| Summary: | actual process. The resulting model is currently in use by Alcoa's Point Comfort Operations' staff. alterations to the actual plant. This simulator allows for and solid size distributions throughout the precipitation classification system including the determination of particle friendly tool. The interface also allows engineers to view included in the model for adaptation to other facilities. includes useful analysis tools such as a head tank specific Language development package to calculate stream compositions make educated process changes by being able to predict nucleation, or the formation of new growth centers, in of test simulations were also run on the model to determine operation to allow the forecasting of a number of relevant precipitation and classification model in an alumina refining precipitation rate controller and a perfect product removal precipitation vessels with the Advanced Computer Simulation principles and techniques for particle kinetics including process parameters, such as the particle size distribution of properties during simulation. This tool permits engineers to results of changes in operations before transferring the scheme for calculating ideal operating parameters. A variety series of gravity classifiers and updates recycled seed simulating particle growth, collision and agglomeration, and sizes and yields by numerically integrating the unsteady smelting grade alumina production but provisions were solids across the system and the process productivity, or state balance equations for each vessel. This model was The model's input and output interfaces have been developed the qualitative and quantitative accuracy of the model to the the quantitative analysis of the precipitation and This project implements a dynamic alumina hydrate continuous tuned for use at Alcoa's Point Comfort Operations for regular unit. The model also predicts settling characteristics for a using a graphical user interface to provide a more user values as they might appear in lab analyses. This model also yield, using a PC. The model uses basic conservation |
