TWO:He hesitated with a momentary compunction. She must have suffered pretty well for her sins already; her work-cut, knotty hands and her haggard face and the bend of her erstwhile too straight shoulders—all showed that plainly enough. It were not gallant; it might even be said to be cruel to worry her. But he remembered the dead Englishwoman, with her babies, stiff and dead, too, beside her on the floor of the charred cabin up among the mountains, and his heart was hardened.She took it and looked from it to him, questioningly. "What is this?" she asked.

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:
  • 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:If you take even a good-humored puppy of a savage breed and tie him to a kennel so that all his natural energy strikes in; if you feed him upon raw meat, when you feed him at all, but half starve him for the most part; and if you tantalize and goad him whenever you are in search of a pastime, he is more than likely to become a dangerous beast when he grows up. He is then a menace to the public, so you have but one course left—to take him out and shoot him.[Pg 329]

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

THREE:"So?" said Cairness, with the appearance of stolidity he invariably assumed to cover disappointment or any sort of approach to emotion. "Where's she gone to?""You know that I love you?" he said unevenly.
  • 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:"Still," said Felipa, too quietly, "I would rather be the daughter of a drunken private and a Mescalero squaw than the wife of a coward and sneak."It was.
