Abstract
A coal upgrade plant includes: a dryer 1 that heats and dries coal before pyrolyzing the coal; a scrubber 32 that treats a carrier gas discharged from the dryer 1 while catching a desorbed component desorbed from the coal when the coal is dried by the dryer 1; a waste water treatment equipment 40 that treats waste water collected from the scrubber 32; and the scrubber 32 that uses recycled water treated in the waste water treatment equipment 40. Thus, water supplied to the coal upgrade plant from outside can be reduced as much as possible.
