Title: Innovations by Inventor Raymond Shih
Introduction
Raymond Shih is a notable inventor based in Elgin, IL (US). He has made significant contributions to the field of polymer recycling and processing. With a total of 7 patents to his name, his work focuses on innovative methods for treating and conditioning polymer materials.
Latest Patents
One of his latest patents is titled "Solvent based approach to post-consumer recycling of polyethylene terephthalate." This process involves treating a feed of polyethylene terephthalate by dissolving it in a polar solvent at temperatures ranging from about 100 to 250°C. The method includes adding an anti-solvent that is less polar than the initial solvent, followed by cooling the mixture to precipitate purified polyethylene terephthalate. The solid purified polyethylene terephthalate is then separated from the remaining liquids.
Another significant patent is "Processes and apparatuses for conditioning polymer particles for an SSP reactor." This invention outlines processes and apparatuses designed to produce polymer particles using a solid state polycondensation reactor and an underwater pelletization unit. The apparatuses feature a pre-conditioning zone that adjusts the temperature, crystallization, and content of dust, acetaldehyde, and water in the particles. Various inert gas streams can be utilized to remove impurities and optimize the conditions for the particles entering the SSP reactor.
