TWO:"That's it. For the present we have to sit here in the passage with the kitchen door open and watch for the faint gleam of light in the courtyard. It is safe to have a light there because there are blank walls on either side. I think, I rather think, that I am going to astonish you presently."

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:"Not? Oh! they are sure to do it. All the villages are burning already. The smoke suffocates us here. In Bressoux there is not a house left standing, and in other villages all civilians have been killed, men, women, and children. Not even the tiniest babies escaped.... Oh!... and now it is Lige's turn!""I was quite certain of the fact when I looked for it. And all the time this Corner House tragedy was being enacted exactly as I should have written it. There were other complications, of course, but the plot was the same."
  • 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:The woman reached up a long white hand, and taking the bulb of the swinging electric light in her grasp desperately, crushed it to pieces. Then there was swift darkness again and the rush of flying feet.

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

THREE:They had lured him there, and he had come with his eyes open. He cursed his folly. But then he had been hiding, and his money was gone. It seemed like a wonderful slice of luck to find Ghetti in London. And behold there was no Ghetti at all, only this trap and the knowledge that his time was come.The range and speed of movement of the parts of machines are elements in designing that admit of a definite determination from the work to be accomplished, but arrangement cannot be so determined, and is the most difficult to find data for. To sum [154] up these propositions we have:
  • 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 am tired, weary, worn-out," the Countess cried. "I am sick of it all, sick of the world, and sick to death of myself. Go to bed."We met only a few Germans on the road from Brussels to Charleroi, and found no garrison except in the townlet Hal. Very little burning had taken place on this road, but so much the more plundering and looting. A woman took us all over her house in the neighbourhood of Brussels, to show us the total wrecking. Small pieces of furniture were generally taken away, but stoves, kitcheners, and cupboards were smashed. She herself had had her face badly wounded, because she had hidden herself in the cellar when the Germans came near, and they had beaten her out of that with their rifle-butts. Many other women were treated in the same manner.

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