ANALYSIS AND APPLICATION OF DYNAMIC OPTIM IZATION ALGORITHMS FOR BATCH PROCESSES

Batch processes being increasingly used in the chemical industry. The advantages of batch processes are their flexibility, high product puri ty and the possibility of frequent product changeover. For the economi cal operation of a batch process it is necessary to develop an optimal strategy; therefore a proper optimisation approach is required. For t his reason two different optimisation algorithms, differential dynamic programming and a simultaneous optimisation approach, are investigate d in this paper, The characteristics of the algorithms are worked out and their efficiency is analysed. Simulation results from batch reacto rs and a batch column demonstrate the scope of application of the algo rithms.
