		<description><![CDATA[The waste heat is used internally to a great degree - A company I worked for as engineering manager was looking at the Lurgi Grate process in great detail just a couple of years back.



The Dakota Gasification plant is really interesting as the gasification section is one of the smallest (physically). The model shows this well - the US gov spent a couple of million dollars on the model back in the early 80&#039;s.



The plant produces natural gas, amines, sulfate fertilizers, argon, krypton, xenon and I forget what all else in tremendous volumes. CO2 is piped to oil fields in Canada to enhance production from old wells.



One big problem is the tremendous investment required for the overall complex - billions.



My visit there was very interesting to say the least! Hate the Bismark airport - big nuisance with some idiot from Northwest Airlines that I will never forget!]]></description>

		<description><![CDATA[Many thanks Susan for this interesting post !



I wonder if the US could use more renewables as natural gas prices go back up.



Since renewables are intermittent, providing the remaining electricity with a cleaner and lower carbon energy source like natural gas instead of coal sounds like a good idea.



Keep up the good work. Greeting from France ! ;)]]></description>

		<description><![CDATA[Susan, you&#039;re right...



In the name of progress we have forsaken things like the heat energy perceived as the &quot;waste&quot; heat.



We need to think smarter not harder - combined cycle is the name of the game!



That waste heat is perfect for creating super heated steam, in the case of a gasification plants, the leftovers can be reused via heat exchangers.]]></description>

		<description><![CDATA[Susan, the demand for raw coal may drop, and the price of natural gas may be low right now, in fact the cost of my local utilities natural gas has dropped 20%, but as soon as the price of the gas increases (again because it will) there will be a new demand for raw coal - how so?, gasification.



Each day the Dakota Gasification Company&#039;s Synfuels Plant converts approximately 18,000 tons of lignite coal into an average 145 million cubic feet of synthetic natural gas for home heating and electricity generation...



http://www.dakotagas.com/Gasification/Gasification_Process/index.html



Eastman Kodak gasifies ~ 1300 tons of coal per day for raw materials and energy.



Eastman marks 25 years in coal gasification.

There will always be some need for coal in one form or another.]]></description>
