Synthesis of Inter-Plant Water Networks Involving Batch and Continuous Processes

摘要

This work presents a mathematical technique for the synthesis of inter-plant waterrnnetworks, where some of the plants involve batch and continuous processes. Tornintegrate both kinds of process units, a two-phase approach is proposed. First, all batchrnunits are treated as operating in continuous mode, and the inter-plant water network isrnsynthesized for minimum fresh water consumption. Policy of water storage for the batchrnunits is then determined, on which they can behave as continuous units. The objectivernof the second phase is to minimize the capacity of storage tanks subject to therndetermined water flow rates. An example is solved to illustrate the proposed approach.
