiling point of a component, the higher the reactor temperature. Is the vapor temperature on the tray related to the vapor composition? Answer: There is a relationship; the higher the boiling point of a component, the greater its content in the Reorganization fraction, and thus the higher the temperature of the gas phase on the tower plates.
Taking a long way around, I would like to ask: if the light and heavy components have different boiling points and their boiling ranges do not overlap, will the liquid in the reactor still contain light components once the temperature in the reactor is raised above the boiling point of the light components?
Yes, as the temperature rises, the pressure increases, which is not conducive to the separation of the components; therefore, some light components will still be present!
