  • System and method for removing a contaminant from a gas stream
    Patent number: 8652428
    Abstract: A system and method for removing contaminants from a gas stream is provided. The method can include the steps of reacting the gas stream with ozone to form solid contaminant particles and separating the solid contaminant particles from the gas stream. The solid contaminant particles can he separated from the gas stream using an adsorption material.
    Type: Grant

  • Method and device for hydrogen sulfide abatement and production of sulfuric acid
    Patent number: 6056934
    Abstract: A process is provided for removing hydrogen sulfide out of gas, such as gas separated from geothermal brine, by passing the hydrogen sulfide containing gas and oxygen containing gas through a bioreactor containing bacteria, such as Beggiatoa, Thiothrix and Thiobacilli, supported on a support so that the bacteria oxide the hydrogen sulfide into elemental sulfur, which is subsequently oxidized into sulfuric acid. The flow of the gases through the bioreactor is cyclically reserved about every 12 hours to about 5 days so as to provide a better sulfur distribution in the support, resulting in more efficient oxidation of the elemental sulfur into sulfuric acid. Hydrogen sulfide depleted gas and sulfuric acid are discharged from the bioreactor. A plurality of bioreactors may be used, connected in series or in parallel.
