Emergency Scrubbers (Absorbers) Emergency relief effluent streams are often sent to scrubbers (also called absorbers, columns, or towers) for final disposal by absorption of the gas into a solvent. Some gases or vapors can be removed by physical absorption. Other gases or vapors can be removed by chemical absorption (reaction of the vent gas/vapor into a liquid that reacts with it). 

Emergency Scrubbers (Absorbers) Emergency relief discharges are often passed through scrubbers (also called absorbers, or absorption columns or towers) for removal of flammable, corrosive, or toxic chemicals. The removal mechanism in some scrubbers involves physical absorption in a solvent, whereas in others chemical absorption (reactive scrubbing) is required. 

Gas scrubbers absorb contaminants from the gas that is fed through them. Liquid gas scrubbers as we describe here, provide a safety feature also, in that they act as flashback arrestors as well.

DISPOSAL AND STORAGE METHODS add contaminated amine to layer of sodium bisulfate, spray with water, neutralize, and route to sewage plant dissolve in flammable solvent and bum in incinerator equipped with afterburner and scrubber absorb in dry earth, sand or vermiculite and place in a secured sanitary landfill store in a cool, dry location with adequate ventilation separate from oxidizing materials, acids, noncombustibles, and sources of halogens. 

Spray scrubbers, absorbers and reactors have been discussed elsewhere. Here the focus is on the actual generation of the spray. 

In spray scrubbers absorbent is sprayed (dispersed) into the gas phase. Dispersion equipment are usually nozzles mounted vertically on top of each other or horizontally in a row. Liquid and gas phases are in cocurrent or countercurrent flow (Fig. 3-20). Spray scrubber examples are annular gap scrubbers and radial-flow scrubber. 

Countercurrently operated packed scrubbers are one method for controlling malodorous emissions. A wet scrubber absorbs the malodorous material into the liquid phase however, many of these substances have limited solubility in water. If the scrubber operates with a once-through water flow, the effluent liquid may be a source of water pollu-...
