SERIES-COUPLED FLUIDIZED BED REACTOR UNITS INCLUDING CYCLONIC PLENUM ASSEMBLIES AND RELATED METHODS OF HYDROFLUORINATION

摘要

Embodiments of a series-coupled fluidized bed reactor unit (10) are provided. In one embodiment, the reactor unit includes primary and secondary reactors (12, 14). The primary reactor includes a reaction vessel (16), a gas distributor (20) fluidly coupled to the reaction vessel, and a cyclonic plenum assembly (22). The cyclonic plenum assembly includes a plenum assembly housing (70), which has an annular sidewall (74); and a gas/solids inlet pipe (72), which fluidly couples a partially-reacted gas outlet of the secondary reactor to the plenum assembly housing. The gas/solids inlet pipe is tangentially positioned with respect to the annular sidewall of the plenum assembly housing to induce vortex flow within the plenum assembly housing of the partially-reacted gas received from the secondary fluidized bed reactor through the gas/solids inlet pipe to promote the cyclonic separation of entrained solids from the partially-reacted gas prior to entry into the gas distributor.
