TWO:She showed no especial repugnance at the idea, but refused flatly, nevertheless. "I can't do that," she said, dropping down into the hammock and swinging herself with the tip of her foot on the floor.

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:He helped her out. "I have drifted in a way," he went on to explain. "I left home when I was a mere boy, and the spirit of savagery and unrest laid hold of me. I can't break away. And I'm not even sure that I want to. You, I dare say, can't understand." Yet he felt so sure, for some reason, that she could that he[Pg 71] merely nodded his head when she said briefly, "I can." "Then, too," he went on, "there is something in the Indian character that strikes a responsive chord in me. I come of lawless stock myself. I was born in Sidney." Then he stopped short. What business was it of hers where he had been born? He had never seen fit to speak of it before. Nevertheless he intended that she should understand now. So he made it quite plain. "Sidney was a convict settlement, you know," he said deliberately, "and marriages were promiscuous. My grandfather was an officer who was best away from England. My grandmother poisoned her first husband. That is on my mother's side. On my father's side it was about as mixed." He leaned back, crossing his booted legs and running his fingers into his cartridge belt. His manner asked with a certain defiance, what she was going to do about it, or to think.Then he stopped, with every muscle drawn, for he had seen in her answering, unflinching gaze that he was losing her, surely, irrevocably losing her. He let her go, almost throwing her away, and she caught hold of a ledge of rock to steady herself. He picked up the heavy quirt and held it out to her, with a shaking hand, shame-faced, and defiant, too.
  • 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:He turned about and stood still, with his head uncovered, looking straight into her face. Another man might have wished it a little less open and earnest, a little more downcast and modest, but he liked it so. Yet he waited, erect and immovable, and she saw that he meant that every advance should come from her. He was determined to force her to remember that he was a chief of scouts.She stood alone, with the sticky, wet knife in her hand, catching her breath, coming out of the madness. Then she stooped, and pushing the branches aside felt about for her pistol. It lay at the root of a tree, and[Pg 80] when she had picked it up and put it back in the holster, there occurred to her for the first time the thought that the shot in the dead stillness must have roused the camp. And now she was sincerely frightened. If she were found here, it would be more than disagreeable for Landor. They must not find her. She started at a swift, long-limbed run, making a wide detour, to avoid the sentries, bending low, and flying silently among the bushes and across the shadowy sands.

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

THREE:"Well?" said the officer.He went upon the sick report at once, and for three days thereafter raved of crucified women with fair hair, of children lying dead in the ca?on, of the holes in his boot soles, and a missing aparejo, also of certain cursed citizens, and the bad quality of the canned butter.
  • 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:Forbes and her husband having gone away, Felipa lay in the hammock upon the porch and looked up into the vines. She thought hard, and remembered many things as she swayed to and fro. She remembered that one return to Nature long ago of which Landor had not known.

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