TWO:People were presented first to the King, then to the Queen, in different salons; of course magnificently dressed. The King, now that he was Louis XVI., very often did not speak but always made a friendly, gracious gesture, and kissed the lady presented, on one cheek only if she was a simple femme de qualit; on both if she was a duchess or grande dEspagne, or bore the name of one of the families who possessed the hereditary right to the honours of the Louvre and the title of cousin of the King.

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:Accordingly he pretended to be mad, and wandered all day about the streets of Paris, wearing an old Court dress and an enormous wig, talking extravagantly, making foolish jokes, but all the time looking for the Chevalier .
  • 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:Les bonnes m?urs et labondance.

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

THREE:As time went on Trzia found that her influence as well as that of Tallien was rapidly declining. Her salon was not at all likely to last long. Those of the court and of society before the Revolution had been of an entirely different order; held by women who, besides their beauty or other attractions, were in an assured position, surrounded by well-known connections and friends, forming an intimate society sure to be met at their houses, and always ready to carry on conversation, avoid all topics likely to give offence, and make themselves generally agreeable. Nobody was admitted there who [341] was not accustomed to the usages of the world or who would interfere with the harmony and general tone of the house. People went there, not to engage in political discussions or to make love to their hostess, but to spend a pleasant evening and meet the friends they knew and liked. These salons continued to be frequented by their usual guests year after year without any more change than the lapse of time inevitably brings.
  • 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.
