These two methods are called wet scrubbing, and carbon polishing.

The suppressed combustion system off-gases are normally cleaned by wet scrubbing.

Pre-sweeping, wet scrubbing and dry vacuuming in one operation.

Perhaps the most widely used technology for the desulphurisation of flue gases is 'Wet Scrubbing'.

Approximately 79% of the units, representing about 199 gigawatts of capacity, were using lime or limestone wet scrubbing.

The particulates contained in the off-gas from the shaft furnace are collected by wet scrubbing and recycled in the process(10).

Emission control technology has been developed for charging and pushing emissions which utilize wet scrubbing, electrostatic precipitators and fabric filters.

Standard treatment procedures span from filtration to wet scrubbing (using liquid to remove gaseous contaminants), though the exact procedures depend on the gases being treated.

Off-gases from the TBRC are treated by wet scrubbing to remove dust and fume containing volatile metals and metal oxides.

Inco Copper Cliff Wet scrubbing of Fluid Bed Roaster off-gas Cost: $60 to 80 million Reduction:

Wet scrubbing is well established as an efficient and highly reliable method of flue gas desulphurisation with high sulphur coal and total installed capacity world-wide is over 75GWe.

A type of basic oxygen process furnace, in which oxygen supply to the furnace is limited to convert carbon to carbon monoxide. The suppressed combustion system off-gases are normally cleaned by wet scrubbing.

Nevertheless adsorption may have a use, albeit more limited, in that industry, namely as a final method of odour removal following exhaustive pretreatment of the odorous air by other methods such as wet scrubbing or oxidation.

The open combustion system off-gases are cleaned either by wet scrubbing (wet-open combustion) or by dry electrostatic precipitation (dry-open combustion). Particulates are any finely divided solid or liquid particles in the air or in an emission.

Absorption or wet scrubbing as it is often called has however the disadvantage of having to dispose of the liquid effluent obtained, which may itself require treatment before disposal, and has led to the comment that we may be merely replacing one effluent problem by another by using this method.
