    Abstract: A coal separation unit for a gasification system includes a vessel having a top portion and a bottom portion, a first inlet configured to receive a feed stream including at least coal and ash from a grinding unit, a second inlet configured to receive a wash fluid stream, a first outlet configured to convey a low-ash feed stream, and a second outlet configured to convey an ash-rich stream. In operation, the feed stream is washed with the wash fluid stream in the separation unit to separate at least a portion of the ash from the coal. The separated ash settles to the bottom portion of the vessel and is conveyed via the second outlet as the ash-rich stream. The separated coal floats to the top portion of the vessel and is conveyed via the first outlet to a gasification unit as the low-ash feed stream.
