  • Patent number: 8801843
    Abstract: A system for removing unwanted contaminates from gases using a scrubber, which comprises a housing, a reaction chamber having a liquid level, an inlet connected to a source containing gases to be scrubbed with a contamination concentration greater than zero ppb to saturation. A gas exit port connected to the housing is used for evacuating scrubbed gas and a sintered permeable membrane is disposed across the reaction chamber, which provides a reaction zone in the plurality of pores when gases to be scrubbed are introduced to the membrane on a first side while the membrane is immersed in the lean liquid; and a cleaned gas on a second side wherein the clean gas initially has a drop in contamination concentration of at least 99 percent and gradually decreasing to 70 percent as additional gases to be scrubbed are introduced to the plurality of pores without replacing the lean liquid.

  • Patent number: 8337763
    Abstract: A system for removing unwanted contaminates from fluid using a scrubber, which comprises a housing, a reaction chamber having a liquid level, and an inlet connected to a source containing fluid to be scrubbed with a contamination concentration greater than zero ppb to saturation. An exit port connected to the housing used for evacuating scrubbed fluid and a sintered permeable membrane disposed across the reaction chamber, which provides a reaction zone in the plurality of pores when fluid to be scrubbed is introduced to the membrane on a first side while the membrane is immersed in the biodiesel or biomass and a cleaned fluid on a second side wherein the clean fluid initially has a drop in contamination concentration of at least 99 percent and gradually decreasing to 70 percent as additional fluid to be scrubbed is introduced to the plurality of pores without replacing the biodiesel or biomass.
