TWO:The mystery was soon solved. The river was neither wide nor deep, and the men they saw waiting by the bank were porters who carried people across, and also carried merchandise. The stream was said to rise very rapidly, and owing to the nature of the bottom it was difficult to maintain a bridge there for any length of time. The porters took the party across very speedily; they carried the servants by what the boys called "pick-a-back," while Doctor Bronson and the boys were borne on chairs resting on poles, with six men to each chair. Some horses belonging to another party were led through the river at the same time, and evidently were not pleased with the bath they were receiving.

Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:"Papa tells us you are being sent off on courier duty to-night. What a heart-breaking thing is war! How full of cruel sepa'--"
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:"And she--ah, yes. I see; and I see, too, that in all she ever said or did or seemed, before, she never made herself such a treasure to be longed for and fought and lived for as in the way in which she--" He paused.Keeling pushed back his chair as he often did when he was disposed for a few minutes talk, putting a gap between himself and his business table. He gave her a smile and a long look.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:"'Tis the enemy, I think," he said, "but only scouts, I suppose."
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:His smile darkened. "I am your prisoner," he said, with a sudden splendid stateliness, and right then I guessed who he was.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
