TWO:Gregg sat up in his chair and became more serious. Allingham fidgeted without actually interrupting.

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:"Oh, by Regulations, I suppose, I ought to turn one of them over to Major Harper. I wish it were to you, Lieutenant; I'd keep my own--he'll be all right in a day or two--and give you Captain Jewett's."
  • 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:They were off at an early hour, and, as before, their route was along the Tokaido. The provisions and other things had been sent on ahead during the night, and they did not see them until they came to the place where they were to sleep. They took a light meal before starting from Yokohama, and found a substantial breakfast waiting for them at Totsooka. Their host was a famous character in the Eastan English actor who had drifted through China and Japan, and finally settled down here as a hotel-keeper.

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

THREE:"That's my conviction," he gasped out, too excited and breathless for further speech.
  • 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:Arthur swallowed several times in rapid succession. His mind relapsed into a curious state of blankness. For some minutes he was not aware of any thinking processes at all. He began to feel dizzy and faint, from sheer bewilderment. And then the idea of escape crept into his consciousness. He moved one foot, intending to walk away. But the strange figure suddenly lifted up a hand, with an abrupt, jerky movement, like a signal jumping up. He said "nine and ninepence" three times very slowly and solemnly, and flapped his right ear twice. In spite of his confusion, Arthur could not help noticing the peculiar and awful synchronisation of these movements. At any rate, they seemed to help this unfortunate individual out of his diffi[Pg 13]culties. Still holding a hand upright, he achieved his first complete sentence."I don't believe you! I don't believe you ever had cause for one!" She laid a hand again upon mine.
