What are supercritical fluid processes principles and practices ?
A fluid become supercritical when both its temperature and pressure exceed the “Critical point’’. In this state the fluid has specific properties. Supercritical fluids are used as alternative solvent to improve processes as extraction, impregnation, particle formation, formulation, sterilization, cleaning and chemical reactions.
This method is definitely green since it uses eco-resources and generates a co-product rather than waste.
