TWO:"But aren't you real?" Arthur could not refrain from asking.

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:No, but we must try to be friends now.
  • 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:"No, he's Federal, Confederate or guerilla as it may suit his bloody ends."Hetty's uncle was evidently flattered. He liked talking of his own work, for his heart was in it, and he had for audience one of the most brilliant and beautiful women in London. His voice was something high pitched and it carried easily to Hetty's ears. Apparently, Bruce was gone, for the girl could see nothing of him anywhere. She was only too glad for a chance to sit down quietly and ponder over the disturbing events of the evening. Nobody was likely to be particularly interested in Leona Lalage's governess.

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

THREE:This did not quite seem to break the ice, and Mrs Goodford looked in some contempt at her daughter with her eyes, little and red and wicked like an elephants. Her face was so deeply wrinkled that her features were almost invisible in the network, but what there was of them was exceedingly sharp. She had taken off her bonnet, a sign that she meant to stop all afternoon, and showed a head very sparsely covered with white hair: at the back of it was fixed on a small bun of bright auburn, which no doubt had been the colour of her{20} hair some forty years ago. This bun always fascinated John: it was impossible to conjecture how it was attached to his grandmothers head.LIX UNDER CHARLOTTE'S WINDOW
  • 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:She had his letters opened for him with her usual speed, but as she worked he could see by the soft creased line between her eyebrows, even as he{158} had seen it yesterday morning, when she was anxious about her brother, that something troubled her. To-day, however, he did not question her: she might tell him if she felt disposed, and guessing that it was connected with the events of last night, his instinct told him that it was for her to speak or be silent. Then, when she had opened the letters, she placed them by him, and without a word, took up her writing-block and pencil for the shorthand dictation. But still her brow did not clear, the smudge of shadow lay perpendicularly between her eye-brows, as fixed as if it was some soft pencil mark on the skin.Gregg smiled. "After all," he remarked, allowing a suitable pause to follow the Doctor's impassioned words, "it will not be for you or[Pg 187] me to decide the matter. Our humble part will be to produce the object of the problem. Wiser men than ourselves will have to interpret its significance."

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