possible to make coal a fuel source that is free of (or very low in) carbon dioxide emissions and other pollutant emissions. Some of the techniques that would be used to accomplish this include chemically washing minerals and impurities from the coal‚ gasification (see also IGCC)‚ treating the flue gases with steam to remove sulfur dioxide‚ carbon capture and storage technologies to capture the carbon dioxide from the flue gas and dewatering lower rank coals (brown coals) to improve the calorific value‚

At present‚ the people are facing severe loadshedding/blackout problems due to shortage of power supply. Industries are closing down. Millions of Man hours have been lost leading to an increase in poverty and economic loss of billions of rupees to the country. It is happening despite the facts that about 60% of Pakistan’s population has an access to electricity. And according to World Energy Statistics 2011‚ published by IEA‚ Pakistan’s per capita electricity consumption is one-sixth of the World

companies are looking to unconventional fuel resources. This means the fuel is extracted via another method then the conventional well strategy. These resources include fracturing of oil and gas source rocks‚ methane hydrates‚ tar sands and coal seam gasification. There are benefits such as energy security and economic growth associated with these resources. However‚ there are environmental disadvantages which may prove detrimental to sustainability and an uncertainty in the future of energy. Currently

Garrets Flash Pyrolysis Process: This low temperature Pyrolysis process has been developed by Garrett Research and Development Company. In a 4 tonnes per day pilot plant set up by the company at La Varne‚ California‚ the solid waste is initially coarse shredded to less than 50mm size‚ air classified to separate organics / inerts and dried through an air drier. The organic portion is then screened‚ passed through a hammer mill to reduce the particle size to less than 3mm and then Pyrolysed in a reactor

Fired Boiler World Market Characteristics and use of blast furnace gas (BFG) Iron and steel industry produce large amounts of combustible gas in the production process‚ blast furnace gas production in blast furnace coke after the change obtained by gasification. BFG fired boiler has been developed for a wider application in the world steel industry. This low calorific value blast furnace gas‚ if not utilized‚ will diffuse into the atmosphere caused by environmental pollution and waste of energy. BFG system

Overview(larson & toubro) The evolution of L&T into the country’s largest engineering and construction organization is among the most remarkable success stories in Indian industry. L&T was founded in Bombay (Mumbai) in 1938 by two Danish engineers‚ Henning Holck-Larsen and Soren Kristian Toubro. Both of them were strongly committed to developing India’s engineering capabilities to meet the demands of industry. Beginning with the import of machinery from Europe‚ L&T rapidly took on engineering and

Solid waste management Introduction to solid waste management Solid waste is the unwanted or useless solid materials generated from combined residential‚ industrial and commercial activities in a given area. It may be categorised according to its origin (domestic‚ industrial‚ commercial‚ construction or institutional); according to its contents (organic material‚ glass‚ metal‚ plastic paper etc); or according to hazard potential (toxic‚ non-toxin‚ flammable‚ radioactive‚ infectious etc).
