Title: The Innovations of Xiangmin Li: Pioneering Propylene Oxide Separation Systems

Introduction: Xiangmin Li is an inventive engineer based in Glen Mills, PA, whose contributions to the field of chemical engineering are exemplified through his impressive portfolio of nine patents. His innovative work primarily focuses on optimizing alkylene oxide separation systems, which are vital for efficiently processing chemical compounds in industrial applications.

Latest Patents: One of Xiangmin Li's latest patents has revolutionized the method of propylene oxide separation. His invention encompasses a sophisticated separation system consisting of a distillation column, a decanter, and a water wash system. The distillation column is designed to process a crude propylene oxide stream, effectively discharging an impurity stream containing methanol and water, and producing a bottoms stream that retains the majority of the propylene oxide. The decanter plays a crucial role by receiving the impurity stream along with a hydrocarbon solvent, allowing for the formation of an organic phase and an aqueous phase. The organic phase, rich in propylene oxide, is directed back to the distillation column, while the aqueous phase is primarily comprised of methanol and water, which is subsequently purged via the water wash system. This innovative method enhances the separation process and improves overall efficiency in propylene oxide production.
