Title: Innovations and Contributions of Shankar Nataraj in Liquid Purification and Energy Management
Introduction
Shankar Nataraj, based in Allentown, PA, is a prominent inventor with a remarkable portfolio consisting of 34 patents. His work primarily focuses on advancements in liquid purification and innovative energy management solutions. Nataraj's inventions showcase a commitment to improving technology and efficiency in industrial processes.
Latest Patents
Among his latest patents, Shankar Nataraj has developed techniques for liquid purification using pressure vessels. In this invention, a system is created where access to at least two pressure vessels is achieved, interconnected through piping and controlled by computer-operated switching valves. The first pressure vessel is filled with liquid, while the second contains pressurized gas, immiscible with the liquid. These valves facilitate the transfer of liquid into a purification chamber using the pressure generated by the gas. Moreover, a third pressure vessel is utilized for simultaneous filling with liquid, ensuring continuous operation and efficiency through prepurification enabled by compressed air. A reverse osmosis chamber further enhances the purification process.
Nataraj has also patented techniques for controlled refrigeration and liquefaction that focus on energy management. This invention involves pumping a liquid into a closed chamber to compress vapor. As pressure increases, vapor assimilates into the liquid, and the heat generated during this process is effectively removed. The liquid, now containing vapor, is withdrawn and flashed to release some of the vapor while absorbing latent heat. Controlling both heating and cooling circuits using liquid pistons optimizes the operations for gas compression and expansion.
Career Highlights
Throughout his career, Shankar Nataraj has contributed to notable companies, including Air Products and Chemicals, Inc. and Energy Internet Corporation. His extensive experience in these organizations underscores his expertise in engineering and innovation.
