Modeling the energy consumption of chemical batch

A top-down approach was used to investigate, whether or not it is possible to correlate the overall energy/utility consumption with the total amount of chemicals produced in a chemical batch plant. This approach was suitable for monoproduct batch plants but not for multiproduct and for multipurpose batch plants that produce a large variety of ...
