TWO:But he knew there was another disposition of events possible. She had told him yesterday that she was not sure whether she would work there that morning or not. All the week her hours in the office had been long, and she might spend the morning out of doors. He knew already that she loved the downs, and indeed it was she who had told him of this particular path which he was now taking as a favourite ramble of hers. Her brother almost invariably walked with her, and Keeling was quite innocent of contriving an accidental meeting with her alone. But somewhere floating about in his heart was the imagined possibility that she might be alone, and that he would meet{232} her. He did not expect to meet her at all, but he knew he would love to see her, either with Charles or without, swinging along on this warm windy morning in the freedom of the country air and the great open spaces. They would suit her.... But primarily it was not she in any way that he sought: he wanted open space, and this wonderful sense of spring with its white bowlings of cloud along the blue, and its upthrusting of young grass. He wanted it untrammelled and wild, the tended daffodils and the buildings of birds so near house walls was not part of his mood.

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:Mrs Goodford took no notice whatever of this. It is likely that her quick little eye had intercepted the telegraphic suggestion of champagne, and that she was justly irritated at her son-in-la{25}ws rejection of it. She laid herself out to be more markedly disagreeable than usual.The conversation was cut short by the call to dinner, a call that has suppressed many a touch of sentiment before now, on land as well as on the water.
  • 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:No, I must turn too, he said. Maynt I walk with you?

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

THREE:They did not get far from Odiwara before it was necessary to leave the jin-riki-shas and take to the cangos. These were found waiting for them where the road ended and the footpath began, and the boys were delighted at the change from the one mode of conveyance to the other. Doctor Bronson did not seem to share their enthusiasm, as he had been in a cango before and did not care for additional experience. He said that cango travelling was very much like eating crowa man might do it if he tried, but he was not very likely to "hanker after it."And Im told she has a nice little fortune of her own, continued Mrs Goodford. Trust a Keeling for that. Ah, dear me, yes: there are some that go up in the world and some that go down, and I never heard that the Keelings were among those that go down.
  • 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:They mounted the steep ascent down which he had come a few minutes before. The wind was at their backs, ruthlessly blowing them towards Bracebridge.
