TWO:The horse came down to a walk. She had lost all control of the reins now, and clung to the pommel with both hands, swaying from side to side. She could hear galloping hoofs, behind and in front—or was it only the blood, the icy cold blood, pounding in her ears?

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: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.Cabot told him that he was preparing to remain where he was. His voice was firm and his lips were[Pg 4] set under the sun-bleached yellow of his beard, but his face was gray, for all the tan. He lapsed into the speech of other days. "No use, Jack," he said; "it's worse than court-martial—what I've got to face here. Just leave me some water and rations, and you go on."
  • 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:[Pg 77]"I am going back to my ranch on the reservation," he said measuredly.

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

THREE:"De veras?" asked Cairness, sharply. He was of no mind to lose her like this, when he was so near his end."I see dem pass by my ranch. Dey weel run off all my stock, seexty of dem, a hundred mebee. I come queek to tell you."
  • 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 don't," Cairness differed; "it's unreasonable. There is too much sympathy expended on races that are undergoing the process of extinction. They have outgrown their usefulness, if they ever had any. It might do to keep a few in a park in the interests of science, and of that class of people which enjoys seeing animals in cages. But as for making citizens of the Indians, raising them to our level—it can't be done. Even when they mix races, the red strain corrupts the white."Ellton stood by the door, with his hands in his pockets, and a countenance that tried hard to maintain the severity of discipline. But he was plainly enjoying it.

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