Cost-Effective Bypass Design of Highly Controllable Heat-Exchanger Networks

( ) Design of a cost-effecti®e and highly controllable heat-exchanger network HEN has drawn a great deal of attention for years. One of the key issues in such a design is how to effecti®ely minimize undesirable disturbance propagation in a network with minimum cost increment. Design options in this regard include the deri®ation of a superior network structure and the selection of bypasses assoc...

Control structure design for optimal operation of heat exchanger networks

When only single bypasses and utility duties are used as manipulations, optimal operation of heat exchanger networks (HENs) can be categorized as an active constraint control problem. This work suggests a simple split-range control scheme to implement the optimal operation. The control structure can be found by solving an integer-linear programming (ILP) problem with two objective functions pro...

debottlenecking of heat exchanger networks with fixed pressure drops (ii) design.

debottlenecking of heat exchanger networks is a very important issue, when a plant is subject to process changes and/or increased throughput. in previous paper, a new targetting method was introduced, that allowed the designer to consider hydrodynamic constraints when debottlenecking a network. in this paper, a design procedure, which guarantees the consistency of the results of targetting stag...
