Process for dewatering coal slurries
Patent
·
OSTI ID:6371800
The invention concerns a method for optimization of the coal slurry dewatering process. Through a regulation of the fine grain content, it is possible to keep the filter cake at a constant level and thus to maximize the dewatering process. A separation of the slurry into a predominantly relatively fine grain fraction and a relatively coarse grain fraction, with the division point being between about 0.03 and 0.15 mm, is carried out, with a formation of a coal agglomerate from the fine grain fraction, and a dehydration of both the coarse grain fraction and the coal agglomerate from the fine grain fraction.
