  • Patent number: 4209911
    Abstract: This invention relates to a process and apparatus for drying moisture-containing particulate materials. The process comprises feeding the particulates to a drying vessel containing therein a hydrocarbon liquid maintained at a temperature sufficiently high to rapidly evaporate the moisture; stirring the articulate-liquid slurry in the vessel so as to maintain particle flow therein; feeding a hot hydrocarbon liquid to the vessel; heating the vessel wall above the liquid level to a temperature above the slurry temperature to prevent foaming; removing from the vessel an overhead vapor product; and condensing the vapor product to recover water and hydrocarbon liquid. An apparatus useful for carrying out the above-mentioned process is also claimed.
