New Approach for Designing an Optimum And Flexible Heat Exchanger Network
Authors
Abstract
It is significant to study and improve the flexibility of chemical plants. The flexibility defined
as the capability to operate this plant over a range of conditions under external disturbances
or inherent uncertainty while satisfying performance specifications by convenient control
variables adjustment. The target of this work is to introduce a new approach for designing
optimal flexible HEN in a similar fashion of multi-period design depending on similar period
durations of worst operating conditions. These worst conditions lie within the uncertainty
range in terms of extreme heat load requirements to decrease number of exhaustive iteration
and enhance flexibility index from the first design step.
