Abstract
Optimization of individual processing
units as well as the energy systems has become
common place in the processing industries
(Ref. 1,2). Typically such optimizations are
done piecemeal, with heavy reliance on the
'transfer prices' to link the various
optimizations. Such optimizations usually
lead to decision policies which are inferior.
Superior results are obtained when the
processing units and the plant energy system
are optimized jointly, in which case the
'transfer prices' become superfluous.
A MILP (Mixed Integer Linear Programming)
based approach for plant wide optimization is
presented. This approach has been
successfully applied in Union Carbide, and
this paper describes a specific application at
one plant.
