TWO:He told her that he was going to operate at once, to remove the ball and the shattered bone, but that she might come if she wished. His disapproval was marked, but she went with him, nevertheless, and sat watching while he picked and probed at the wound.

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:The Reverend Taylor sat in silence for a time, reflecting. Then he broke forth again, a little querulously. "What in thunderation do they dine at such an hour for?" Cairness explained that it was an English custom to call supper dinner, and to have it very late.

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

THREE:He went on the next day with his scouts, and eventually joined Landor in the field. Landor was much the same as ever, only more gray and rather more deeply lined. Perhaps he was more taciturn, too, for beyond necessary orders he threw not one word to the chief of scouts. Cairness could understand that the sight of himself was naturally an exasperation, and in some manner a reproach, too. He was sorry that he had been thrown with this command, but, since he was, it was better that Landor should behave as he was doing. An assumption of friendliness would have been a mockery, and to some extent an ignoble one.
  • 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:The Reverend Taylor and Cairness had managed, with a good deal of adroitness, to keep the identity of their patient a secret. Stone was consequently not at all prepared to have her stride in upon him. But he was not a man to be caught exhibiting emotions. The surprise which he showed and expressed was of a perfectly frank and civil, even of a somewhat pleased, sort. He called her "my dear madam," and placed a chair for her. She sat in it under protest. He kept up the social aspect of it all for quite five minutes, but sociability implies conversation, and Cairness and the minister were silent. So was the woman—rigidly.
