TWO:Leona closed the door behind her with a snap. She was alert and vigorous as a general in action now. She passed downstairs swiftly but firmly, and into the morning room. One by one she snapped up the electric lights till the whole room was bathed in a golden glow.

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:In man there is nothing great but mind.

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

THREE:"Well, I fancy I can tell you more about it," Hetty went on. "Only you must not look so interested. Try and assume the idiotic expression of a lover on the stage. Last night I could not sleep. I have been terribly restless lately. I got up to fetch a book from the schoolroom, which is in the front at the top of the house. The blind was up, the window was not closed, so I looked out. The air was so cool that it did my head good. I was there about a quarter of an hour. I heard the noise of a door being closed and whispers on the pavement. Those people had come out of the corner house, two of them--a man and a woman."
  • 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:And you chew gum! snapped Sandy, unwilling to be left out of the suddenly developing third degree he had begun. Jeff made a further inspection, touched a bit of the dried gum curiously, stepped down and stood with a thoughtful face for a moment."I can't believe it," said Lady Rockingham. "Mr. Harcourt, are you quite clear and certain of your facts? Who told you?"

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