Pollutants emitted from combustion are associated with human health and environmental risks. Acid deposition, or acid rain as it is commonly known, occurs when SOx and NOx react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds that later fall to earth in the form of precipitation or dry deposition of acidic particles. They contribute to the damage of trees at high elevations and in some regions lakes and streams may become so acidic that they cannot support aquatic life. In addition, acid deposition accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our collective cultural heritage.  We all will benefit from reduced air emissions with an improved ecosystem and human health.

Dry Desulfurization removes 99.9% of all sulfur oxides from flue gas. Dry injection of sodium bicarbonate powder into flue gas and the resulting sodium sulfate powder byproduct are both non-hazardous, food safe, pH neutral, non-pollutants. Dry Desulfurization systems are carbon neutral with lower total carbon emissions than sea water exhaust gas cleaning systems and low sulfur distillate fuels. Dry Injection Desulfurization (DID) provides a viable, sustainable and environmental solution to reduce harmful emissions.
