Coal gasification offers one of the most versatile and clean ways to convert coal into electricity.
Coal gasification offers one of the most versatile and clean ways to convert coal into electricity, hydrogen, and other valuable energy products. Coal gasification electric power plants are now operating commercially in the United States and in other nations, and many experts predict that coal gasification will be at the heart of future generations of clean coal technology plants. Rather than burning coal directly, gasification (a thermo-chemical process) breaks down coal - or virtually any carbon-based feedstock - into its basic chemical constituents. In a modern gasifier, coal is typically exposed to steam and carefully controlled amounts of air or oxygen under high temperatures and pressures. Under these conditions, molecules in coal break apart, initiating chemical reactions that typically produce a mixture of carbon monoxide, hydrogen and other gaseous compounds. Gasification, in fact, may be one of the most flexible technologies to produce clean-burning hydrogen for tomorrow's automobiles and power-generating fuel cells. Hydrogen and other coal gases can also be used to fuel power-generating turbines, or as the chemical "building blocks" for a wide range of commercial products. (Read more about hydrogen production)
In Enugu rich in coal deposits the coal can be used to power street lights and other power dependent sectors. while coal gas it's presently diesel is about 200 Naira a litre and an average 100kva consumes more than 30 litres a day. Calculating these figures for the number of Generators scattered around the city. Millions of Naira is spent of power generation. While same result will be archived from coal gas. The environmental benefits of gasification stem from the capability to achieve extremely low SOx, NOx and particulate emissions from burning coal-derived gases. Sulfur in coal, for example, is converted to hydrogen sulfide and will be captured by processes presently used in the chemical industry. In some methods, the sulfur will be extracted in either a liquid or solid form that can be sold commercially.
