  • Patent number: 7803219
    Abstract: A method for treating waste gas containing inorganic acid is disclosed. The method includes the following steps: (a) forming a mixture of inorganic acidic gas and a nebulized alkaline solution wherein the nebulized alkaline solution can be produced continuously or periodically; (b) forcing the mixture to pass through an adsorbent bed; and (c) releasing the treated gas. An apparatus for treating the inorganic acid gas with the method illustrated above is also disclosed here. The method can regenerate poisoned adsorbents online, and save time, space and cost simultaneously.

  • Publication number: 20030027325
    Abstract: The invention discloses a method for processing alkene-containing exhaust gas. It is a combination of ozonic and biological processes which mainly deal with exhaust gas mixtures having alkene-containing (C—C double bond) organic exhaust gas (such as alkene, acrylic acid) and other volatile organic compounds (such as ketone, alcohol, BTEX, and others). Since exhaust gas containing C—C double bond is difficult to dispose of, the method for processing exhaust gas presented in the invention utilizes ozone to completely decompose or transform the organic contaminants with C—C double bonds into intermediate products. The organic contaminant can then be treated in the biological process and converted into non-toxic substances. This method does not require large-sized biological process equipment, and the residual ozone is oxidized and degraded in the bio-filter.
