TWO:"Who told you he was?" she asked.

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:Taylor nodded."No," he said, "I wouldn't like you to, and she wouldn't want it, I reckon." He dropped back into his usual speech. "She ain't any repentant sinner, by a good deal. But as Cairness wants me to keep an eye on her, and as she's sick, I wish you to let her stay in the house, and not to make a rumpus about it. If you really don't like to go near her, though," he finished, "I'll tell you what I'll do, I'll take her in her food myself, and nurse can clean out her room."
  • 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:"What is this?" he shouted, grabbing at a halter-shank and clinging to it until a knife slashed down on his wrist.

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

THREE:"Cheese that cussing, do you hear?" he ordered.In pursuance of which the resolute and courageous men arose at the cry of their bleeding land. They have gone down to history (to such history as deigns to concern itself with the reclaiming of the plains of the wilderness, in area an empire of itself) as the Tombstone Toughs.
  • 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).
