Abstract

1533852 Wet separation of coal SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 9 Feb 1976 [10 Feb 1975 31 Oct 1975] 5482/75 and 45156/75 Heading B2H [Also in Division C5] Coal particles in a coal/water slurry are separated by (a) supplying the slurry to a separator 22 wherein the larger coal particles together with a relatively small quantity of water are separated from the slurry, leaving a second slurry comprising the smaller coal particles and a relative large quantity of water (b) withdrawing the larger coal particles and a small quantity of water as product (c) passing the second slurry to an agglomeration device 26 (d) introducing a binder and the second slurry into the agglomeration device so that coal agglomerates are formed (e) separating the agglomerates from the water (35) and (f) withdrawing the agglomerates as a product. The slurry may contain fine free ash particles and these remain with the smaller coal particles in step (a) and are separated from the agglomerates in the water in step (e). The binder may be hydrocarbon e.g. gas oil.
