<p>The present invention relates to a process and a device for the separation and purification of gas from a fibre suspension, especially residual gas after ozone delignification or pulp suspension, wherein the suspension together with the gas is introduced into a cyclone (2) or similar in which essential separation of suspension takes place, after which the essentially gas-free suspension is drawn off downwards and the gas (5) containing residual fibre and/or other impurities is drawn off upwards, the gas stream (5), before it is conducted away, being led through a liquid bath for separation of residual fibres and/or other impurities from the gas stream.</p> |
