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,.

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 few hours.

A common form is a ,spray tower,, in which the ,gas, flows upward ,through, a bank or successive banks of ,spray, nozzles. Similar arrangements are sometimes used in ,spray, chambers with horizontal ,gas, flow. Such devices have very low ,gas, pressure drops, and all but a small part of the contacting power is derived from the liquid stream.

through a trombone cooler and then conducted to the ammonia distillation tower, and the phenol recovery column. Ammonia from the distillation tower and coke oven gas which still contains small amount of ammonia are both passed through sulphuric acid saturators. The ammonia reacts almost quantitatively with the acid to form ammonium sulphate, the

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.

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

A shifted product gas 28 is drawn from the top of the reaction vessel 18. Some ammonia gas leaves the reactor 10 in the product gas 28 so that makeup catalyst solution must be added to the reactor continuously or periodically. The product gas 28 can be passed through another quench tower if recovery of the entrained ammonia is desired.

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.
