Hoechst Celanese Energy Model
Abstract
The Hoechst Celanese Energy Model is
used for budget preparation and
reconciliation and for ongoing plant
optimization. The model optimizes variable
utilities production costs using a linear
programming approach. Every operating area
provides input to the model for use in
forecasting their utilities demand.
All costs associated with utilities
production are reduced to the costs of
water, fuel gas and electricity. The
various plant balances and restrictions to
operation are applied to the linear
programming in the form of constraint
equations.
Across the plant, equivalent turbines
and motors are available for steam
balancing. Variables have been added to
the program to represent variable steam and
electricity demand. The model converges to
an optimal solution and then selects the
closest match of possible turbine/motor
combinations to this solution. Heuristics
are applied to determine if it is practical
to implement the optimal solution.
