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:Most of the great painters were to be found at the house in the rue du Gros-Chenet, where the suppers were as gay and pleasant as of old.Mme. Auguier sent her husbands valet de chambre [81] to help him up, and take him into the kitchen. Presently the valet returned, saying, Madame is indeed too kind; that man is a wretch. Here are some papers which have fallen out of his pocket. He gave them several sheets of papers, one of which began, Down with the Royal Family! down with the nobles! down with the priests! and all of which were filled with a tissue of blasphemies, litanies of the Revolution, threats and predictions horrible enough to make their hair stand on end.

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

  • 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:Mlle. de Mirepoix thought at first that he was [197] joking, but finding the transaction was serious, fainted with joy. They were married and belonged to the Queens intimate circle, but the union did not turn out any more happily than might have been expected. Soon the Revolution swept all away; they emigrated, but not together; he went to Germany, she to England. When afterwards he came to London, his wife went to Italy.See this absurd Valence, on his knees to me, asking for the hand of my niece.
