TWO:He fingered nervously with his watch, and then his eye rested for a second upon the other's head gear.

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:Captain Spofford was a weather-beaten veteran who gave little attention to fine clothes, and greatly preferred his rough jacket and[Pg 59] soft hat to what he called "Sunday gear." He was much attached to his telescope, which he had carried nearly a quarter of a century, and on the present occasion he brought it into the cabin, and held it in his hand while he narrated his whaling experiences. He explained that he could talk better in the company of his old spy-glass, as it would remind him of things he might forget without its aid, and also check him if he went beyond the truth.
  • 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:Her response was a question, which he repeated: "Is he hurt? no, Richard never gets hurt. Shall he tell us whatever he knows?"

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

THREE:"I suppose that's so," laughed the officer. "I'll tell you how it was. My guard were just about to hang me for saying I thought we had a right to make soldiers of the darkies, when your friend came galloping along, saw the thing, and rushed in and cut the halter with his sword. And when they demanded to know who and what he was, he told them Durand, and that they'd hear it again, for he should report them."
  • 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:Well, Im sure its been a very pleasant if a very quiet evening, she said. Theres nothing nicer than to dine, as you may say, tte--tte like that and have a little agreeable conversation afterwards, not but what I should have been sorry to have as tough a pheasant as that served at my table, for I declare I could hardly get my teeth into it though it did come on a silver plate, and nothing but a nut and an apple for dessert, though you can get choice grapes so cheap now. But there! what does that matter when you dine with{172} friends? Such a pleasant talk as I had too with Lady Inverbroom, who, Im sure, is a very sensible and agreeable sort of woman. Nothing very gifted, I dare say, but a great deal of common sense. Common sense now! I often wish it was commoner. But the time passed so quickly while you and Lord Inverbroom were talking together in the dining-room that I was quite surprised when you came in. The soup, too, did you not find it insipid? But I expect Lady Inverbroom does not have the sort of cook that I have always been accustomed to. No jewels either, just that little diamond brooch, which made me feel that I was too fine with the beautiful pearl pendant you gave me for my birthday. Dont you agree with me, Thomas?
