Latest Patents

One of her latest patents involves the membrane separation of hydrocarbons using cycloparaffinic solvents. This process allows for the effective separation of heavy crude oils, which often contain metal contaminants such as nickel, vanadium, and iron. By passing a solution of crude oil dissolved in a cycloparaffinic hydrocarbon solvent through a polymeric membrane, lighter hydrocarbon oils can be recovered as the permeate, while heavier oils and contaminants remain as the retentate.

Another notable patent focuses on the separation of a monosaccharide from an aqueous solution containing both monosaccharides and polysaccharides. This innovative process utilizes mixed matrix membranes, which consist of adsorbent or molecular sieve materials dispersed in an organic polymer. The design allows for the selective passage of monosaccharides, which have a greater steady-state permeability compared to polysaccharides, facilitating their recovery.
