Dry Scrubber Design-Construct-Guide-Maintain Market to reach $9.6 billion in 2020

Traditionally wet scrubbers have been used for removing SO2, HCl and other acid gases. But recently owners have favored the newer dry scrubbing technologies. The capital cost is much lower and there is no wastewater disposal problem. The disadvantage is the higher use of reagents. However with new monitoring and data analytics tools the reagent use can be optimized and the total cost of acid gas capture reduced.

The big beneficiaries are the lime and other reagent suppliers. Their revenues will reach $6.4 billion in 2010.

The total design-construct-guide-maintain market will exceed $9 billion in 2020. The largest purchase will be the reagent. Increasingly process management software, wireless transmitters and data analytic will be utilized to most efficiently operate these systems. Some combination of SO2, HCl, SO3 and mercury often needs to be reduced. Multiple reagents e.g. lime and activated carbon may be needed.

There are a range of dry scrubbing technologies being utilized. Dry sorbent injection is the least capital intensive. Other technologies utilize vessels. One vessel type is the spray drier, another is a fluidized bed. A third design utilizes concurrent flow and recirculation of a portion of the reagent.

Fabric filters are typically used to capture the reacted product as well as the particulate.

Electrostatic precipitators are less frequently used due to their lower absorption efficiency.  

Applications include coal fired boiler, cement, glass, biomass, steel and waste to energy plants.
