Hun har bedt om at foredraget blir tirsdag formiddag. THE USE OF THE ATTAINABLE REGION TO SYNTHESISE OPTIMAL COCURRENT = MULTIPHASE REACTORS Craig McGregor, Diane Hildebrandt* and David Glasser School of Process and Materials Engineering, University of the Witwatersrand, Private Bag 3, WITS 2050, South Africa, dihil@chemeng.chmt.wits.ac.za Abstract The geometric ideas of Attainable Region analysis are extended to consider mass transfer in addition to the usual fundamental processes of reaction and mixing in units with cocurrent flow. Optimal steady-state processes can then be synthesised that use these fundamental processes. In particular, systems are examined with two phases flowing into and out of the process. The reaction is assumed to occur in one phase only and the separation assumes either a semi-permeable membrane or transport across the interface between two different phases. This model allows novel reactors such as membrane reactors, trickle-bed reactors and slurry-bed reactors to be considered for the reactor network. The method is illustrated using two simple examples that demonstrate that quite complicated processes layouts can be obtained.
