Abstract
A coal upgrade plant includes a dryer 1 that heats and dries coal before pyrolyzing the coal, and 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. The coal upgrade plant further includes a carrier gas circulation path 22 that guides the carrier gas treated by the scrubber 32 to the dryer 1. A cyclone 28 is also provided on the upstream side of the scrubber 32. Thus, mercury and/or mercury-based substances generated in the dryer 1 can be removed.
