Latest Patents

One of Parimal Paul's latest patents is titled "Selective extraction of potassium chloride employing tartaric acid as safe, benign and recyclable extractant." This invention addresses the challenges associated with the recovery of potassium chloride from schoenite end liquor (SEL) using traditional extractants, which often pose safety hazards. His method utilizes the bitartrate ion, particularly L-bitartrate, to efficiently precipitate potassium bitartrate from SEL, achieving approximately 90% utilization of the extractant. This process not only enhances the recovery of potassium chloride but also demonstrates the recyclability of the extractant, significantly reducing waste.

Another significant patent focuses on a simpler and more energy-efficient process for the preparation of fatty acid methyl ester (biodiesel) from sun-dried whole seed capsules. This invention eliminates the need for excess methanol recovery through distillation and introduces cost-effective resin treatment for refining methyl ester. Additionally, it utilizes co-streams for the preparation of high-density energy briquettes and biodegradable polymers, showcasing a comprehensive approach to sustainable energy production.
