R. Grau et al., GLOBAL STRATEGY FOR ENERGY AND WASTE ANALYSIS IN SCHEDULING AND PLANNING OF MULTIPRODUCT BATCH CHEMICAL PROCESSES, Computers & chemical engineering, 20(6-7), 1996, pp. 853-868
Energy integration and waste minimization have received increasing att
ention in the chemical industry. Recent studies have addressed the spe
cific problems that arise in batch chemical processes. However, a prod
uction plan built up using schedules developed beforehand may become i
nefficient or even fail to attain its production targets. Furthermore,
production plans satisfying demand objectives may reduce or even elim
inate energy integration or waste minimization opportunities. In this
work, waste and energy minimization are treated as an integral part of
the constrained production scheduling problem with limited resources.
The methodology developed is based on a comprehensive and rigorous mo
delling framework used to describe the detailed batch process operatio
ns as a preliminary step rewards their optimization. The methodology w
ill be presented and results from case studies will be provided to ill
ustrate the complex interaction between energy integration, waste mini
mization and production planning in multiproduct batch processes.
