Abstract:
A system and method for solvent recovery in a batch fluidized bed process is provided. The disclosed embodiment of the fluidized bed system includes a fluidized bed vessel adapted to contain a batch of solvent-containing product; an influent or intake circuit adapted to supply an inert fluidizing gas to the fluidized bed vessel; an effluent circuit adapted to remove the solvent containing inert fluidizing gas from the fluidized bed vessel; 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 source of liquid nitrogen coupled to the second recycle circuit to provide the make-up inert gas as well as provide enhanced cooling of the effluent based on the operating regime of the fluidized bed process.
