CYCLONIC SEPARATION ASSEMBLY HAVING LOW RESIDENCE TIME PLENUM ARRANGED IN FLUIDIZED BED REACTOR VESSEL Russian patent published in 2019 - IPC B01J8/00 B04C5/24 

FIELD: technological processes.

SUBSTANCE: invention relates to a cyclone reactor vessel having a low residence time plenum. Said vessel includes a shell, a primary cyclonic separation device located inside the shell and having an outlet, a plurality of secondary cyclones, wherein said secondary cyclones are located inside the shell, and each of the secondary cyclones has a body, an inlet and an outlet, wherein the outlet of the primary cyclonic separation device is connected to the inlet of the secondary cyclone such that a fluid stream may flow from the outlet of the primary cyclonic separation device into the inlet of the secondary cyclone, a first plenum having a skirt and a floor forming a sealed annular chamber within the shell, wherein the first plenum is supported within the shell by attachment to the shell, a second plenum having an outlet tube for removing gasses from within the shell, a skirt and a floor and having a smaller volume than a volume of the first plenum, and a secondary cyclone support system that minimizes or prevents mechanical thermal stresses, wherein the outlets of a plurality of secondary cyclones are in fluid connection with the second plenum.

EFFECT: invention provides a reduction in the residence time of molecules at the reaction temperature.
