<p>GRANULATION PROCESS Sorbent, calcium sulfate dihydrate-containing granules are produced by dispersing particulate calcium sulfate hemihydrate into a generally helical turbulent gas stream, contacting the dispersed hemihydrate particles with an aqueous binder in an amount sufficient to wet and agglomerate the particles and to initiate hydration of the hemihydrate to the corresponding dihydrate, and mechanically agitating the resulting dispersion so as to pack the wetted particles into granules while hydration takes place. Thereafter the produced granules are recovered from the gas stream and, if necessary, dried.</p> |
