Node and Process

The mass balance equations around a node, where there are n input flows and o output flows:

The component mass balance equations for a balance around a node are as follows for all components i:

A state balance for each of each flow j, input, and output is generated and takes this form:

Where:

Inputj \= mass flow of jth input

xj,i \= fraction of component i in jth input or output

Outputj \= mass flow of jth output

N = number of components
