A Flexible Computer Programme for Calculation of Energy and Material Balances in a Sugar Factory

Abstract

A programme system dedicated to the simulation and balancing of energy and material balances in a sugar factory has been developed. Special concern has been put in the development of a flexible and comprehensible user inferface which can be adjusted according to the needs of the individual user. The calculation part of the programme uses a modified version of the sequential modular approach where the calculation path, within the process calculation modules, can be changed. This approach has shown to facilitate the determination of calculation sequence and iteration parameters in the flowsheet. Further, the sugar factory programme includes a method for balancing material balances with redundant plant data and a method for graphical presentation of the flowsheet and calculation results.
