TWO:"Indeed, I am not joking," she assured him earnestly. "It is quite true. Ask any one. Only don't let them know it was I who wounded him. They have never so much as suspected it. Fortunately I thought of you and ran home all the way, and was in my tent before it occurred to any one to come for me." She burst into a low laugh at his countenance of wrath and dismay. "Oh! come, Jack dear, it is not so perfectly, unspeakably horrible after all. I was disobedient. But then I am so sorry and promise never, never to do it again."

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:Brewster nodded. He had seen the same thing himself. The territorial citizen was a known quantity to both of them.
  • 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:

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

THREE:As they walked back to the post, Landor did not speak to Felipa. There was nothing he could say unless he were to storm unavailingly, and that was by no means his way. And there was nothing for which he could, with reason, blame her. All things considered, she had acted very well. She moved beside him serenely, not in the least cowed.But she only considered the insects, which were beginning to move again, and answered absently that she knew it, that he had said it before. "Oh! Mr. Brewster, bet quickly," she urged.
  • 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:Visiting the guard is dull work, and precisely the same round, night after night, with hardly ever a variation. But to-night there occurred a slight one.[Pg 187] Landor was carrying his sabre in his arm, as he went by the back of the quarters, in order that its jingle might not disturb any sleepers. For the same reason he walked lightly, although, indeed, he was usually soft-footed, and came unheard back of Brewster's yard. Brewster himself was standing in the shadow of the fence, talking to some man. Landor could see that it was a big fellow, and the first thing that flashed into his mind, without any especial reason, was that it was the rancher who had been in trouble down at the sutler's store.

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