TWO:"Never mind, we must have a long talk. At present there is a verbal message for me; what is it?"

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:That last fact occupied a central place in his mind just at present, but it was also another source of irritation. Lilian was intellectual as well as fascinating, and the former attribute became more marked as they grew more intimate. Instead of charming little notes inviting him to tea he now received long, and, he was obliged to admit, quite excellent essays upon the true place of woman in modern life. He was bound to applaud, but such activity of mind was by no means to his taste. He liked[Pg 47] a woman to have thoughts; but a thinking woman was a nuisance.As regards size, he said, perhaps you will come up and have a look at my books again, and get a guide from them.
  • 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:I galloped away filled with an absurd foreboding that he was too sure, which may have come wholly from my bad temper at being started too late to see our ladies before morning. However, at two that night, my saddle laid under my head, and haversack under the saddle, I fell asleep with all Gallatin for my bedchamber, the courthouse square for my bed, the sky for my tester, the pole-star for my taper, hogs for mosquitoes and a club for a fan.

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

THREE:"True; but neither are the enemy, and they're early risers, you know."The Doctor explained that the hole was a cask set in the ground, and that it probably contained liquid manure. The Japanese use it for enriching their fields. They keep it in these holes, covered with a slight roof to prevent its evaporation as much as possible, and they spread it around where wanted by means of buckets. The great drawback to a walk in a Japanese field is the frequency of the manure deposits, as the odor arising from them is anything but agreeable. Particularly is this so in the early part of the season, when the young plants require a great deal of attention and nourishment. A nose at such times is an organ of great inconvenience.
  • 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 have sent some picked men to catch him if they can," said Ferry, and the racked sufferer lifted a hand in approval. Camille came to her aunt and whispered "Mr. Gholson with two doctors." The wounded captive heard her.

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