Stranded natural gas, when contaminated by difficult to remove constituents such as Nitrogen and Oxygen, has long been considered uneconomical to process into pipeline quality gas and is abandoned or utilized in other energy applications where economically viable. Landfill Gas (LFG) is often considered a stranded gas although in many instances it is available at reasonable distances to natural gas pipelines, and has only rarely been processed for injection into natural gas pipelines. Other stranded contaminated gases, such as gases vented from remote oil wells or coal beds where access to transportation pipelines is not feasible are also candidates for collection. In many instances, billions of cubic feet of methane rich LFG has been vented or flared into the atmosphere. The present invention utilizes a variety of components and provides a product gas that will meet all known pipeline requirements and / or vehicle fuel specifications without the need for blending with pipeline gas and without using cryogenic separation techniques or partial cryogenic processes. The invention also provides a product gas suitable for further processing into Liquefied Natural Gas.

A method of reducing a modified Wobbe index of a fuel stream fed to diffusion combustors of a gas turbine that is used in connection with an IGCC installation in which a nitrogen stream is fed into the head ends of the combustor of NOx control and the modified Wobbe index of the fuel stream has been increased in an amount that is greater than at least about 10 percent of a design Wobbe index for the fuel to be fed to the gas turbine. The reason for the increase is the conversion of the carbon monoxide within the fuel stream to hydrogen and carbon dioxide by a water gas shift reaction and subsequent removal of the carbon dioxide. The nitrogen stream is maintained at the same level both with and without conversion and subsequent removal of carbon atoms. The nitrogen stream is divided to subsidiary streams that are respectively fed into the head end of the combustors and that are mixed with a fuel to lower the modified Wobbe index to acceptable levels for the gas turbine.

This invention relates to a forest, terrain and urban fire fighting device and method, and more particularly, to a fire extinguishing system and method offering reduced risk of fire spread and safety of firemen. This extinguishing device consists of an encapsulated cryogenic projectile with a payload of solidified and frozen mixture of carbon dioxide, nitrogen, combination of gases and compacted solid extinguishing agents. These strategically located and cryogenically stored devices are launched at the outbreak of fire, aerially or terrestrially over a blaze. An embedded explosive charge is detonated at a predetermined and optimum height causing the solidified gases / compacted solid extinguishing agents to be dispersed instantaneously and forcefully over targeted and specified areas. The release of high pressure, low temperature oxygen exclusion gases penetrate the fire from above, chills the substrate and extinguishes the fire. As carbon dioxide is heavier than air it hangs as a cloud over the extinguished substratum effectively preventing reignition. Fly ash, fine quarry dust or any solid or semisolid extinguishing agent can also be made to disperse under force over the fires in the same mode which cuts off the oxygen supply to the burning substrates. By effectively checking and cooling the fuel complex substrate by successive pulverizations as needed this invention enables a low cost, scalable, and effective urban, terrain and forest fire intervention / extinguishing process.
