A device (1) for separating sulphur dioxide from a gas (4) by means of a flowing layer (414) of an aqueous absorption liquid (36) passing horizontally over an apertured plate (8) from an inlet zone (78) to an outlet zone (480) for the purpose of separating sulphur dioxide from the gas (4) which passes through the flowing layer (414), characterised in controlling the thickness of the layer (414) of absorption liquid by at least one of the following two measures: i) adjusting the thickness of the layer (414) of absorption liquid by adjusting a throttle valve (492) being arranged in the outlet zone (480), and/or ii) deflecting, by means of a guide rail (592) arranged in the inlet zone (578), absorption liquid flow supplied to the inlet zone (578) from a vertical flow (AF) direction to a horizontal flow (AL) direction. In a method of separating sulphur dioxide, the above-described device (1) can be used. |
