TWO:Not many years ago, China and Japan were regarded as among the barbarous nations. The rest of the world knew comparatively little about their peoples, and, on the other hand, the inhabitants of those countries had only a slight knowledge of Europe and America. To-day the situation is greatly changed; China and Japan are holding intimate relations with us and with Europe, and there is every prospect that the acquaintance between the East and the West will increase as the years roll on. There is a general desire for information concerning the people of the Far East, and it is especially strong among the youths of America.

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:"I'm afraid your explanation won't hold water," he rejoined. "I can't bring myself not to believe in what I saw. You see, all my life I have been trying to believe in miracles, in manifestations. I have always said that if only we could bring ourselves to accept what is not obvious. My best sermons have been upon[Pg 129] that subject: of the desirability of getting ourselves into the receptive state. Sometimes the Vicar has objected. He seemed to think I was piling it on deliberately. But I assure you, Doctor Allingham, that I have always wanted to believeand, in this case, it was only my infirmity and my unfortunate nervousness that led me to lose such an opportunity."And theres a word to me! she said. Fancy telling me that my mother detests my husband. Thats an un-Christian thing to say about anybody.

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:Slowly, with a wildly beating heart, the Doctor inserted a trembling finger among the interstices of those multitudinous stops and hands, and as slowly withdrew it again. He could not do this thing. For one thing, his finger was too large. It was a ridiculously clumsy instrument for so fine a purpose. What if he failed? Pressed a knob too hard or set a hand spinning in the wrong direction? The least blunderAnd so he said nothing. They remained by the stile, courting each other and the silent on-coming of night. They were very ordinary lovers, and behaved just exactly in the same way as other people in the same condition. They kissed at intervals and examined each other's faces with portentous gravity and microscopic care. Leaning against the stile, they were frequently interrupted by pedestrians, some of whom took special care to light their pipes as they passed. But the disturbance scarcely affected them. Being lovers, they belonged to each other; and the world about them also belonged to them, and seemed to fashion its laws in accordance with their desires. They would not have offered you twopence for a reformed House of Commons or an enlightened civilisation.
