A method for enrichment of a mixture of graphene nanoplatelets (GNPs) in provided. The method may include providing GNPs. The method may further include introducing the GNPs into a separation column to separate the GNPs into fractions that may be based on lateral particle size range which may result in separated GNPs. The method may also include collecting the separated GNPs with desired sizes.

A dry fractionation method and system provides for generating a protein concentrate product therefrom. The method and system includes milling a plant-based flour to generate milled flour and generating a first protein concentrate from the milled flour using an air classifier. The method and system includes processing the first protein concentrate to generate a protein rich curd and generating a neutral hydrolyzed protein slurry by mixing the protein curd with a base, water and enzymatic cocktail. The method and system includes generating a homogenized protein slurry from the protein slurry and generating a cooled protein slurry by pasteurizing the homogenized protein slurry. Therein, the method and system provides for extracting the protein concentrate product from the cooled protein slurry.

A method of providing highly reactive hydrated lime and the resultant lime hydrate where an initial lime feed comprising calcium and impurities is first ground to a particle-size distribution with relatively coarse particles. Smaller particles are then removed from this ground lime and the smaller particles are hydrated, allowed to mature in a damp state, and flash dried to form a hydrated lime, which is then milled to a significantly smaller particle size than that of the relatively coarse particles.
