TWO:Another time, hearing that the Princess wanted some shoes for a ball, he sent an express which travelled night and day to Paris to get them.In a very short time, however, she was summoned out of the prison and conducted by the gaolers into the presence of Tallien.

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:I knew it, replied Fronsac, and passed on.These things are impossible. I shall never believe they meditate such atrocities.
  • 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:The errors of her youth she abandoned and regretted, and her latter years had by no means the dark and gloomy character that she had pictured to herself, when she left the Palais Royal and fled from France and the Revolution, in whose opening acts she had rejoiced with Philippe-galit.
  • 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:What the devil of a story are you telling me, Chevalier de ? cried his tormentor. Where did you have supper last night? I believe you have drunk too much.
