Dynamics of processes with significant energy recovery

2 Dynamics of processes with significant energy recovery 

Assuming that individual process units are modeled as lumped-parameter systems and that kinetic and potential energy contributions are negligible, the 

Let us now concentrate on the energy dynamics of the system (6.3), for which we make the following steady-state assumptions. 

Assumption 6.1. The internal energy flow rates HitS, i = 1. N — 1, are of similar magnitudes (i.e., li = Hi s/H s = 0(1)) and much larger than the inlet and outlet energy flows Hqs and 11 n,h, that is 

Assumption 6.3. The magnitude of the energy flow rate Q-m = Qout is similar to the magnitude of the energy flows H, i = 1,. .., N — 1, and we have
