Title: Innovations of David H Ying
Introduction
David H Ying is a notable inventor based in Macungie, PA (US). He has made significant contributions to the field of gas separation technologies, holding a total of 4 patents. His work focuses on innovative processes that enhance efficiency in various industrial applications.
Latest Patents
One of his latest patents is titled "Hybrid membrane - cryogenic generation of argon concurrently with." This invention involves an efficient process for separating selected components of a gas stream by integrating a cryogenic separation unit and a membrane separation unit. The system allows for the concurrent generation of an argon-rich stream, along with a nitrogen-rich product stream, from a gas stream typically comprising oxygen, nitrogen, and argon, such as air. The novel system uses a membrane to preferentially reject the oxygen component, thereby accumulating the argon component for separation as an argon-enriched product stream.
Another significant patent is the "Fired heater for coal liquefaction process." This invention is designed to operate under conditions that maximize the slurry slug frequency, improving heat transfer efficiency. The controlled operating conditions include pipe diameter and arrangement, minimum coal/solvent slurry velocity, maximum gas superficial velocity, and the volumetric flow velocity ratio of gas to coal/solvent slurry.
