Latest Patents

Heavin holds a patent for a process that blends coal with a water immiscible liquid. This continuous process produces a uniform, pumpable slurry. The method involves the continuous feeding of pulverized raw feed coal and a coal-derived, water immiscible liquid into a blending zone. In this zone, coal particles and liquid are intimately mixed to form a first slurry. This first slurry is then withdrawn and mixed with a hot slurry to create the final pumpable slurry. A portion of this slurry is recycled back to the blending zone for further mixing with the feed coal.
