Nouryon produces various products in the liquid phase which are supplied to the market as a powder. For many applications our customers require these products to be dry, non-hygroscopic, and free-flowing.
Examples of these products include:
The performance and ease of handling of these materials are highly dependent on the drying process. These drying processes include techniques such as precipitation, crystallization, and spray drying.
Converting a liquid to a powder often involves multiple process steps in order to achieve the desired properties. Final product properties depend on structure, particle size, particle shape, or surface treatment. Given the increasing demand for more advanced product technology, traditional drying techniques no longer provide the complete answer and we need new approaches to keep meeting the needs of our customers.
We are looking to further optimize our drying processes in terms of waste, energy, storage stability of the powder, and sustainability. Irrespective of the drying technique used, final products need to meet certain specification and performance criteria after drying, such as bulk density, particle size distribution, and flowability.
We are looking for solutions that may fit a range of technologies that we can use to make the production of our dry powder range products more efficient. The technology may cover one or more of the folowing aspects: crystalization control, particle size and shape control, or particle hygroscopicity control.
Both process and chemical modification approaches are in scope, provided they are cost-effective. We are looking for both completely new technologies as well as for differentiated common drying technologies.
We are looking for all solutions fitting the scope. Aspects we evaluate the ideas on when selecting for the Imagine Chemistry finals include:
If you think you have an efficient technique for turning our liquids into free-flowing powders, we welcome you to join our Challenge on our Imagine Chemistry Challenge platform for open and collaborative innovation.
