IMPLEMENTATION OF NOVEL PROCESSES IN EXISTING PROCESS NETWORKS - EVALUATION OF THE INDUSTRIAL-PRODUCTION OF C-4 CHEMICALS BY OPTIMIZATION

An analysis method of optimal network flexibility was developed and im plemented in MATLAB. The use of novel processes in the existing Dutch C-4-network was assessed. Since its optimal structure is determined by only two processes, development of these must be given priority. The network has substantial flexibility with respect to total mass use, bu t almost none when total energy usage is considered. Some novel proces s therefore may not be implemented if profits are largely determined b y total cost of feedstock.
