System for removing unwanted contaminates from fluids
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.
1. A system for removing unwanted contaminates from fluid, wherein the system comprises:
a. a source containing fluid to be scrubbed, wherein the fluid to be scrubbed has a contamination concentration greater than zero ppb to contamination saturation; and
b. a scrubber comprising:
(i) a housing with a reaction chamber, wherein a portion of the reaction chamber contains a biodiesel or biomass, and wherein a reaction zone is formed below a liquid level of the biodiesel or biomass;
(ii) an inlet in the housing connected to the source, and wherein the inlet is disposed below the liquid level of the biodiesel or biomass; and
(iii) an exit port connected to the housing adapted for evacuating scrubbed fluid; a sintered permeable membrane disposed in the reaction zone, wherein the sintered permeable membrane is configured to contact the fluid to be scrubbed that have been in prior contact with the biodiesel or biomass in a portion of the reaction chamber, and wherein the sintered permeable membrane provides an interface for enhanced contact of the fluid to be scrubbed and the biodiesel or biomass, and wherein the sintered permeable membrane is sandwiched between two pad grids, wherein the two pad grids secure the sintered permeable membrane in the housing, and wherein the sintered permeable membrane comprises open spaces that are from 40 percent to 50 percent, and wherein the sintered permeable comprises a member of the group consisting of: ceramic, carbon steel, other steel alloys, copper, copper alloys, carbide gel, other carbide materials, carbide films, polyamides, tungsten, polypropylene, carbon aerogels, ferrite magnets, silicon, polyethylene, polybutylene, homopolymers and copolymers thereof, acetates, glass, silica, and combinations of these materials.
2. The system of claim 1 , wherein the sintered permeable membrane comprises pores with different pore sizes.
3. The system of claim 1 , wherein the housing further comprises a drain port disposed through the housing communicating with the reaction zone.
4. The system of claim 3 , further comprising a drain valve for controlling flow from the drain port disposed between the housing and a collection tank.
5. The system of claim 1 , wherein the contaminates comprise volatile organic compounds, hazardous air pollutants, hydrogen sulfides, ammonia, sulfur dioxide and combinations thereof.
6. The system of claim 1 , wherein the housing further comprises a liner within the housing surrounding the reaction zone.
7. The system of claim 1 , further comprising an exit conduit connected to the exit port.
8. The system of claim 7 , further comprising a knock out canister disposed between the exit conduit and a vent.
9. The system of claim 1 , further comprising a pedestal for supporting the scrubber, wherein the pedestal comprises a pedestal access port connecting to a drain port located on the housing.
10. The system of claim 1 , further comprising a manway disposed in the housing for providing access to the reaction chamber.
11. The system of claim 1 , further comprising an inlet check valve to control a flow of the fluid to be scrubbed through the inlet.
