Abstract

An apparatus for removing unwanted contaminates from gases, wherein the apparatus can include a housing that has at least one removable portion. The apparatus can also include a reaction chamber formed within the housing. A cartridge can be disposed in the reaction chamber. The cartridge can be connected to the removable portion of the housing.

Claims

1. An apparatus for removing unwanted contaminates from gases, wherein the apparatus comprises:

a. a housing comprising at least one removable portion;

b. a reaction chamber formed within the housing;

c. a cartridge disposed in the reaction chamber, wherein the cartridge is connected to the removable portion of the housing, wherein the cartridge comprises;

(i) a gas transmitting floor comprising a sintered permeable membrane, wherein the sintered permeable membrane has a first side and a second side, and wherein the sintered permeable membrane is disposed across the reaction chamber; and

(ii) a non-gas transmitting portion connected with the gas transmitting floor, wherein a space is formed between a first portion of the housing, wherein at least a portion of the reaction chamber, the cartridge, and the space contains a lean liquid, and wherein at least a portion of the lean liquid in the reaction chamber, the first cartridge portion, and the space form a reaction zone, and wherein the lean liquid is adjacent to or covers the first side and the second side of the sintered permeable membrane;

d. an inlet in fluid communication with the space, wherein the inlet is configured to provide pressurized contaminated gas to the space;

e. a gas exit port in fluid communication with a second cartridge portion and the reaction chamber; and

f. a demister pad connected with the gas exit port.

2. The apparatus of claim 1, wherein the sintered permeable membrane comprises pores with different pore sizes.

3. The apparatus of claim 1, further comprising a pressure relief valve operatively disposed on the housing.

4. The apparatus of claim 1, wherein the sintered permeable membrane comprises a plurality of pores, wherein the plurality of pores have varying pore sizes.

5. The apparatus of claim 1, wherein the sintered permeable membrane has a pore size from 10 microns to 10,000 microns.

6. The apparatus of claim 1, wherein the sintered permeable membrane is from 1/32 of an inch thick to 24 inches thick.

7. The apparatus of claim 1, wherein the sintered permeable membrane 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 thereof.

8. The apparatus of claim 1, wherein the housing further comprises a drain port in fluid communication with the reaction zone.

9. The apparatus of claim 8, further comprising a drain valve connected with the drain port, and wherein the drain valve is configured to control a flow rate through the drain port.

10. The apparatus of claim 1, wherein the lean liquid comprises a liquid adsorbent, a liquid solubilizer, a liquid absorbent, a liquid reacting agent, water, surfactants, a biomass, biodiesel, or combinations thereof.

11. The apparatus of claim 1, wherein the contaminates comprise volatile organic compounds, hazardous air pollutants, hydrogen sulfides, ammonia, sulfur dioxide and combinations thereof.

12. The apparatus of claim 1, further comprising a liner disposed on at least a portion of an inner surface of the cartridge.

13. The apparatus of claim 1, further comprising a housing liner disposed on at least a portion of an inner portion of the housing.

14. The apparatus of claim 1, further comprising a base operatively connected with the housing.

15. The apparatus of claim 14, wherein the base comprises a plurality of support members connected with the housing.

16. The apparatus of claim 1, further comprising an inlet check valve connected with the inlet, wherein the inlet check valve is configured to prevent back flow from the reaction chamber.

17. A system for removing unwanted contaminates from gases comprising a plurality of apparatuses for removing unwanted contaminates from gases, wherein the apparatuses are connected in series, in parallel, or combinations thereof with a contaminated gas source, and wherein each apparatus of the plurality of apparatuses comprises:

a. a housing comprising at least one removable portion;

b. a reaction chamber formed within the housing;

c. a cartridge disposed in the reaction chamber, wherein the cartridge is connected to the removable portion of the housing, wherein the cartridge comprises;

(i) a gas transmitting floor comprising a sintered permeable membrane; and

(ii) a non-gas transmitting portion connected with the gas transmitting floor, wherein a space is formed between a first portion of the housing, wherein at least a portion of the reaction chamber, the cartridge, and the space contains a lean liquid, and wherein at least a portion of the lean liquid in the reaction chamber, the first cartridge portion, and the space form a reaction zone;

d. an inlet in fluid communication with the space formed between the gas transmitting floor and the first portion of the housing, wherein the inlet is configured to provide pressurized contaminated gas to the space;

e. a gas exit port in fluid communication with a second cartridge portion and an the reaction chamber; and

f. a demister pad connected with the gas exit port.

18. An apparatus for removing unwanted contaminates from gases, wherein the apparatus comprises:

a housing, wherein the housing is configured to exhaust scrubbed gases and receive contaminated gases, wherein the housing comprises a removable portion, wherein the removable portion is connected with a sintered permeable membrane;

wherein a lean liquid is adjacent to or covers a first side and a second side of the sintered permeable membrane.
