Definitions
- TITLE Waste gas filtering absorbing carbon dioxide
- the invention concerns waste gas filtering with water glass and products made of the filter materials in continuation of or in immediate connection with the filtering process.
- Fig. 1 In Fig. 1 is seen that waste gas from chimney extraction is cooled followed by compression.
- the (porous) dilter material is impregnated / saturated with carbon dioxide. This may be done with or without vacuum.
- the filter material is impregnated with water glass (Na2SiO3, nH2O) in some state or other.
- water glass Na2SiO3, nH2O
- Waste gas contains fly ash, among other things, and carbon from PNC recycling contains lead oxides which together with the carbon dioxide emission are undesirable. According to the invention all these substances are bound in the filter material.
- the products derived from this process are noninflammable - also when cellulose is used as filter maerial - as they are saturated with both carbon dioxide and water glass ( ⁇ a2SiO3, nH2O) and thus are fully hardened. A great variation in porosity can also be achiebed through this process until cappillary breaking as well as low bulk density ( ⁇ 1.0).
