Title: The Innovations of John E Thelen
Introduction
John E Thelen is a notable inventor based in Ocala, Florida, with a remarkable portfolio of eight patents. His work primarily focuses on advancements in gas fractionation and adsorbent technologies. Thelen's innovative contributions have significantly impacted the field of gas processing and separation.
Latest Patents
Among his latest patents is the "Heat Reactivated Adsorbent Gas Fractionator and Process." This system is designed for regenerating an adsorbent in an off-line adsorption chamber. It includes a heat exchanger that exchanges heat from a first fluid coming from a compressor and a second fluid. Notably, only a portion of the first fluid flows through the heat exchanger when it is in gas form. The system also features a conduit that provides fluid communication between the second fluid exiting the exchanger and the off-line adsorption chamber, which contains the adsorbent. Additionally, there is an outlet configured to release the second fluid from the off-line adsorption chamber.
Another significant patent is the "Adsorbent Fractionator Directional Flow Control Valve Assembly Apparatus and Method." This assembly includes two inlet check poppet valves, two outlet check poppet valves, and a valve body. The assembly effectively controls the directional flow of an influent gas mixture into one of two vertical desiccant tanks of an adsorbent fractionator, or desiccant dryer. The valve body is a single unitary piece that couples the inlet and outlet check poppet valves, providing flow communication between these components and the respective ports.
