Patent ID: 7803337

Claim:
A method for treating fluid to be scrubbed, comprising: a. filling a scrubber having a reaction chamber with biodiesel or biomass that covers a sintered permeable membrane disposed across in the reaction chamber and additionally fills the reaction chamber an additional 20 percent; b. introducing the fluid to be scrubbed from a source to the reaction chamber on a first side of the sintered permeable membrane(s); c. building up pressure in the reaction chamber forming a reaction zone in the sintered permeable membrane(s); d. intermingling the fluid to be scrubbed with biodiesel or biomass in the sintered permeable membrane(s); e. forming a reaction zone above the sintered permeable membrane(s); f. producing scrubbed fluid in the reaction zone; and g. passing the scrubbed fluid to an exit port at a rate equal to the rate which the fluid to be scrubbed is treated in the reaction zone while creating a pressure drop of at least 0.2 psi in the reaction chamber wherein the scrubbed fluid has an initial drop in contamination concentration of at least 99 percent gradually decreasing to 70 percent as additional fluid to be scrubbed is introduced to the sintered permeable membrane without replacing the biodiesel or biomass.
