TWO:There was a pause. Mrs. Masters drew in[Pg 119] her lip and folded her arms stiffly. The Doctor stared hard at her for a moment, and almost betrayed himself. Then he threw back his head and laughed with the air of a man to whom all issues of life, great and small, had become the object of a graduated hilarity. "Then upon some other lady will fall the supreme honour," he observed.JAPANESE STEAM CORVETTE. JAPANESE STEAM CORVETTE.

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:LX TIDINGS"We came to the village of Nan-kow, at the entrance of the Nan-kow Pass, and stopped there for dinner. Our ride had given us a good appetite, and though our cook was not very skilful in preparing our meal, we did not find fault with him, as we did not wish to run the risk of waiting while he cooked the things over again. The Chinese inn at Nan-kow is not so good as the Palace Hotel at San Francisco; in fact, it is as bad as any other hotel that we have seen. They don't have much pleasure travel in this part of the world, and therefore it does not pay them to give much attention to the comfort of their guests.
  • 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 Clockwork man shook his head. "We have houses, but they are not full of things like yours are, and we don't live in them. They are simply places where we go when we take ourselves to pieces or overhaul ourselves. They are" his mouth opened very wide, "the nearest approach to fixed objects that we have, and we regard them as jumping-off places for successive excursions into various dimensions. Streets are of course unnecessary, since the only object of a street is to lead from one place to another, and we do that sort of thing in other ways. Again, our houses are[Pg 146] not placed together in the absurd fashion of yours. They are anywhere and everywhere, and nowhere and nowhen. For instance, I live in the day before yesterday and my friend in the day after to-morrow.""But you look real," objected Arthur.

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

THREE:"How can I tell?" was the reply; "that's none of my business. Probably he took his meals at the nearest restaurant and slept at home.[Pg 70] And if you don't believe my story, I can't help itI've done the best I can.""Whom have you come for, sir?"
  • 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:"And she--ah, yes. I see; and I see, too, that in all she ever said or did or seemed, before, she never made herself such a treasure to be longed for and fought and lived for as in the way in which she--" He paused.I remarked that had I been in her place I should either have sunk into the mire, so to speak, or thrown myself, literally, into the river.

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