Connection involving Segments The side stream in the downcomer of an active segment to the adjacent segment The side stream in the downcomer of an active segment to the adjacent segment is is integrated inside the material and energy balance (see Figure two).

The flow from and to adjacent cent segments is assumed, related for the strategy from the preceding section, on the basis segments is assumed, related to the method from the earlier section, around the basis of of Torricelli’s law, thereby, thinking of the height from the liquid within the person downTorricelli’s law, thereby, taking into consideration the height on the liquid in the individual downcomer. comer.

Structure of the segmented column model. Figure three. Structure in the segmented column model.As is often noticed, the model has an analogous layout for every segment. Every single segment As is usually noticed, the model has an analogous layout for every single segment. Each segment consists of an individual condenser, trays with radial flow, a reflux drum as well as a reboiler, and consists of a person condenser, trays with radial flow, a reflux drum and a reboiler, is controlled by a PI controller within a inside a standard LV-configuration [41]. The adjacent segand is controlled by a PI controller normal LV-configuration [41]. The adjacent segments are interconnected across all stages, except for the very first first stage. It can be assumed the the ments are interconnected across all stages, except for thestage. It is assumed that thatfirst stage has has no downcomer. initially stage no downcomer.
