CO2 removal is one of the key technological requirements in biogas purification. A technique using a gas–liquid mixing pump to capture CO2 and coproduce nano calcium carbonate was devised and tested in this work. The characteristic curves and CO2 absorption efficiency of the pump were investigated. The CO2 content of the end gas in all experiments was less than 2%, and the calcium carbonate ...

Calcium carbonate has the chemical formula CaCO3. In nature, marble, limestone and chalk contain calcium carbonate. By processing calcium carbonate from marble, one obtains precipitated calcium carbonate, which is ground into a powder called ground calcium carbonate. Ground calcium carbonate has many industrial, medicinal and pharmaceutical uses.

When carbon dioxide is lost from the biogas, a partial vacuum condition develops under the digester dome. This condition may cause the digester cover to collapse. Also, as the concentration of alkalinity increases in the anaerobic digester, the continued use of quick lime results in the precipitation of calcium carbonate (Equation ).
