Title:
FLUIDIZED BED SEPARATION METHOD AND DEVICE FOR METHANOL-TO-OLEFINS QUENCHED WATER
Document Type and Number:
WIPO Patent Application WO/2022/056776
Kind Code:
A1
Abstract:
Disclosed are a fluidized bed separation method and device for methanol-to-olefins quenched water. The fluidized bed separation method for methanol-to-olefins quenched water comprises the following steps: (a) subjecting quenched water to liquid-solid separation via a micro-cyclone separator, so as to eliminate large particles entrained in the quenched water; (b) subjecting clear liquid from the micro-cyclone separator to a secondary separation via a fluidized bed separator to remove the residual particles in the quenched water, then sending same to an olefin separation device to serve as a low-temperature heat source, recovering some waste heat of the quenched water, and then returning same to a quenching tower after performing heat exchange; (c) after continuously operating the fluidized bed separator for a period of time, regenerating a separation medium by means of reversely feeding stripping tower purified water or quenched water, so as to release catalyst particles absorbed by the separation medium; and (d) sending a catalyst slurry concentrated by the micro-cyclone separator and the fluidized bed separator to a filter-press unit for filter-press dehydration, so as to recover a catalyst. Also disclosed is a fluidized bed separation device for methanol-to-olefins quenched water.
