<DIV>I understand there are mines that have caught fire underground by
accident in the 1950's and are still burning with the oxygen being
produced by FT reactions at the seat of the fire.<BR>GF</DIV>
<DIV> </DIV>
<DIV># Very true!! It is easy to set a mine fire, under the right conditions.
There is no question that FT reactions work, and there is no question that
such accidental underground coalfield fires have occurred in coalfields that
have been mined. From what I can see, (and please correct me if I am
wrong):</DIV>
<DIV> </DIV>
<DIV>1: Such accidental underground coalfield fires are uncontrollable.</DIV>
<DIV>2: Such accidental underground coalfield fires can cause very significant
"surface damage", in terms of subsidence, or gas emanations that can make
nearby communities uninhabitable<BR>3: Such accidental underground coalfield
fires do not produce a consistent gas, of value either for combustion in a
process, or for utiligation in a process.</DIV>
<DIV>4: Such accidental underground coalfield fires are generally considered
to be a disaster in the area where they occur.</DIV>
<DIV>5: Such accidental underground coalfield fires have never been used to
economic advantage</DIV>
<DIV>6: Such accidental underground coalfield fires are totally uncomparable
to "underground gasification projects intended to produce a fuel gas or
synthesis gas for economic benefit."</DIV>
<DIV>7: The Swan Hills Website contains a number of misleading statements
that seem to infer that their proposed project is equivalent to
"gasification", and that the relatively long history of
"gasification" can be used to show there project is technically feasible.
For example, at <A
href="http://swanhills-synfuels.com/iscg/overview/ we see: ">http://swanhills-synfuels.com/iscg/overview/
we see: </A></DIV>
<DIV>Gasification History: Gasification was first developed in the 1800s and
has been used commercially throughout the world for more than 100 years. A
variety of industries have utilized the technology including chemical
production, fertilizer manufacturing, and electrical power generation. Today,
the majority of the operating gasification plants worldwide are surface
gasification plants designed to produce chemicals, fuels, electricity, and
fertilizers.</DIV>
<DIV> </DIV>
<DIV>It then goes on to equate "Gasification" with "In-Situ Coal
Gasification " (ISCG)) in a misleading manner:</DIV>
<DIV>"<FONT size=2>How does Gasification work? Feedstock (for ISCG it is deep
coal) is exposed to high temperature and high pressure. In the presence of
steam at these conditions a series of chemical reactions occur which convert
the feedstock into syngas."</FONT></DIV>
<DIV>This would tend to suggest that the gas product from ISGC is equivalent
to the quality and production from a "surface gasification plant." The
Websiteite seems to gloss over the important differences, and seems to
overlook technical challenges that lie ahead for them. The Website contains a
number of statements which could be termed "forward looking."</DIV>

<DIV>What happens to the chlorine component in the underground
reaction.<BR>when using salt water. Chlorine is really unfriendly to metals
including stainless steel. </DIV>
<DIV>what sort of conduit is to be used for conducting the hot product
to the surface for refinement?</DIV>
<DIV> </DIV>
<DIV># Very gfood question!! The presence of chlorine in a starved oxygen
combustion environment is likely to generate an environmental disaster, with
the chlorinated hydrocarbons that that will almost certainly result.</DIV>
<DIV> </DIV>
<DIV># Underground gasification of coal is a really neat concept, but as far
as I know it doesn't work. See: </DIV>
<DIV><A href="http://en.wikipedia.org/wiki/Underground_coal_gasification"
target=_blank>http://en.wikipedia.org/wiki/Underground_coal_gasification</A> Many
people in many places have spent many dollars trying to get it to work.
After many tests, there does not appear to be a single commercially
successful Underground Coal Gasification project now, or in the past.</DIV>
<DIV> </DIV>
<DIV># See their Website at <A href="http://swanhills-synfuels.com/"
target=_blank>http://swanhills-synfuels.com/</A> On their FAQ page, <A
href="http://swanhills-synfuels.com/iscg/faq/"
target=_blank>http://swanhills-synfuels.com/iscg/faq/</A>, they state:
</DIV>
<DIV>"Gasification can compete effectively in high-cost energy
environments." This seems to say a lot.</DIV>

gasification plants designed to produce chemicals, fuels, electricity, and
fertilizers.</FONT></DIV>
<H2><FONT size=2>Gasification Market</FONT></H2>
<DIV><FONT size=2>As of 2008, there were 420 gasifiers at 140 facilities in
operation globally, the majority of these being surface gasification plants
(source – GTC). World gasification capacity is projected to grow by more
than 70% by 2015 with much of the growth occurring in Asia (source – GTC). A
number of factors contribute to a growing interest in gasification,
including volatile oil and natural gas prices, more stringent environmental
regulations, and a growing consensus that CO<SUB>2</SUB> management should
be required in power generation and energy production.</FONT></DIV>
<H2><FONT size=2>How does Gasification work?</FONT></H2>
<DIV><FONT size=2>Feedstock (for ISCG it is deep coal) is exposed to high
temperature and high pressure. In the presence of steam at these conditions
a series of chemical reactions occur which convert the feedstock into
syngas.</FONT></DIV>
<DIV><FONT size=2>In the case of ISCG, this chemical conversion of the deep
coal happens in place in its original seam. The resultant syngas created
consists primarily of hydrogen, methane, carbon dioxide, and carbon
monoxide.</FONT></DIV>
<DIV><FONT size=2>To create this chemical conversion, two wells are drilled
into the deep coal seam. A horizontal injection well is used to introduce
oxygen and water into the seam; the oxygen supports a limited and controlled
amount of combustion, raising the temperature of the coal and boiling the
water to generate steam.</FONT></DIV>
<DIV><FONT size=2>The naturally existing deep underground pressure, along
with the elevated coal temperature and the presence of steam, together form
the right conditions to gasify the coal. The vertical production well is
used to conduct the raw syngas to the surface. Char and ash, which are
remnants of the original coal, remain deep underground.</FONT></DIV>

<DIV><FONT size=2>The coal seam for ISCG development at the Swan Hills
Synfuels site is 1400 m beneath the surface, approximately 800 m below the
Base of Groundwater Protection (depth limit of fresh groundwater – below
this depth, groundwater is saline), eliminating potential for fresh
groundwater contamination. Saline water is used for injection into the coal
seam through the horizontal well, virtually eliminating the need for fresh
water in the ISCG process. </FONT></DIV></SPAN></SPAN></FONT></DIV></DIV>
