摘要： A process for separating or stripping lighter components from a heavier hydrocarbon feedstock contaminated with or otherwise including light components. The separation is accomplished by introducing the feedstock into a column and allowing the feedstock to flow through the column, contacting a first stripping medium and a second stripping medium. The first stripping medium entrains the lighter components. The second stripping medium entrains the first stripping medium and any lighter components remaining in the feedstock. Preferred first stripping media include hydrogen, methane, propane, and other inert gas and preferred second stripping media include nitrogen and other inert gas.

摘要： A thermally-integrated extractive distillation process for recovering anhydrous ethanol from fermentation or synthetic feedstocks has a distillation train of four columns. Two columns are preconcentrators operated in parallel. The remaining columns are an extractive distillation dehydrating tower, and an entrainer-recovery column. The two preconcentrators and the dehydrating tower are operated at three successively increasing pressures so that the condensing vapors of the overhead product of the dehydrating tower supply the necessary heat to the reboiler of the intermediate-pressure preconcentrator. The overhead vapors of this preconcentrator are, in turn, used to supply the required heat to the reboiler of the lowest-pressure preconcentrator. The bottom product from each preconcentrator is used to preheat the dilute feed. Additional energy savings are accomplished by the appropriate heat exchange between the various feeds, overheads, and bottoms.

摘要： A distillation apparatus including a pair of vertical lower vessels each open at its upper end, and a pair of elongate upper vessels each having an open lower end, slidably mounted in a respective one of the lower vessels. A heat exchanger is mounted in each of the upper vessels, with the upper end of one upper vessel being connected to the inlet of the heat exchanger in the other vessel, and vice versa. A reciprocating drive mechanism drives the two upper vessels up and down in opposite directions so as to simultaneously effect compression in the space above the liquid level in the downwardly moving vessel while expanding the space above the liquid in the other vessel, driving vapor from the downwardly moving vessel into the heat exchanger in the other vessel, where it condenses.

摘要： A volatile component is separated from a mixture by vaporization in an evaporator and condensation in a condenser. The vapor is transported by a carrier gas that is circulated in and between the evaporator and the condenser. A flow of a liquid is circulated in subsequent heat transfer steps from contact with the mixture via a cooler, via contact with the carrier gas in the condenser, via a heater, and back to contact with the mixture.

摘要： A process is disclosed for the separation of aromates from hydrocarbon mixtures of optional aromate content through extractive distillation using N-substituted morpholine displaying substituents having no more than 7 C-atoms as selective solvent. Part of the solvent is delivered to the uppermost plate of the extractive distillation column and the remainder of the solvent, preferably amounting to between 10 and 40% by weight, is introduced into the extractive distillation column in at least two partial streams onto plates above the inlet for the hydrocarbon mixture. The temperature of the respective solvent partial streams is adjusted to neither exceed the temperature of the corresponding delivery plates nor fall below this temperature by more than 10.degree. C.

摘要： An improved distillation method and apparatus are provided for recovering hydrous ethanol from fermentation or synthetic feedstocks. Substantial energy savings are realized by utilizing a pair of stripper-rectifier towers in which overhead vapors from one tower operating at a higher pressure supply the heat required for the other tower operating at a lower pressure and by preheating the feedstock in multiple heat exchange steps. The feedstock is split into two portions of unequal size, the larger portion being supplied to the higher pressure tower and the smaller portion to the lower pressure tower.

摘要： The invention relates to a method and a device for the production of pure steam. A falling-film evaporator is used. Of the water-steam mixture leaving the evaporator unit, part of the water is collected at the bottom of the device, and a fraction mainly consisting of steam enters a rising spiral channel for the separation of impurities. In the periphery of the spiral channel apertures are provided for separating impurity-containing droplets, which condense on a surface outside the apertures. The liquid formed is removed from the device. The water phase collected at the bottom enters a recycle line connected to the feed end of the evaporator unit. Feed water is supplied to the recycle line to compensate for pure steam consumption.
