TWO:"I don't know," objected Landor; "you get the satisfaction of beginning the row pretty generally—as you did this time—and of saying what you think about us in unmistakable language after we have tried to put things straight for you."

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:Cairness reflected upon this as he fired for exactly the seventh time at a pair of beady eyes that flashed at him over a bush-topped rock by the creek, not five and twenty yards away, and then vanished utterly. There was something uncanny about it, and he was losing patience as well as ammunition. Three bullets from a repeating rifle had about finished him. One had gone through his hat. The eyes popped up again. Cairness fired again and missed. Then he did a thoroughly silly thing. He jumped out from behind his shelter and ran and leapt, straight down, and over to the rock by the stream. The beady eyes saw him coming and sparkled, with an evil sort of laughter.It occurred to Cairness then that with no breath in your lungs and with twelve stone on your chest, speech is difficult. He slid off and knelt beside the rancher, still with the revolver levelled. "Now, why did you do it, eh?" He enforced the "eh" with a shake.
  • 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:At noon Landor got his orders. He was to leave at four o'clock, and when he told Felipa she planned for dinner at three, with her usual manner of making all things as pleasant as possible, and indulging in no vain and profitless regrets. "We may as well have Mr. Brewster and Nellie McLane, too," she decided, and went off in search of them, bareheaded and dancing with excitement. She dearly loved rumors of war. The prospect of a scout was always inspiriting to her.

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

THREE:And the Indian may be trusted to know of these. Here where the jacales clustered, there was grass and wood and water that might last indefinitely. The fortifications of Nature had been added to those of Nature's man. It was a stronghold."Doesn't he, though? Then why doesn't he come around and see me when I'm lying here sick?" He was wrathful and working himself back into a fever very fast.
  • 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:Others of the troops were ordered in, and among them was Landor's. It had gone out for a twenty days' scout, and had been in the field two months. It was ragged and all but barefoot, and its pack-train was in a pitiable way. Weeks of storm in the Mogollons and days of quivering heat on the plains had brought its clothing and blankets to the last stages.

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