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:Chapter 7Once when Felipa got out of the ambulance to tramp beside it, in the stinging snow whirls, and to start the thin blood in her veins, she had looked up into his blanket-swathed face, and laughed. "I wonder if you looked like that when you took me through this part of the world twenty years ago," she said.
  • 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:There was one who had done so now. The troops looking up at him, rejoiced. He was crucified upon an[Pg 135] improvised cross of unbarked pine branches, high up at the top of a sheer peak of rock. He stood out black and strange against the whitish blue of the sky. His head was dropped upon his fleshless breast, and there was a vulture perched upon it, prying its hooked bill around in the eye sockets. Two more, gorged and heavy, balanced half asleep upon points of stone.

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

THREE:"I heard you," said the little man; "what's the other?"—"Oh, I dare say I'll fail on that," he answered indifferently, and taking up his sombrero went out to saddle his horse.Chapter 8
  • 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:Landor said that he had put in a requisition for kippered mackerel and anchovy paste, and that the commissary was running down so that one got nothing fit to eat. He was in an unpleasant frame of mind, and his first lieutenant, who messed with him, pulled apart a broiled quail that lay, brown and juicy, on its couch of toast and cress, and asked wherein lay the use of taking thought of what you should eat. "Every prospect is vile, and man is worse, and the sooner heaven sends release the better. What is there in a life like this? Six weeks from the nearest approach to civilization, malaria in the air by night and fire by day. Even Mrs. Landor is showing it."The lean hands found the knots, untied them, and threw back the flaps defiantly. The ten pairs of eyes were fastened on her again. She returned the gaze steadily, backing to a little camp table and slipping her hand under a newspaper that lay upon it. "Ukishee, pronto," she commanded, in the accepted argot. They stood quite still and unyielding; and she knew that if she were to be obeyed at all, it must be now. Or if she were to die, it must be now also. But the hand that drew from beneath the newspaper the little black-butted Smith and Wesson, which was never out of her reach, did not so much as tremble as she aimed it straight between the eyes of the foremost buck. "Ukishee," she said once again, not loudly, but without the shadow of hesitation or wavering. There answered a low muttering, evil and rising, and the buck started forward. Her finger pressed against the trigger, but before the hammer had snapped down, she threw up the barrel and fired into the air, for a big, sinewy arm, seamed with new scars, had reached out suddenly and struck the buck aside. It was all done in an instant, so quickly that Felipa hardly knew she had changed her aim, and that it was Alchesay who had come forward only just in time.
