REDEFINING REFINING BY BRIAN SALGADO CLEANER CLEAN COAL F GREAT RIVER ENERGY’S COAL CREEK STATION POWER PLANT IS SHOWING THE WORLD HOW TO ‘DRYFINE’ COAL. rom the outside, Great River Energy’s Coal Creek Station might look like a run-of-the-mill coal-fueled power plant. However, the Underwood, N.D.based facility is basking in the industry spotlight as refiners from around the world attempt to apply Coal Creek Station’s patented “DryFining” process to their own plants. Senior Principal Engineer Charlie Bullinger and his team at Coal Creek Station began researching a process in 1997 to make the lignite coal used at the plant cleaner and more efficient. The solution born from this research was to utilize the waste heat generated by Coal Creek Station to dry the lignite. Lignite coal is an ideal fuel source for this application, according to Bullinger, because of it has a higher water content than other types of coal. By reducing the amount of water in the fuel through a drying process, Coal Creek Station is able to increase the energy density and value of the coal; reduce the total volume of flue gases that must be handled throughout the system; and improve the plant’s overall efficiency. In 2000 and 2001, The Falkirk Mining Co. – which supplies Coal Creek Station its lignite coal – Great River Energy and The Coteau Properties Co. launched the Lignite Fuel Enhancement Incremental Moisture Reduction Project. Through this initiative, small-scale tests displayed the possibility of drying lignite incrementally with relatively low-temperature air. These positive results prompted the WINTER 2011 6 | EXPLORATION-PROCESSING.COM http://www.EXPLORATION-PROCESSING.COM
