TWO:The man laughed.

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:In the streets people recognised their own carriages turned into hackney coaches; the shops were full of their things; books with their arms, china, furniture, portraits of their relations, who had perhaps perished on the scaffold. Walking along the boulevard one day soon after her return to Paris she stopped at a shop, and on leaving her address, the lad who was serving her exclaimedIT will not be possible in a biography so short as this, to give a detailed account of the wandering, adventurous life led by Mme. de Genlis after the severance of her connection with the Orlans family.
  • 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:
  • 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:Fragonard, the Proven?al, had more depth and dramatic feeling, the passion of the south and the love of nature in his work gave a stronger, truer, more impressive tone to his pictures; but Boucher, the favourite painter of Louis XV., the Marquise de Pompadour, and the court would seem from his pictures to have looked upon everything in life as if it were a scene in a carnival or fte. His goddesses and saints, even the holy Virgin herself, were painted from models from the theatre, and looked as if they were; his gardens, roses, silks, satins, nymphs, fountains, and garlands were the supreme fashion; every one wanted him to paint their portrait; he had more commissions than he could execute, and his head was turned by the flattery lavished upon him.Just then Lacomb, president of the tribunal, who had been told that the aristocrats who went with the English captain were saved by her, came up and ordered her arrest.
