Abstract: PURPOSE: A separation and concentration device for fluorinated gas and a separation and concentration method for fluorinated gas using the same are provided to achieve the high separation and concentration efficiency of fluorinated gas compared to the previous pressurizing method which processes fluorinated gas using a separation film and to maintain the constant pressure of a separation film module in which the separation of fluorinated gas is conducted, thereby preventing efficiency reduction due to a large size and preventing an adverse effect to a fluorinated gas discharge process due to a pressurizer. CONSTITUTION: A separation and concentration device for fluorinated gas comprises a gas supply unit(100), an inflow control unit(200), a separation unit(300), a pressure reducer(400), and a discharge quantity control unit(500). The inflow control unit controls the flow rate of mixed gas including fluorinated gas supplied from the gas supply unit. A separation film module comprises an inlet, a penetration part, and an outlet. The mixed gas is injected into the inlet through the inflow control unit. Non-fluorinated gas in which the fluorinated gas is separated is discharged through the penetration part. The separated fluorinated gas is discharged through the outlet. At least one separation film module which separates the fluorinated gas from the mixed gas is serially connected to the separation unit. The pressure reducer is connected to the penetration part of the separation unit. The pressure reducer reduces the pressure inside the separation unit and generates driving force by which gas is injected into the separation film module and separated. The discharge quantity control unit is connected to the outlet of the separation unit in order to control the flow rate of the fluorinated gas discharged from the separation unit.
