Scrubber Market Veering From Hardware to Consumables

Dry scrubber capital investment will be just under $600 million in 2015. This is less than 10 percent of the total scrubber capital investment. But behind these numbers is a new path for the industry. Dry scrubbing is a way to capture acid gases at lower capital cost than with absorbers. However, purchasers face much higher reagent costs. Limestone used in wet systems is a fraction of the $200/ton price of lime used in dry scrubbers. These developments are tracked in the McIlvaine publication Scrubber/Adsorber/Biofilter World Markets.

Power Plants Will Spend $400 Million for Dry Scrubber Systems This Year

Power plants still prefer wet limestone scrubber systems as a way to capture the SO2 emissions. However, more than 10 percent of the purchases will be for dry systems this year. This is the conclusion reached by the McIlvaine Company in FGD Market and Strategies

More Dry scrubber analysis from Kiewit

See previous articlesfor details but here is more: For the CFBs, a typical approach temperature is 30°F to 40°F, while for the NID a tighter approach of 25°F to 30°F is more common. Because the temperature is still maintained above saturation, reactor materials of construction are typically carbon steel. Type 316 L stainless steel is often used for specialty components such as water injection nozzles and some lime hydrator parts.

Dry scrubber options as listed by Kiewit

In addition to Graff-Wulff, Babcock Turbosorp, and Allied/Lurgi design provide the CFB options. SDA is more widely used but concern about atomizer O &M costs as well as distributing the slurry in droplets which will dry prior to reaching the particulate collector.
