TWO:...Perhaps this was the last time that Keeling would ever listen to those maunderings. That would be determined in the bluebell wood. Perhaps to-morrow evening....

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 many years ago, China and Japan were regarded as among the barbarous nations. The rest of the world knew comparatively little about their peoples, and, on the other hand, the inhabitants of those countries had only a slight knowledge of Europe and America. To-day the situation is greatly changed; China and Japan are holding intimate relations with us and with Europe, and there is every prospect that the acquaintance between the East and the West will increase as the years roll on. There is a general desire for information concerning the people of the Far East, and it is especially strong among the youths of America."You think so? But I have done. I will keep it no longer! Ah, I never kept it; 'twas she! Without taking it from me she kept it--'with all diligence'; otherwise I should have lost it--and her, too--and all that is finest and hardest to keep--long ago. Give me that paper; come; saddle up; you may go with me if you want, as my courier." No bugle had sounded, yet the whole camp was softly and diligently astir. We rode toward the staff tents; the pulse of enterprise enlivened him once more, though he clung to the same theme. "I have her heart now, Smith, and I will keep that with all diligence, for out of that are the issues of my life--if I live. And if I do live I will have her if I have to steal her even from herself, as last night from the Yankees."
  • 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:"Yes," I replied, "in that direction."Then he began dictating to her something about linoleums. But Ive not done with him yet. The dear man! Ill plague his life out for him if youll only help me.

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

THREE:"Quite so," answered Dr. Bronson; "I don't think Frank is likely to be forgetful of home."
  • 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:Keeling was completely puzzled: if he had ventured to speak in this sense of Lady Keeling, he knew he would have made a sad mess of it. In his mouth, the same material would have merely expressed itself in a rude light. He tried rather mistakenly to copy the manner that was no manner at all.

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