What happens if the normal bottom injection steam volume is too high or too low?
When an excessive amount of steam is introduced at the bottom, it increases the volume of steam rising inside the tower, which can cause the gas flow velocity within the tower to exceed the specified value and lead to tower flooding. This also increases the load on the top of the tower as well as on the condenser at the tower top. If the superheated steam volume is too low, the extraction yield at atmospheric pressure will be low; when the temperatures in the various side streams remain constant, the composition of the product will be leaner.
