摘要:
A process for the prevention of the deposition of entrained soluble coal products from vaporous solvent recovered from a heavy fraction comprising insoluble coal products and some solvent and soluble coal products. The heavy fraction is produced in a coal deashing system employing solvent at elevated temperatures and pressures near the critical conditions of the solvent. The heavy fraction is reduced in pressure to form a mixture of ash concentrate and vaporous solvent together with entrained soluble coal products. This mixture then is turbulently admixed for at least 0.05 seconds to coalesce or condense the entrained soluble coal products upon the ash concentrate particles. The coalescence or condensation of at least a portion of the soluble coal products substantially prevents or minimizes deposition of the same in the solvent withdrawal conduit of subsequent vapor-solid separation apparatus. Alternatively, the mixture is introduced into a fluidized bed of ash concentrate. The entrained soluble coal products then coalesce or condense on the fluidized particles by contacting the same.
