Wet Scrubbers: A Key Tool Against Air Pollution Caused by Wood-Burning Household Stoves
Wood stoves are a major source of air pollution in both Chile’s capital Santiago and some cities in the country’s south. A wood stove can emit up to PM 10 μg/m3 (equivalent to the air pollution caused by 1,500 new cars). This problem is often compounded by the widespread use of highly-polluting wet wood.
The role played by water in reducing atmospheric CO2 is well known. Rain, for example, dissolves CO2 into bicarbonate, an ion which in lakes and rivers binds with certain anions to form carbonates.
We designed a system capable of reducing carbon dioxide emissions based on water recirculation. This process dissolves unwanted gases and converts them into carbonic acid, an easily-handled, weak, and environmentally-safe aqueous solution.
