TWO:"About five in the morning. But we didn't see her then; she shut herself up and wrote and wrote and wrote! They say she runs the most daring risks! And they say she's so wise in finding out what the Yankees are going to do and why they're going to do it, that they'd be nearly as glad to catch her as to catch Lieutenant Ferry! Didn't you know? Ah, you knew!" She attempted a reproachful glance, but exhaled happiness like a fragrance. I asked how she had heard these things.

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:Her gentle irruption found me standing almost on the spot where she had stood two evenings before and said good-bye to me. From this point a path led to the rear of the house, where within a light paling fence bloomed a garden. She gave us a blithe good-morning as she passed, descended the two or three side steps, and tripped toward the garden gate, a wee affair which she might have lifted off its hinges with one thumb. I saw her try its latch two or three times and then turn back discomfited because the loose frame had sagged a trifle and needed to be raised half an inch. I did not understand the helplessness of girls as well then as I do now; I ran and opened the gate; and when I shut it again she and I were alone inside.
  • 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:"My God! she shall not!" I cried, and whirled about and galloped back.

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

THREE:A GRASS OVERCOAT. A GRASS OVERCOAT.
  • 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 Clockwork man shook his head slowly from side to side. "No children. No lovenothing but going on for ever, spinning in infinite space and knowledge."
