TWO:The secret was now out. The tidings flew in all directions that the King of Prussia was in Strasbourg incognito. The king, not yet aware of the detection, called upon the marshal. A crowd of officers gathered eagerly around. The marshal was much embarrassed in his desire to respect the incognito, and also to manifest the consideration due to a sovereign. No one yet ventured to address him as king, though there were many indications that his rank was beginning to be known. Frederick therefore decided to get out of the city as soon as possible. To conceal his design, he made arrangements to attend the theatre with the marshal in the evening. The marshal went to the theatre with all his officers. The building was crowded with the multitude hoping to see the king. Bonfires began to blaze in the streets, and shouts were heard of Long live the King of Prussia. Frederick hastily collected his companions, paid his enormous bill at the Raven, shot off like lightning, and was seen in Strasbourg no more.

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:Sire, here is Monsieur De Voltaire, who is come to receive the orders of your majesty.On the 15th, after a restless night, he did not wake until eleven oclock in the morning. For a short time he seemed confused. He then summoned his generals and secretaries, and gave his orders with all his wonted precision. He then called in his three clerks and dictated to them upon various subjects. His directions to an embassador, who was about leaving, filled four quarto pages.
  • 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:General Czernichef, though at the risk of his head from the displeasure of Catharine, generously consented so far to disobey the orders of his empress. The next day, July 2, 1762, Frederick, with his remaining troops, attacked the foe, under General Daun, at Burkersdorf. From four oclock in the morning until five in the afternoon the antagonistic hosts hurled themselves against each other. Frederick was the victor. On fall of night, Daun, every body having had his orders, and been making his preparations for six hours past, ebbed totally away, in perfect order, bag and baggage; well away to southward, and left Frederick quit of him.172

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

THREE:A spy was sent to Saxony, who reported that there were but twenty thousand troops there. All necessary information was promptly and secretly obtained in reference to roads and fortresses. It required three weeks to receive an answer from Vienna.404 The reply was evasive, as Frederick knew that it would be. In the mean time, his Prussian majesty, with characteristic energy, had mustered on the frontier an army numbering in the aggregate nearly one hundred and fifty thousand men. These troops, in three divisions, with two thousand pieces of artillery, were to make a rush upon Saxony. Among the directions given by Frederick to the leaders of these divisions were the following:
  • 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:

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
