| Abstract Scope |
Crystallisation is an important unit operation in industrial settings for raw product formation, purification and waste removal. This process typically requires multiple processing steps (crystallisation, solid liquid separation and product drying) to attain the final product. Here, we introduce a novel process: membrane percrystallisation which achieves complete separation of solvent from solute in a single step. Liquid is vaporised at the inorganic membrane permeate surface, whilst dry solid product is continuously ejected from the permeate surface, under vacuum. This novel technology has been demonstrated in metal recovery and waste brine treatment applications. In summary, membrane percrystallisation is a new form of crystallisation process intensification which offers a simple, compact and closed system. Within this study, key percrystallisation operating parameters in salt crystallisation that employ supported continuous saccharides carbon membranes will be discussed with examples of potential applications in hydrometallurgical processes. |
