Dry Injection Scrubbing Systems

Amerair offers a wide variety of dry injection scrubbing systems which provide very economical control solutions where hydrogen chloride, hydrogen fluoride, sulfur dioxide, bromides, mercury, furans and dioxins are present in the outlet emissions. Depending upon the effluent and its concentration in the gas stream, removal efficiencies can vary widely from fifty to the high ninety percent range. Amerair has good experience with several reagents in absorbing the desired effluent including :

• Sodium Bicarbonate
• Sodium Sequicarbonate
• Calcium Hydroxide
• Dry powder activated carbon

Amerair’s experience with hot gas processes where these effluents are present allows accurate assessment of the dry injection system’s performance to include:

• Stoichiometric ratio of reagent to effluent for desired removal efficiency
• Reagent utilization factor
• Proper handing of reagent in system
• Proper introduction of reagent to achieve best removal efficiency
• Proper design of baghouse collection to insure good distribution and reagent effectiveness
