Synthesis gas consists of a nonhydrocarbon mixture (H2‚CO) obtain- able from more than one source. It is included in this chapter and is fur- ther noted in Chapter 5 in relation to methane as a major feedstock for this mixture. This chapter discusses the use of synthesis gas obtained from coal gasification and

India’s net2 imports of energy (petroleum‚ coal and gas) increased from 129 mtoe (million tons oil equivalent) in 2006 to 191 mtoe in 2010 representing a growth of 10% p.a. This is likely to increase to about 227 mtoe in 2011-12. Supply and demand projections for the 12th five year plan indicate

Built in 1923 as a coal-powered operation‚ the High Bridge plant‚ along with Riverside in Minneapolis‚ once formed the hub of Northern States Power Company‚ a predecessor to Xcel Energy. The original plant was replaced with a new natural gas fired generating facility starting in 2005 as part of Xcel Energy’s Metro Emission Reduction Project. The coal-fired plant was retired in 2007 and the new facility came on line in May 2008. (High Bridge Generating Station) One interesting feature about the

Answer: The management of OMPIC wants to determine the mix of coals that will maximize the amount of power produced per hour. The decision variables are how many tons of Hard Coal and Soft Coal should be used to maximize the amount of power in BTU per hour while complying the with the emission standards. H= tons of Hard Coal should be used per hour. S= tons of Soft Coal should be used per hour. The objective function: maximize

rock layers to intersect the coal seem that contains coal bed methane‚ CBM. Next‚ fractures are created or existing fractures are enlarged in the coal seem so that the CBM can be drawn from the well and pumped to the surface. These fractures are created or enlarged by using a thick water-based fluid which is gradually increased by rate and pressure. Then‚ over time the coal seam is unable to keep up with the fracturing fluid which results in high pressure causing the coal to fracture along the weaknesses
