Program for · Simulating and Evaluating a Continuous a - Sugar Pan

The Continuously Operating Raw Pan Simulation and Evaluation (CORPSE) is a steady-state computerised simulation of such a pan, based on the solution by the Newton-Raphson method of simultaneous algebraic equations which describe the mass and heat transfer within and the material balances over each compartment. Each compartment is considered as a stirred tank reactor, with unknown components being: Total solids, total sucrose, crystal sucrose and water. Other unknowns could include compartment volumes and process values such as pan vapour pressure, supersaturation and mass and heat transfer coefficients. The user of the model has considerable freedom of choice of input data. . This model has been used for: • Evaluating process parameters from observations of an operating pan. If more than the minimum amount of data is submitted, the program performs a least-squares fit. • Sizing of compartments and calandria heat transfer areas for design purposes. • Showing how different values of controllable process variables affect the operation of the pan.
