Zero Effluent Scheduling Model

The following sets, variables and parameters constitute the mathematical formulation for the nature of the problem presented in this chapter. 

It is first necessary to define the problem that is addressed in the formulation, as given in the following section.

The synthesis model is based on the zero effluent scheduling formulation with the addition of design specific constraints. The scheduling constraints used in the synthesis formulation are identical to those used in the scheduling formulation and the mass balance constraints are virtually identical except for a few minor changes in the limiting capacities, amount of water and amount of product. These changes will be discussed below.
