Figure 2.2 gives an overview of the proposed approach. First, a statistical analysis is carried out for the composition data. Several feeds are chosen, and process simulations are performed using a set of given assumptions to meet product specifications. Then, a process design is developed for each feed. Next, fixed and variable costs are estimated using simulation results, which include equipment sizing, mass and energy balances, operating conditions, and utility consumption as well as detailed cost data. Finally economic calculations are performed, and when combined with revenue information enable analysis of economic results.
