Process Systems Enterprise has announced that it has launched its gCRYSTAL product. The product provides a drag and drop interface for users to innovate, engineer and optimise the crystallisation process. This package is intended to be used by process engineers and scientists in areas where the crystallisation process is required.
gCRYSTAL is designed to provide models based on population balance. These models contain representations of each crystallisation process in the fields of physics and chemistry. The models are then evaluated based on data derived from stable and dynamic experiments. The models, which fulfil all the criteria are used to optimize the design and operate the crystallisation process and assess and manage risks arising from engineering decisions. They are also used to assess the economics of both a continuous and batch crystallisation process.
Crystallisation processes are usually difficult to implement on a large industrial scale due to the lack of proper modelling techniques. Modelling tools like gCRYSTAL help in the smooth transition of the crystallisation process from the laboratory level to the factory level. Use of such techniques result in high savings in energy and deliver consistent and reliable outputs said Bermingham. Friesland Campina was able to reduce its batch time by 44% after optimizing a cooling crystallisation process to produce its pharmaceutical grade lactose. gCRYSTAL has also been integrated with PSE’s product gSOLIDS for the optimisation of the incorporated vapour to liquid to solid process.
