For simultaneous heat integration of continuous processes we had used a modified model, developed by Duran and Grossmann (1986): Allow the determination of minimum utility consumption (cost) in an optimal process scheme Basic model is based on a pinch point location method for the consumption of hot and cold utilities in the nonlinear optimization problem We have modified basic nonlinear model to linear model: Have a constant temperature process streams Heat capacity of hot and cold process stream flows are variable Avoid nonconvexity and model can obtain global optimal solutions Aggregated mathematical model
