TWO:Isabella grew pale as she listened; for by some strange instinct she had so connected Holgrave with the abduction of her child, that his flight seemed now to have wrested from her her last hope.

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

THREE:"A parson!" cried Pete.
  • 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:As soon as the supper was over, Reuben still munching bread and bacon went up to his wife's room. The sunlight was gone, but the sky was blood-red behind Boarzell's hulk, and a flushed afterglow hung on the ceiling and moved slowly like a fire over the bed. The corners of the room, the shadows cast by the furniture, were black and smoky. On Naomi's face, on her body[Pg 114] outlined under the sheet, the lights crimsoned and smouldered. There was a strange fiery reflection in her eyes as she turned them to the door.He was still looking into her eyes, and she was visited by a terrible feeling that came to her sometimes and went as quicklythat he was not so mad as people thought.
