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 have no one with me, replied she, but my daughter and her governess.And it was well-known that he had ordered the assault upon the fortress of Otshakoff to be prematurely made because she wished to see it.
  • 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:But her greatest love was for her father; it was almost adoration. Louis Vige was exactly opposite in disposition to his wife, to whom he was, however, devoted. Kindly, affectionate, light-hearted, and thoughtless, his love for her did not interfere with his admiration for other women; a pretty grisette was quite able to turn his head, and on New Years day he would amuse himself by walking about Paris, saluting the prettiest young girls he met, on pretence of wishing them a happy new year.

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

THREE:The Duc de Noailles, her father, finding he could not recover his h?tel, returned philosophically to Switzerland, and bought a house on the Lake of Geneva. He had married the Countess Golowskin, which at first was a grief to his daughters, but after a time they were reconciled to the idea, and got on very well together.
  • 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:Her great uncle, the old Marchal de Mouchy, had never left the King on the terrible day of the 20th of June, but had stood by him making a rampart of his own body to protect him from the hordes of ruffians who were invading the palace; her father, on hearing of these events, had left his refuge in [230] Switzerland and hurried back to the King; so did her cousin, the Prince de Poix. Both of them had sympathised with the earlier Liberal ideas at first; but now, horrified at the fearful development of their principles, they bitterly regretted their folly and came to place their lives at the service of their King.The Chevalier tried in vain to escape. The apparent madman seized him by the arm.
