The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.
For many years, sodium bicarbonate has been used to reduce acid gas stack emissions in industries including coal-fired power plants and waste incinerators. SOLVAir Select 300 sodium bicarbonate provides an alternative approach for dry sorbent injection applications. It reacts very rapidly with acid gases and is able to achieve very high levels of removal of these pollutants when used in a properly designed DSI system.
