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.

  • 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:I have always been persuaded, she says in one of her letters, that if the victims of that time of execrable memory had not had the noble pride to die with courage, the Terror would have ceased much sooner. Those whose intelligence is not developed have too little imagination to be touched by silent suffering, and it is much easier to arouse the compassion than the imagination of the populace.Her first care had been to release from the Carmes her fellow-prisoners, Josphine de Beauharnais and Mme. dAiguillon, who now formed an intimate part of her society and that of Barras. To them also came Mme. de Stael, wife of the Swedish Ambassador, the beautiful Mme. Regnault-de-Saint-Jean-dAngely, Mme. Cambys, and many others thankful to escape from the shadows of prison and death to the light of liberty and pleasure. The restraints of religion and morality were, of course, non-existent; liaisons and [338] licence were the order of the day, and Trzia was not likely to be an exception to the general custom. She had, besides her daughter by Tallien, other children, who, as no other name belonged to them, were called Cabarrus. And her being or calling herself Talliens wife was no reason why she should renounce her natural right to love any one else where, when, and as often as she pleased.

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

THREE:I am enchanted to see you again, my dear Chevalier de , and I hope you are in a better humour to-day. Instead of the dinner you refused, accept the djeuner I offer you this morning.The Duke put her back in the carriage and sat holding her in his arms; of what passed during their drive she never had a clear recollection, except that in a voice almost inaudible she ventured to ask if Rosalie was still alive, to which her father replied upon his word of honour that he had heard nothing of her. More, she dared not say, frightful visions rose before her eyes, she fancied herself seated upon the tumbril bound with other victims, and the thought was almost a relief to her.
  • 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.
