description | A system and method for solvent recovery in a batch fluidized bed process is provided. The disclosed fluidized bed system includes a fluidized bed vessel holding a batch of solvent-containing product; an intake circuit supplying an inert fluidizing gas; an effluent circuit adapted to remove the solvent containing inert fluidizing gas; a first recycle circuit coupling the effluent circuit to a solvent recovery means; a second recycle circuit directly coupling the effluent circuit to the intake circuit and a flow control valve operatively disposed to divide the effluent between the first recycle circuit and the second recycle circuit based on the operating regime of the fluidized bed process. The disclosed embodiments further include a liquid nitrogen source coupled to the second recycle circuit to provide the make-up inert gas and enhanced cooling of the effluent based on the operating regime of the fluidized bed process. |
