Lecture 6 – Natural Gas Natural Gas: Composition C x H (2x+2) Natural Gas: Characteristics Consist mainly of methane (CH 4 ), some heavier hydrocarbons (ethane, propane and butane), and N 2 and CO 2 . CO 2 content as high as 70% by volume Desirable fuel because: o Easy to combust as a gas o Easily mixes with air o Furnace size is less than those for coal and oil o Combusted gas is used to directly drive the turbine o Produce 1/2 the amount of CO 2 per unit heating value as does coal and 3/4 as much as oil Methane is an important green-house gas: o CH 4 is a stronger absorber of infrared radiation than CO 2 per molecule o Concentration are low – 1.7 ppmv o Assuming continued growth of CH 4 and CO 2 in the atmosphere, by 2100 o CH 4 may contribute as much as 15% to global warming Natural Gas: Production and Consumption Trillion cubic feet World Natural Gas Consumption by Region at 2000 (Highest to Lowest) o North America o Russia/Soviet Union o Europe
