TWO:And there were no elders any more. There were neither elders nor masters: there was only Cadnan, and Daraand, somewhere, Marvor and the group he had spoken of. Cadnan peered round, but he saw no one. There were small new sounds, and those were frightening, but they were so tinyrustles, squeaks, no morethat Cadnan could not feel greatly frightened by them.

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:"Well, Gabe, go down to the branch and git some more water, quick as you kin move them stumps o' your'n. Give the men all they want to drink, and then pour some on their wounds. Then go there and cut some o' them pawpaws, and peel their bark, to make a litter to carry your pardner back to the mill. Boys, look around for guns. Smash all you kin find on that rock there, so they won't be of no more use. Bust the locks good, and bend the barrels. Save two to make the handles of the litter.""The Surgeon ought to see you at once, Alf," interjected Shorty. "Here comes one of 'em now. Doctor, will you please look at this boy."

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

THREE:The man looked on Shorty's display of wealth with lack-luster eyes, but his wife was fascinated, and quickly closed up a deal which conveyed to Shorty all the food that they had. Just as Shorty had completed payment, there came a shot from little Pete's rifle, and the next instant that youth appeared at the edge of the cornpatch extending up hill from the cabin, hatless, and yelling at the top of his voice. Shorty and the others picked up their guns and took position behind the trees.
  • 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:

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