Title: Ligong Qiao: Innovator in Fluidized Bed Separation Technology
Introduction
Ligong Qiao is a notable inventor based in Guangdong, China. He has made significant contributions to the field of chemical engineering, particularly in the area of fluidized bed separation methods. His innovative approach has the potential to enhance the efficiency of methanol-to-olefins processes.
Latest Patents
Ligong Qiao holds a patent for a "Fluidized bed separation method and device for methanol-to-olefins quenched water." This patent discloses a method that subjects quenched water to liquid-solid separation using a micro-cyclone separator. The clear liquid obtained from this process undergoes a secondary separation via a fluidized bed separator, which is then directed to an olefin separation device. The method also includes recovering waste heat from the quenched water and returning it to a quenching tower after heat exchange. Additionally, it regenerates a separation medium by feeding purified water or quenched water back into the system, releasing catalyst particles absorbed by the separation medium. The concentrated catalyst slurry is then sent to a filter-press unit for dehydration, allowing for catalyst recovery.
