Gas scrubbing systems remove particulates and gaseous contaminants, including hydrogen chloride, hydrogen sulphide, ammonia and sulphur dioxide, from industrial flue gases. Read More
With wet scrubbers the flue gases are brought into contact with liquid scrubbing solutions that remove the contaminants. Various systems are available.
In packed tower scrubbers the gas travels up through a packed structure, meeting the scrubber liquid on its way down. Loose fill media provides a large surface area for the gas and liquid to make contact.
Moving bed scrubbers operate in a similar manner, except that the fill consists of hollow plastic spheres that move in a turbulent manner. The constant motion means that there are no routes through the scrubber that can become plugged.
With venturi scrubbers the waste gases are accelerated through a venturi throat. A scrubbing liquid is injected into this fast-moving stream and is immediately atomised, resulting in the pollutants being captured by the droplets.
With dry scrubbing systems a dry sorbent is added to the gas stream, which reacts with specific compounds. Coal ash and lime are used, for example, to remove SO2 from flue gases.
