Absorbers will account for 45 percent of scrubber sales in 2014. The total market for scrubbers, including absorbers, biofilters, and adsorbers, will exceed $6.8 billion next year. This is the latest prediction in the McIlvaine Co. report Scrubber/Adsorber/Biofilter World Markets.
Absorbers will lead the way with revenues of $3.1 billion. These devices are used for acid gas capture. Sulfur dioxide (SO2), hydrogen chloride (HCl), and other acid gases are generated when ores with sulfides are processed. They are also a result of a number of chemical processes. Municipal waste-to-energy power plants use either absorbers or dry scrubbers to capture the hydrogen chloride created in the combustion of the plastics.
The cement industry is starting to purchase scrubbers to capture both HCl and SO2. New regulations in the U.S. are creating a significant market. However, other countries are also requiring cement plants to meet acid gas emission limits.
Adsorbers and biofilters are used for odor control and where the contaminant loadings are relatively low. Particulate scrubbers sales are strong in the developing countries, where they are a low-cost alternative to either fabric filters or electrostatic precipitators.
The market is growing fastest in Asia due to the expansion of industrial activity but also to the retrofitting of existing power plants to meet recently enacted standards.
