Abstract
A case study is presented, where rigorous process simulation, Pingh
Analysis and HEN design have been used for analysis and design of a heat
exchanger network for a paper mill integrate.The objective is to minimise the
use of external cooling thus minimising the capital expenditure required for a
coolin tower.Two distinct cases, summer and winter, have been studied.Pinch
analysis results indicated that in the winter case no cooling is required and
the selection of hot utilities for covering the heating deficit is not
critical from the cooling demand point of view.For the summer case, however,
hot utilities must be selected more carefully due to high Pinch temperature.
Also some external cooling is required for the summer case.A heat exchanger
network was constructed to demonstrate thet with a practical design it is
possible to get close to the utility consumption targets.Practical constraints
concerning lay-out etc. were taken into account to achieve a design, which
provides a practical target.
