Coal Gasification
Gasification Technology:
Coal gasification has been a technology that has come
and gone in many different manners through out history.
Coal gas was used to light cities from New York to San
Francisco during the Victorian era. Modern day Atlanta’s
power company is still called the Atlanta Gas Light
Company. Coal was heated to a
temperature significant enough to give off enough
natural gas to light the city. The gas was captured then
compressed and piped to gas lights in the lighted
sections of the city. During this time the technology
was crude. The process produced a tarry by-product we call “coal
tar”. Huge waste pits are located in and around the city
and other Georgia cities, such as Savannah and Athens.
The process was simple, but effective. Gasification has
been in commercial use for more than fifty years as a
process technology for the refining, chemical, and power
industries.
In 1999 the first World Gasification Survey was
conducted by the firm of SFA Pacific, Inc. with support
from the U.S. Department of Energy, and in cooperation
with the member companies of the Gasification
Technologies Council. The survey identified and gathered
information on 160 commercial gasification plants in
operation, under construction, or in planning and design
stages in twenty-eight countries in North and South
America, Europe, Asia, Africa and Australia.
The total daily capacity of these facilities when in
operation will be close to 430 million normal cubic meters
of synthesis gas (syngas). This is the energy equivalent
of more than 770,000 barrels of oil per day. [Note: one
million normal cubic meters of syngas is the equivalent
of 37.3 million standard cubic feet, or 10.4 billion
Btu’s.]
Our ultra high temperature plasma-arc technology (1650º
C or 3002 º F) has the capability to produce synthetic
natural gas (SNG) in an oxygen starved atmosphere. This
technology has been thoroughly tested and is now in
production in many locations as a primary source of
energy for electricity generation, a reliable method of
vitrifying the toxic constituents in contaminated soils
and high sulfur fossil fuel feed stocks, i.e. High
sulfur crude oils, coal, slaughterhouse by-products,
ranching and farm waste and many other waste oils. The
US government has studied this technology and has shown
through millions of dollars of research and pilot
studies that not only is the process effective, but also
very economical in many respects. Several government
websites show the United States Initiatives for 2005
thru 2015 to mitigate the fossil fuel demand by
diversification;
