Abstract

Given that power blackouts occur very infrequently, a TRANSportable GENset emissions reduction system (XGEN) that fixes a larger and more significant problem of reducing emissions from routine periodic testing of gensets, whereas the system may be scheduled to be shared by a multitude of gensets, thereby reducing costs through efficient use of capital expenditures while also increasing the quality of emissions reductions as compared to applying individual exhaust treatments each genset.

Claims (40)

1. A road-transportable genset emissions reduction system comprising:

a connector configured to temporarily couple to an exhaust pipe of a genset producing exhaust gas;

a road-transportable exhaust treatment container for purifying said exhaust gas from said genset, said exhaust treatment container having length, width and height dimensions conforming to a universal standard for a shipping container;

an exhaust treatment system contained within said exhaust treatment container and configured to purify said exhaust gas from said genset;

said exhaust treatment container comprising an inlet and an outlet, the inlet connected to an input of the exhaust treatment system, the outlet connected to an output of the exhaust treatment system;

a public-road-transportable chassis configured to mount said exhaust treatment container for transportation on public roads in a transport mode;

wherein the chassis and said exhaust treatment container as mounted together have an overall height which meets maximum height limits to be moved over public roads without special permitting;

said exhaust treatment container mounted on said chassis;

an inlet duct configured to convey said exhaust gas from said connector to said inlet of said exhaust treatment container;

a crane configured to support said connector and said inlet duct, the crane configured to position the connector in relation to said exhaust pipe of said genset, the crane configured for transport over standard roads;

the exhaust treatment system configured to treat said exhaust gas in an operating mode to reduce selected pollutants from said exhaust gas.

2. The road-transportable genset emissions reduction system of claim 1 , wherein said crane is selected from the group consisting of a driving crane, a mobile articulating crane, a combination of articulating and telescopic mobile crane, and a converted mobile concrete pumping crane.

3. The road-transportable genset emissions reduction system of claim 1 , whereas said transportable genset emissions reduction system is configured to be sequentially shared with a plurality of backup gensets.

4. The road-transportable genset emissions reduction system of claim 1 , whereas exhaust treatment provided by the exhaust treatment system reduces the mass flow rate of particulate matter from said genset.

5. The road-transportable genset emissions reduction system of claim 4 , whereas the reduction of particulate matter utilizes a diesel particulate filter that is configured to be regenerated and the regeneration of said diesel particulate filter is selected from the group consisting of passive regeneration, passive regeneration using nitrogen dioxide, active regeneration, active regeneration using an electrical current through metal media, and active regeneration with electric heat.

6. The road-transportable genset emissions reduction system of claim 5 , whereas said diesel particulate filter is selected from the group consisting of ceramic honeycomb, catalyst-embedded ceramic filters, thermal oxidizers, ceramic filter elements, high temperature composite ceramic filter, filter elements comprising ceramic fibers, electrostatic precipitators, woven metal or ceramic media, ceramic foams, metal sintered filters, metallic foams, fiber wound filters, fiber knit filters, fiber woven filters, bound ceramic fibers, filter paper, filter felts, filter fleece, carbon filters, HEPA filters, vacuum filters, wall-flow filters and/or partial-flow filters.

7. The road-transportable transportable genset emissions reduction system of claim 1 , whereas exhaust treatment provided by the exhaust treatment system is configured to reduce the mass flow rate of oxides of nitrogen from said genset.

8. The road-transportable transportable genset emissions reduction system of claim 7 , further comprising a reagent and a catalyst, said reagent is selected from the group consisting of urea and anhydrous ammonia, and said catalyst is selected from the group consisting of Vanadium-Titanium, Titania, Vanadium, Zeolite, Copper-Zeolite-based, Iron-Zeolite-based, and Titania-supported Vanadia.

9. The road-transportable genset emissions reduction system of claim 1 , whereas said exhaust treatment provided by the exhaust treatment system reduces the mass flow rate of oxides of sulfur from said genset.

10. The road-transportable genset emissions reduction system of claim 1 , whereas exhaust treatment provided by the exhaust treatment system is configured to reduce the mass flow rate of volatile organic compounds from said genset.

11. The road-transportable genset emissions reduction system of claim 1 , whereas said exhaust treatment system is configured to reduce the mass flow rate of reactive organic gases from said genset.

12. The road-transportable genset emissions reduction system of claim 1 , whereas said exhaust treatment system is configured to reduce the mass flow rate of carbon dioxide from said genset.

13. The road-transportable genset emissions reduction system of claim 12 , whereas said exhaust treatment system is configured to separate said carbon dioxide as a gas product, liquid product, or a solid product.

14. The road-transportable genset emissions reduction system of claim 1 , whereas said exhaust treatment system comprises a fan or blower.

15. The road-transportable genset emissions reduction system of claim 1 , whereas said transportable genset emissions reduction system reduces noise from said genset.

16. The road-transportable genset emissions reduction system of claim 1 , whereas said exhaust treatment container is less than 53 feet long, 10 feet wide, and 9.5 feet tall.

17. A method for reducing emissions from a plurality of gensets using the road-transportable genset emissions reduction system of claim 1 , the method comprising:

(i) coupling the connector to an exhaust pipe of a first of the plurality of gensets to capture an exhaust gas using the crane;

(ii) drawing said exhaust gas through the inlet duct to an exhaust treatment container;

(iii) purifying said exhaust gas with the exhaust treatment system to reduce selected pollutants;

(iv) transporting the connector, the inlet duct and the exhaust treatment container with the exhaust treatment system over public or private roads to another of the plurality of gensets;

(v) repeating steps (i) through (iv) to sequentially conduct emission treatment operation on other gensets of the plurality of gensets.

18. The road-transportable genset emissions reduction system of claim 1 , wherein said system is configured to process emissions from land-based gensets.

19. The road-transportable genset emissions reduction system of claim 1 , the container has a height no larger than that of a standard single-height container.

20. A method for reducing emissions from a plurality of land-based gensets, the method comprising:

(i) coupling a connector to an exhaust pipe of a first of the plurality of gensets to capture an exhaust gas using a crane;

(ii) drawing said exhaust gas through a duct to at least one exhaust treatment container;

(iii) purifying said exhaust gas with an exhaust treatment system housed within the at least one container to reduce selected pollutants;
