TWO:Felipa held out her hand and showed a little brown bird that struggled feebly. She explained that its leg was broken, and he drew back instinctively. There was not a trace of softness or pity in her sweet voice. Then he took the bird in his own big hand and asked her how it had happened. "I did it with an arrow," said Diana, unslinging her quiver, which was a barbaric affair of mountain-lion skin, red flannel, and beads.

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:Chapter 10
  • 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 got his hat. It was still a silk one, but new, and without holes. They went over to the false front board structure which was Stone's office. It appeared from the newspaper man's greeting that it was a case of the meeting of prominent citizens. Taylor presented Cairness, with the elegant, rhetorical flourishes he was capable of when he chose. "He is a friend of mine," he added, "and anything that you can do for him will be appreciated, you sabe?—" Stone did understand, and Taylor left them alone together.

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:The parson said that he could not. "Lawton ain't any use for me. I guess it's because he remembers me, that's why. He'll remember you, too."

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
