    摘要： Sublimate vapors are recovered from gases in a heat-pipe exchanger system, operating alternately in a condensing mode and a melting mode, for condensing on the exchanger tube surfaces such sublimable vapors as phthalic anhydride, maleic anhydride, naphthalene and fatty acids from gases containing said vapors thereof during the condensing mode, and for melting out the accumulated sublimate solids during the melting mode. Multiple, such as two or more units may be used to provide continuous processing of the sublimate vapor-laden gas stream, at least one operating in the condensing mode while simultaneously at least one may operate in the alternate mode. The cooling of opposite heat-pipe exchanger ends to recover sublimate solids is economical and efficient with ambient air, either alone or with some warm recycle exchanger air to adjust the cooling temperature; and the heating to melt out the accumulated solids is effective with heated air or hot waste gases, such as combustion gases, preferably by incineration of residual sublimate tail gas from which the sublimate was condensed, or other hot combustion gases, but other sources of heating the air or gases may be optionally substituted. Important advantage is present in superior heat exchange efficiency using the heat-pipe exchanger for this service, in the ease of switching from heating to cooling of such exchangers for alternate operation in both condensing and melting modes, in the elimination of intermediary heat transfer media and the separate auxiliary equipment required for the heating and cooling cycles, in the utilization of waste heat from combustion gases, and in the great economy for sublimate storage tank vent condensers through elimination of both cooling water and steam requirements.

    摘要： A method is provided for continuous removal of polychlorinated biphenyl compounds (PCB) from oil contaminated therewith, comprising the steps of continuously extracting PCB compounds from contaminated oil with a PCB-selective solvent in the stripping section of a multistage extraction zone, partially distilling the extract from the extraction zone in a distillation zone, cooling and separating the bottom residue into a solvent phase and an oil/PCB phase, continuously recycling a major portion of the oil/PCB phase as extract reflux to the enriching section of the extraction zone where PCB compounds are extracted from the recycled portion by the solvent phase produced in the stripping section of the extraction zone to increase the PCB content of the extract, and withdrawing a minor portion of the oil/PCB phase from the separation step as a disposable PCB residue.

    摘要： Phthalic anhydride is recovered from gases in a multiple heat-pipe exchanger system, one or more for condensing phthalic anhydride from gases containing vapors thereof and one or more simultaneously melting out the condensed phthalic anhydride solids, the exchangers being switched in alternate cycles to melt out from the surfaces of the exchanger tube ends on which the phthalic anhydride solids were first accumulated, and to condense phthalic anhydride solids in the exchanger or exchangers from which the phthalic anhydride was cleared by melting out. The cooling of opposite heat-pipe exchanger ends to recover phthalic anhydride is economical and efficient with ambient air, either alone or with some warm recycle exchanger air to adjust the cooling temperature; and the heating to melt out accumulated phthalic anhydride is effected with hot gases, such as combustion gases, preferably by incineration of residual phthalic anhydride tail gas from which the phthalic anhydride was condensed, or other hot combustion gases, but other sources of heating the air or gases may be optionally substituted. Important advantage is present in superior heat exchange efficiency using the heat-pipe exchanger for this service, in the ready switching from heating to cooling of such exchangers for alternate operation in both condensing and melting out modes, in the elimination of intermediary heat transfer media and the separate auxiliary equipment required for the heating and cooling cycles, in the utilization of waste heat from combustion gases, and in the great economy for phthalic anhydride storage tank vent condensers through elimination of both cooling water and steam requirements.

    摘要： A feeder for discharging a load of material includes a hopper, a swing arm pivoting between raised and lowered positions in the hopper, and a ram mounted on the free end of the swing arm. The ram is moved by the swing arm back and forth on a curved floor in a trapezoidally shaped trough underneath the hopper to push material in the trough out of the hopper through a discharge outlet. A shutoff valve at the discharge outlet prevents backflow of discharged material into the trough.
