TWO:Well, after what the Club has done to-day, he said, there is no telling whom they would blackball. But certainly I should have been, at one time, very happy to propose him.

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: "Then we have had glimpses of the way the people spin cotton, and perform other work in the manufacturing line. Their apparatus is very[Pg 299] simple, and it is rather surprising than otherwise that they can accomplish so much with so little machinery. Then we have walked about the streets, and several times we have had close escapes from being run over by some of the carts that were carrying heavy loads. With two men to push them, and two pulling at the same time, they will move loads that would be no small matter for a pair of horses. They keep up a great shouting, and at first it puzzles you to know why they do it until you remember that it is desirable they should all pull together. You can hear them a long way off, and if you get in their way it is your own fault, as it was ours.The note of patriotism righted me and I looked a third time. The one art of dress worth knowing in '63 was to slight its fashions without offending them, and this pretty gift I had marked all day in the Harpers. But never have I seen it half so successful as in the veiled horsewoman illumined by the side-lights of those burning fence-rails. The white apparition at the veranda's edge gleamed in my mind, yet swiftly faded out, and a new fascination, more sudden than worthy heaved at my heart. Then the fire was behind us and we were in the deep night.
  • 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:"Undoubtedly, as nothing has ever been heard from them. They did not leave any history of themselves on the island, or, at any rate, none was ever found."The captain went on to say that there were many pirates in the waters around Canton, and all along the southern coast. The government tries to suppress them, but it is not easy to do so, and hardly a day passes without the report of a robbery somewhere. All trading-junks are obliged to go heavily armed, and out of this fact comes a great deal of the piracy, as a junk may be a peaceful trader at one o'clock, a pirate at two, and a peaceful trader again at three. It takes very little to induce a Chinese captain to turn pirate when he sees a rich prize before him, and he has no trouble in winning over his crew. It is impossible to distinguish the pirate from the trader; and as the coast is seamed with island passages and indented with bays, it is easy for a junk to escape after she has committed a robbery.

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

  • 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:The landlord assured him that there was no peculiarity of his costume that he could point out as any such indication.

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