Abstract
A PC based simulator of the steady-state behaviour of multiple-effect calandria (or equivalent) evaporators is presented. The package, ‘MULTEVA’ can be applied in studies concerning thermodynamic design, in the analysis of alternative forms of operation and in the monitoring of unit efficiency. The latter is achieved through an option which performs the estimation of the heat transfer coefficients for given operation data. Three types of feed configurations are allowed, viz. - forward, mixed and backward. Up to 20 effects are accepted for analysis in each configuration. A database on the relevant thermodynamical and physical properties of the solute, solvent and solution has been created with read/write capacities. The simulator derives from the database all the necessary information to carry out the computations. The general model employed is based on theoretical heat and mass balances and on equilibrium considerations. It has already proved its efficiency in industrial applications of sugar liquor evaporation.
