TWO:Johns eye, which had exactly as much expression in it as a dead codfishs, cowed him for a moment, but he quickly recovered.

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:
  • 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: "Now, mother, this letter is addressed to you, but it is intended for everybody; and I know you'll read it to everybody, and have it handed round, so that all can know where I am and what I have told you about Japan. When I don't write to each one of you, I know you will understand why it is,because I am so busy, and trying to learn all I can. Give my love to each and every one in the family, and tell Mary she knows somebody outside of it that wants a share. Tell her I often think of the morning we left, and how a handkerchief waved from the railway station when we came away. And tell Mary, too, that I haven't yet opened her list of things I am to get for her; but I haven't forgotten it, and have it all safe and right. There are lots of pretty things to buy here; and if she has made a full catalogue of Japanese curiosities, she has given me enough to do for the presentand the presents.SNOW-SHEDS ON THE PACIFIC RAILWAY.

  • 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:Two gasping words from Charlotte brought his ear down, and with a worshipping light in his eyes he said to her "Yes,--yes!" and then to me, "Yes, I shall report to him in person. Now, Smith, the top of your speed!"
