TWO:Gregg swung round and sat on the couch. He lit a cigarette. He made no effort to conceal his sense of superior self-possession. The doctor took the cigarette that was proffered to him, and leaning forward tried to take a light from his companion. But his hand shook so violently that he could not manage the simple operation. In the end Gregg lit another match and held it with a steady hand.

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:"Would you object," said the Clockwork man, "to having all your difficulties solved for you?"
  • 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:"Law, you hain't!" cried Mrs. Wall, smiling back as she jounced. "If you air, the Majo's sisteh's got written awdehs fo' you."

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

THREE:I held them up and scowled from them to Harry, and we both laughed, so transparent was Gholson's purpose to get every one away from our patient who yearned to be near her. "One in front of each pistol," I said, so tying them; "but use the pistols first, I suppose.""Oh, they don't hurt us. We don't feel any pain or annoyance, only a dim sort of revolt, and even that can be adjusted. You see, the makers can ring the changes endlessly with us, and there isn't any kind of being, from a great philosopher to a character out of a book, that we can't be turned into by twisting a hand. It's all very wonderful, you know."
  • 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:Perhaps you would tell me something about him, he said."I met George Pauncefort in China years ago," said the Doctor, as they entered the hotel; "I wonder if he will recognize me."
