Utilities and Integrated Biorefineries s One power plant for all processes: centralized utilities
Background image of page 12
Utilities and Integrated Biorefineries s Overhead is minimized s Utilities can be produced and distributed to each process s Therefore, it is more profitable!

Narrowing it down s Mathematical Model s Objective: Maximize the Net Present Value s Eliminate processes/products that are the least profitable s Select the most profitable processes and their corresponding capacities and production rates throughout the project lifetime
Background image of page 16
Mathematical Model s Net Present Value: ( 29 df cash(t) = t NPV The Net Present Worth (NPW) is “the total of the present worth of all cash flows minus the present worth of all capital investments.”
