A process for treating bitumen froth with paraffinic solvent is provided which uses three stages of separation. Said extinction gas flow is coaxially surrounded by a flow guide device one surface area of which is provided with at least one discharge opening for deflecting at least a part of the extinction gas flow towards a discharge direction, said discharge direction being oriented tangential and substantially at an angle to the axial direction. The frame alerts the observer to a hazard. Fasteners and panels can be added to each configuration to provide further protection to the underlying factor car seat cover. This is especially advantageous when using low pin count IC devices.
