A device () for separating sulphur dioxide from a gas () by means of an absorption liquid has an inlet () for gas () containing sulphur dioxide, an outlet () for gas (), from which sulphur dioxide has been separated, and as essentially horizontal apertured plate (), which is arranged to allow passage from below of sulphur dioxide containing gas () and to carry, on its upper side (), a flowing layer () of the absorption liquid. An outlet box () beside the apertured plate () is arranged to be passed by liquid, which is distributed in the gas () coming from the inlet (). A first pumping means is arranged to feed a coolant flow to the outlet box () and a second pumping means is arranged to feed an absorption liquid flow, which is essentially independent of the coolant flow, to the apertured plate () to form the flowing layer (). In a method of separating sulphur dioxide, the above-described device () can be used.

Method and device for separating sulphur dioxide from a gas

A device () for separating sulphur dioxide from a gas has an inlet () for the gas () and an outlet () for gas (), from which sulphur dioxide has been separated. An apertured plate () is arranged between the inlet () and the outlet () and allows the gas () to pass from below. On its upper side (), the apertured plate supports a flowing layer () of absorption liquid. An inlet duct () connects a container () for absorption liquid to the upper side () of the apertured plate (). A means () conveys the absorption liquid () from the container (), through the inlet duct (), to the upper side () of the apertured plate () and along the apertured plate (). The device also has an outlet box () for collecting the absorption liquid () flowing over the apertured plate () and at least one distribution means (), which is arranged to contact the gas () which is supplied to the device () through the inlet () with the liquid () flowing from the outlet box () to the container () before the gas () passes through the apertured plate ().
