TWO:He was sorry she was going, but made no attempt to detain her, and presently she was walking back along the still sunny road with her brother."But how did you come by these?" questioned Gregg, who was still holding the hat and wig.

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:Camille declared she did not and would not believe there had been any fault with any one, anywhere, and especially with Mr. Gholson, and I liked Lieutenant Helm less than ever, noticing anew the unaccountable freedom with which Camille seemed to think herself entitled to rebuke him. "Oh, I'm in your power," he cried to her, "and I'll call him a spotless giraffe if you want me to! that's what he is; I've always thought so!" The spring-wagon was taking the left fork and he cantered ahead to begin his good-byes there and save her for the last. When he made his adieu to her he said, "Won't you let Mr. Smith halt here with me a few moments? I want to speak of one or two matters that--"
  • 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: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."It is because the temples belong to different forms of religion," the Doctor answered. "Those where you saw the statues of Buddha are Buddhist in their faith and form of worship, while the rest are of another kind which is called Shinto."

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

THREE:
  • 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:Poor Keelings head whirled: a moment ago his wife had said that the two were great friends only on the spiritual plane, now she was saying precisely what she had begun by contradicting. He was satisfied, however, that he had her true opinion at last. It did not appear to him to be{149} worth anything, but there it was. He got up.
