TWO:"True, too," Brewster admitted perforce."What did I do? The same as he done unto me. Let the air into his sombrero." He told them that he was studying the flora of the country, and travelling quite alone, with an Indian pony, a pack-mule, and a dog—a prospector's outfit, in short.

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:In the period of madness, more or less enduring, of the victim of the Great Powers' policy, somebody who is innocent usually suffers. Sometimes the Powers know it, oftener they do not. Either way it does not worry them. They set about doing their best to destroy, and that is their whole duty.
  • 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:Two aimless citizens lounged on their horses, rapt in argument and the heavy labor of chewing—so much so that they barely took notice of the troops."Mr. Ellton was here this morning," Felipa told him, "and he will be in again before retreat."

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

THREE:"I can't see why you should take pleasure in shooting these harmless things," he said impatiently; "the foot-hills are full of quail, and there are ducks along the creek. For that matter you might try your skill on prairie dogs, it seems to me."
  • 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:It was plainly the cave. He went and stood in the mouth and looked into the dark, narrowing throat. A[Pg 219] weird silence poured up with the damp, earthy smell. He went farther in, half sliding down the steep bank of soft, powdery, white earth. There was only the uncanny light which comes from reflection from the ground upward. But by it he could see innumerable tiny footprints, coyote, squirrel, prairie-dog, polecat tracks and the like. It took very little imagination to see yellow teeth and eyes gleaming from black shadows also, although he knew there were no dangerous animals in those parts.

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