In other coal-related industries, such as coal mining [6,7] and coal bed methane (CBM) production [8–10], the treatment of underground or produced water is also of great significance.
2013-1-1 · Gasification-based plants with coal-CO 2 slurry feed are predicted to be more efficient than those with coal-water slurry feed. This is particularly true for high moisture, low rank coal such as lignite. Nevertheless, preparation of the CO 2 slurry is challenging and the losses associated with this process have not been accounted for in previous analyses.
