Demister, method of modifying an existing wet-type gas scrubber and wet-type gas scrubber

A demister configured for installation to a wet-type gas scrubber which comprises a wet-scrubbing phase and a liquid separation phase, said liquid separation phase including a liquid collecting tank and a cyclonic droplet separation tower attached on the liquid collecting tank for receiving a gas stream therefrom, said demister comprising a tubular frame containing a mist eliminator unit for removal of liquid droplets from a gas stream, characterized in that the demister is a separate integral unit adapted to be removably attachable between the liquid collecting tank and the cyclonic droplet separation tower, where the frame comprises:

• a tubular outer wall having an inner diameter which substantially equals the inner diameter of the cyclonic droplet separation tower, and
• a tubular inner wall having an outer diameter which is smaller than the inner diameter of the outer wall, said inner wall being disposed coaxially inside the outer wall, and that the mist eliminator unit is mounted inside the inner wall.
