gCRYSTAL

Features

gCRYSTAL's powerful, comprehensive and easy-to-use capabilities are built on the following key features:

A library of common crystalliser configurations for single or multi-stage batch, semi-batch and continuous operations, including different supersaturation options and seeded and unseeded operation
Drag-and-drop flowsheeting for creating process flowsheets.
Dynamic simulation capabilities for modelling start-up, grade-change and other transient operations
Dynamics and graphical scheduling for batch and semi-continuous processes
Downstream integration with gSOLIDS and upstream integration with liquid and gas models for simultaneous design and optimisation of crystallisation and solids processes.
A stream structure that includes crystal size distributions and chemical compositions, making it possible to predict the evolution of the crystal size distribution resulting from nucleation, growth, agglomeration and attrition.
Parameter estimation facilities for fitting models to experimental or operating data in order to provide an accurate predictive capability.
Dynamic and mixed-integer optimisation capabilities, for optimisation of flowsheet and equipment design taking into account many decision variables simultaneously.
Links to CFD, for consideration of hydrodynamic effects, for example, in scale-up studies or when studying changes to crystalliser configuration.
