TWO:Soon the whistle sounded, the great train rolled into the station, the conductor shouted "All aboard!" our friends took their seats, the bell rang, and the locomotive coughed asthmatically as it moved on.You may do as I bid you without more words, said his father.

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:"Bring up anything you can find," the Doctor whispered in Mrs. Masters' ear, "my friend has had rather a long journey. Anything you can find. Surely we have things in tins.""It is precisely because the Clockwork man can be explained," interrupted Gregg, with some eagerness, "that I find it easy to believe him."
  • 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:HONG-KONG. HONG-KONG.

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

THREE:"And you consider that a reasonable request?"
  • 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:ESTABLISHED OVER 2,000 YEARS."Understand," I said as I wheeled, "I fully expect her to recover."
