HCl Abatement (Hydrochloric Acid)

In cement kiln operations, brick and structural clay manufacture, energy-from-waste plants and municipal and medical waste incinerators, chlorides present in the fuel source will be converted to HCl during combustion. As most coal contains some amount of chlorine compounds, any coal-fired process will also generate HCl. HCl, corrosive to human tissue, contributes to acid rain and the formation of smog.

The SOLVAir Approach

When used as a dry sorbent injected into a baghouse or exhaust duct, SOLVAir Select 200 trona readily reacts with acid gases.

It removes SO₂, SO₃, Hg, and HCl at higher rates than lime.

SOLVAir Select 300 sodium bicarbonate is a safe, non-corrosive approach for Dry Sorbent Injection (DSI) applications. Sodium bicarbonate reacts very rapidly with acid gases and can achieve very high levels of acid gas removal when used properly in a DSI system.

Select 200 was tested in two separate municipal solid waste facilities for HCl removal. Select 300 indicates equal or better results in other testing and field experience.
