Pinch methodology was applied to the heat exchangers network (HEN) synthesis
of nitric acid production. The integration is analyzed in two ways, and the
results are presented as two different solutions: (i) the first solution is
based on the original heat transfer equipment arrangement, (ii) in order to
eliminate the shortages of the first solution the second HEN was obtained
using process simulation with optimized process parameters. Optimized HEN,
with new arrangement of heat exchangers, gave good results in energy and
process optimization.
