TWO:Despite his fifty years, and the hard dry business atmosphere of his life, there was something amazingly boyish in the inward agitation{156} in which Keeling, arriving ten minutes before his time at his office next morning, awaited Norahs coming. His midnight excursion, dictated by some imperative necessity from within had, even if it was not a new stage in his emotional history, revealed a chapter already written but not yet read by him. He expected too, quite irrationally, that some corresponding illumination must have come to the girl, that she, like himself, must have progressed along a similar stage. He pictured himself telling her how he had left his house in order to have the satisfaction of seeing her lit window; he had a humorous word to say about the state of his dress shoes (in place of which he must not forget to order a pair from the boot and shoe department this morning). He could see her smile with eyes and mouth in answer to his youthful confession, as she always smiled when, as often happened now, some small mutual understanding flitted to and fro between them, and could easily imagine the tone of her reply, Oh, but how dreadfully foolish of you, Mr Keeling. You want to be laid up too, like Charles. She would not say more than that, but there would be that glimmer of comprehension, of acceptance, that showed she had some share in the adventure, that she allowed it, looked on it with the kind eye of a friend.Arthur finished his tea and got up from his chair. Conscious that his efforts so far had not carried conviction, he spent a few moments of valuable time in an attempt to supplement them.

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:Your father doesnt like working hours interfered with, my dear, said Mrs Keeling. But well do what we can. Anyhow, Mr Silverdale will have to change before he goes to church.
  • 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:"I have one or two things," he said, after a few words of greeting, "that I'd like to send home--to my mother--and my wife; some trifles--and a message or two; if I--if--if I--""The streets of Chin-kiang are narrow and dirty, and the most of them that we saw seemed to be paved with kitchen rubbish and other unsavory substances. The smells that rose to our nostrils were too numerous and too disagreeable to mention; Fred says he discovered fifty-four distinct and different ones, but I think there were not more than forty-seven or forty-eight. The Doctor says we have not fairly tested the city, as there are several wards to hear from in addition to the ones we visited in our ramble. I was not altogether unprepared for these unpleasant[Pg 331] features of Chin-kiang, as I had already taken a walk in the Chinese part of Shanghai.
  • 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:"Japan abounds in sulphur, and the supply is said to be inexhaustible. The copper used at the mint for making the Japanese small coins is of native production, and so is most of the silver; but occasionally the supply of the latter metal runs short, and then American silver comes into play. Last year nearly half a million trade-dollars were melted at the mint at Osaka, to be made into Japanese yens, and this year a large number have met a similar fate. The American trade-dollar has not yet become a popular coin for circulation in Japan and China, but is in good demand for the melting-pot. But I suppose we do not care what they do with our silver money so long as they pay for it; and the more they melt up, the better we shall be pleased."
