Aurora, Colorado Patent of the Year – 2024/2025
West Edison Inc. has been awarded the 2024/2025 Patent of the Year for its innovative crystal purification technology. Their invention, detailed in U.S. Patent No. 11931702, titled ‘Apparatus for purifying crystals using solvent vapors’, introduces a Reflux Rinsing apparatus that purifies crystals using solvent vapor through dynamic equilibrium recrystallization.
This apparatus features a pressure vessel containing a liquefied gas solvent and impure crystalline material. By heating the vessel’s lower portion, solvent vapors are generated, initiating a reflux rinsing process that removes impurities from the crystal surfaces. The system includes mechanisms to apply pressure, control heating duration, and adjust the vessel’s angle, enhancing purification efficiency. After the process, the solvent is reclaimed, leaving behind purified crystals and separated impurities.
This technology offers a streamlined approach to crystal purification, potentially benefiting industries requiring high-purity crystalline substances. By integrating pressure control, timed heating, and adjustable vessel orientation, the apparatus ensures consistent and efficient purification outcomes.
West Edison, Inc.’s innovation represents a significant advancement in crystallization technology, providing a practical solution for producing high-purity crystals. As industries continue to demand refined materials, such apparatuses will play a crucial role in meeting quality standards and production efficiency.
