This project has developed systematic methods for the design and optimisation of crystallisation operations. Project Description Crystallisation involves formation of a solid product from a liquid solution. The design of crystalliser for a given separation depends on the method used to bring about supersaturation. Batch, semi-batch and continuous crystallisers can be used. Modeling crystallisation must account for nucleus formation through primary and secondary mechanisms and crystal growth around the nucleus.
Secondary mechanisms depend on agitation and mixing and seeding through the addition of crystals.
The size of the crystals and the size distribution of the final crystals are both important in determining the quality of the product. When optimising crystallisation there are many important degrees of freedom to be optimised to obtain the best design. This project has developed methods by which these degrees of freedom can be optimised simultaneously for crystal quality.
