TWO:[Pg 50]Her eyes danced; she leaned away and nodded. Then she drew nearer than before: "Dolls!" she murmured again;--"and pincushions!--and emeries!--and 'rats'! you know, for ladies' hair--and chignon-cushions!"

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:But the heedless throng of fashionables recked nothing of this. The Countess Lalage was their latest craze. Who she was or where she came from nobody knew nor cared. She was young and wonderfully beautiful in a dashing Southern way, her equipages were an amazement to the park; she must have been immensely rich, or she would never have entertained as she did. There must have been a Count Lalage at one time, for generally a pretty little girl rode with the Countess, and this child was her daughter. The Countess spoke casually of large South American concessions and silver mines, so that Oxford Street and Regent Street bowed down and worshipped her."There now!" exclaimed Mrs. Masters, hastily arranging an antimacassar on the back of a chair, "I won't tell you that, because, of course, I don't know."
  • 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:Arthur walked out to the wicket. His usual knee-shaking seemed less pronounced, and he felt more anxious about the Clockwork man than about himself. He paused as he drew near to him, and whispered in an earrather fearfully, for he dreaded a recurrence of the ear-flapping business. "The captain says will you run, please, when you're asked."

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

THREE:"Lieutenant, she guessed! She must have just put two and two together and guessed! Or else, Lieutenant,--"
  • 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:I shall be here till half-past one, if you want to ask me anything, he said, and shut the door between her little cabin and his big cool room. This door was heavily padded at the edges, so that the clack of the typewriter hardly reached him.
