TWO:Perhaps the Scripture texts had taught their lesson, or perhaps there yet lingered a hope of learning that which her husband would not tell. Anyway, for the week which the woman lay on the cot in the little whitewashed chamber, which had no outlet save through the sitting room where some one was always on guard night and day, Mrs. Taylor served her with a good enough grace.

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:"On his ranch, living on the fat of a lean land, I believe. He's rich, you know. I don't know much about them. I've small use for them. And I used to like Cairness, too. Thought he was way above his job. Those squaw-men lose all sense of honor."
  • 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 aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:"Don't bring them into it," he implored. "If you will not come away, I will tell you now, Felipa, that I love you." He was more in earnest than Landor had been. She felt that herself. His voice broke, and he paled.
  • 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:Cairness had made a tune for himself and was putting to it the words of the ill-fated poet of his own Land of the Dawning.The sun was now high and blazing down into the one street of the mud settlement. The enlisted men[Pg 116] were angry that Landor, fearing they, too, would be led astray into dives, would not dismount them. Sitting still in the full sun, when even in the shade the mercury is many degrees above the hundreds, is not calculated to improve the disposition. But at length the volunteers were herded together. The thirty-five promised had dwindled to eight, and Foster was not of the number. He came lurching up at the last moment to explain that he would be unable to go. His wife was in hysterics, he said.

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