TWO:They decided to stay at Aix for the present, and had just taken and furnished a small apartment when they heard the French army, under Dumouriez, was advancing upon Aix.Yes. What do you want of me?

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:[231]
  • 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:However, Mme. Le Brun was overjoyed to see Jeanne, and to keep her in Paris, although she refused to live with her, because the people with whom she persisted in associating were so objectionable that her mother would not meet them.

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

THREE:The daughter of the Vicomtesse de Noailles was married to the Marquis de Vrac. Of the sons, Alexis, between whom and Pauline there was an [264] especially deep affection, and whose principles entirely agreed, refused to accept any employment under the government of Buonaparte. In consequence of the part he took in favour of the Pope he was imprisoned, and only released by the influence of his brother Alfred, an ardent soldier in the Imperial army, who, after distinguishing himself and winning the favour of the Emperor, was killed in the Russian campaign.This foretaste of the Revolution Mme. de Genlis did not like at all, and she began to think she would rather not be in France now that the plans and friends so lately her admiration were succeeding so well.
  • 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:Louis XV., at this time about forty-five, extremely handsome, immersed in a life of pleasure, magnificence, and vice, was then under the domination of the Duchesse de Chateauroux, ma?tresse en titre, the youngest of the five daughters of the Marquis de Nesle, four of whom had been for a longer or shorter period the mistresses of Louis XV. That such a father as the King should have had such a son as the Dauphin is astonishing indeed. The author of some fascinating memoirs of the day writes of him, If I have not yet spoken of M. le Dauphin, do not suppose that it is from negligence or distraction, it is because the thought of his death always envelopes my mind like a funeral pall. His premature end is ever present with me, and is a subject of regret and affliction which I cannot approach without terrible emotion. He was so grievously mourned for, he has been so universally and justly praised, that there would not be much left me to tell you if I were not to speak of his perfect beauty, which was the least of his perfections, and which perhaps for that very reason, the writers of his time never mention.... His face and figure were perfectly formed; and he had, especially in the movement of his lips and the gentle, melancholy pride of his great black eyes, an expression which I have never seen unless perhaps in some old picture of the Spanish school ... he might have been an archangel of Murillo.... He carried with him the happiness of France and the peace of the world, but one felt that it would have [166] been perfect happiness, and that one would never experience it. The subjects, perhaps the family of the King his father had provoked such terrible chastisements, that we may sorrowfully say that France and the French of the eighteenth century were not worthy to be ruled by the Dauphin Louis.
