Abstract.
The paper discusses optimal operation of a general heat exchanger
network with given structure, heat exchanger areas and stream data
including predefined disturbances. A method that combines the use of
steady state optimization and decentralized feedback control is
proposed. A general steady state model is developed, which is easily
adapted to any heat exchanger network. Using this model periodically
for optimization, the operating conditions that minimize utility cost
are found. Setpoints are constant from one optimization to the next,
and special attention is paid to the selection of measurements such
that the utility cost is minimized in the presence of disturbances and
model errors. In addition to heat exchanger networks, the proposed
method may also be applied to other processes where the optimum lies
at the intersection of constraints.
Note: This version may be slightly different from the finally published journal paper.
