The EPA recently issued its ICI Boiler MACT and MATS regulations, intended for emissions control of HAPs from industrial, commercial, institutional and utility boilers.
While these may be subject to change, compliance can be easy to attain, and that’s a good thing! SOLVAir Solutions offers real world applications where SOLVAir Select products sodium bicarbonate and trona are used to mitigate HCl, HF and other air pollutants.
SOLVAir Select Sodium Bicarbonate
For example, a low capital cost Dry Sorbent Injection (DSI) system which utilizes Select 300 sodium bicarbonate might be exactly what your plant needs. Considered BACT in the EU for treating HAPs, sodium bicarbonate works here too!
Select 300 sodium bicarbonate neutralizes acid gases very rapidly, especially SO2, and is able to achieve very high pollutant removal rates when used in a properly designed DSI system.
As the sodium bicarbonate enters the hot flue gas stream, it is rapidly converted to sodium carbonate particles with greatly increased surface area and porosity. Select 300 is particularly versatile because it is effective over a wide range of operating temperatures.
SOLVAir Select Trona
Used as a dry sorbent injected into DSI systems, Select 200 trona forms a safe, non-corrosive waste product that will not damage equipment.
Utilizing simple chemistry, trona effectively removes a variety of acid gases. In temperatures above 275°F, it is readily transformed into soda ash (sodium carbonate). Soda ash then reacts with the acids to form neutral sodium salts.
Both Select 200 trona and Select 300 sodium bicarbonate remove SO2, SO3, and HCl at higher rates than lime. Field testing shows removal rates of SO2 over 90%. Trona or sodium bicarbonate routinely achieve HCl removal of 95-99%. In addition, either of these products can help remove 20-70% Hg when used alone in high sulfur environments, and over 90% when used in combination with activated carbon.
Making decisions about air pollution control options is difficult. At SOLVAir Solutions, we have been working with the pulp and paper industry for years and understand the advantages of a DSI system.
