Types of pollutant sampling and measurement

Effluent gases are passed ,through, absorber (scrubbers) which contain liquid absorbents that remove one or more of the ,pollutants, in the ,gas, stream. The efficiency of this process depends on 1. Amount of surface contact between ,gas, and liquid 2. Contact time 3. Concentration of absorbing medium 4. Speed of reaction between the absorbent and ,gas

In this process stage partial cleaning is carried out to remove odours, ,ammonia, and above all dusts. ,After, this the pre-cleaned air flows ,through, washing wall 2, which is permanently sprinkled with an ,acid, washing solution and is also approx. 0.15 m thick. The pH value in this washing stage is generally kept at pH 5 by adding a dose of ,acid,.

In wet scrubbing systems, the flue ,gas, normally ,passes, first ,through, a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO2-absorber. However, in dry injection or ,spray, drying operations, the SO2 is first reacted with the sorbent, and then the flue ,gas passes through, a particulate control device.

Orifice Scrubbers • The ,gas, is impacted onto a layer of the scrubbing liquid. • The ,gas passes through, the liquid, thus removing almost all the particulate matter, and a large portion of the probable gases. • ,After, coming out of the liquid, the ,gas, is passed ,through, baffles to remove the liquid droplets. 73.

Orifice scrubbers are a group of ,gas,-atomised ,spray, scrubbers where a tube or a duct forms the ,gas,-liquid contacting zone. The particle-laden ,gas, is passed over the surface of a scrubbing liquid at high velocity. The ,gas, stream flowing ,through, the orifice atomises the entrained liquid droplets in the same way as a venturi scrubber.

A ,spray tower, is the simplest type of scrubber. It consists of a ,tower, with ,spray, nozzles, which generate the droplets for surface contact. ,Spray, towers are typically used when circulating a slurry (see below). The high speed of a venturi would cause erosion problems, while a packed ,tower, would plug up if it tried to circulate a slurry.

Hydrogen sulfide ,gas, turns into hydrosulfuric ,acid, when it dissolves in water. The ,acid, is weak but highly corrosive, eating up electrical contacts, causing a slight odor, and resulting in black water complaints. Water containing hydosulfuric ,acid, will become very dark ,after, remaining in the water lines for a …
