TWO:Philippe-galit had wearied Robespierre with his petitions to be released, and that worthy remarked to Fouquier-Tinville

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:Then Trzia knew that she was safe, and that Tallien, for her sake, had overthrown the monster and broken the neck of the Terror. Soon he appeared in triumph to throw open the gates of La Force, and the following day Trzia, accompanied by Frron and Melun de Thionville, went herself to the club of the Jacobins and closed it without any one venturing to take the keys from her.
  • 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:[129]Every one betrays the Republic. The citoyen Tallien is granting pardon to aristocrats.

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 Chartres now also looked with disapproval upon his fathers conduct. In his Mmoires Louis XVIII. quotes a letter of M. de Boissy, who says that the only republican amongst the sons of galit was the Duc de Montpensier. [128]
  • 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:Mme. de Montagu started first with her husband, leaving her boy with her aunt and her girl with a friend. As they were still on the proscribed list they travelled under the names of M. et Mme. Mongros. They took up their quarters in Paris at a small house kept by an old servant of M. de Thsan, where they found their cousin, the Duchesse de Duras and the Doudeauville, living under their own names, in little rooms very clean, but so scantily furnished that if any visitors arrived they had to borrow chairs from each other.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.
