TWO:"He was lured to disaster and death by a man whose supreme purpose was, and is to-day, revenge upon me. That man drew him to his ruin purely in search of my life." Charlotte sat with her strange in-looking, out-looking gaze holding the gaze of her questioner until for relief he spoke.

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:"At the last place where we stopped before reaching the Great Wall we found the people very insolent, both to us and to the men in our employ. They said rude things to us, and perhaps it was fortunate that we did not understand Chinese, or we might have been disposed to resent their impudence, and so found ourselves in worse trouble. Our guide said something to a lama, or priest, and he managed to make the people quiet, partly by persuasion and partly by threats. Some of the men had been drinking too freely of sam-shoo, which has the same effect on them as whiskey has on people in America. It is not unusual for strangers in this part of China to be pelted with stones; but the natives are afraid to do much more than this, as they would thereby get into trouble.
  • 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:"Let me explain," urged the Clockwork man, who was gaining in verbal ease and intellectual elasticity every moment. "Supposing[Pg 90] I was to hit you hard. You would fall down. You would become supine. You would assume a horizontal position at right angles to your present perpendicularity." He gazed upwards at the tall figure of the constable. "But if you were to hit me, I should have an alternative. I could, for example, fall into the middle of next week."

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

THREE:
  • 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 then there came for him the direct glance, a little dim yet, with the clear shining after rain beaming through it.

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