Latest Patents

Zhihong Dang holds a patent for a "Fluidized bed separation method and device for methanol-to-olefins quenched water." This patent describes 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, effectively 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.
