System description and modeling

Considering that the individual process units are modeled as lumped-parameter systems, the mathematical model that describes the overall and component material balances of the process has the generic form 

The premises that we rely upon in the analysis presented in this chapter draw on Assumptions 4.1-4.4 and the discussion in Section 3.2, and are summarized below. 

Assumption 5.1. There are no significant side-streams in the process. Consequently, the nominal flow rates of the streams in the recycle loop are of comparable 

Assumption 5.2. The net rates at which the components 1. C — 1 are separated from the recycle loop, as well as the nominal flow rate of the product stream, are of comparable magnitude. Also, from mass-balance considerations, they are of the same magnitude as the flow rate of the process feed stream
