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:Under cover of these festivities important political matters were discussed. The question of the partition of Poland arose, and arrangements were made for another interview. Soon after this, Frederick sent to Catharine a sketch of a plan for partitioning several provinces in PolandRussia, Prussia, and Austria each taking a share. To which Petersburg, intoxicated with its own outlooks on Turkey, paid not the least attention.179 The second interview, of five days, commenced on the 3d of September, 1770, at Neustadt, near Austerlitz, which has since become so famous.
  • 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:At ten oclock at night on the 9th of September, the Russian camp went up in flame. The next morning not a Russian was526 to be seen. The whole army had disappeared over the hills far away to the north. Frederick immediately dispatched eight thousand men under General Platen to attack the flank of the retreating foe, and destroy his baggage-wagons. The feat was brilliantly accomplished. On the 15th of September, before the dawn of the morning, General Platen fell upon the long train, took nearly two thousand prisoners, seven cannon, and destroyed five thousand heavily-laden wagons.You will beforehand inform the high mightinesses in regard to that Advice of April 24th, which they determined on giving me, through his excellency General Ginckel, along with his excellency Lord Hyndford, that such advice can be considered by me only as a blind complaisance to the court of Viennas improper urgencies. That for certain I will not quit Silesia till my claims be satisfied. And the longer I am forced to continue warring for them here, the higher they will rise.

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

THREE:
  • 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:The King of Prussia had an army of two hundred thousand men under perfect discipline. The Old Dessauer was dead, but many veteran generals were in command. It was manifest that war would soon burst forth. In addition to the personal pique of the Duchess of Pompadour, who really ruled France, Louis XV. was greatly exasperated by the secret alliance into which Frederick had entered with England. The brother of the Prussian king, Augustus William, the heir-apparent to the throne, disapproved of this alliance. He said to the French minister, Valori, I would give a finger from my hand had it never been concluded.On quitting me he said, I hope, sir, you will leave me your name. I am very glad to have made your acquaintance. Perhaps we shall see one another again. I replied as was fitting to the compliment, and begged him to excuse me for having contradicted him a little. I then told him my name, and we parted.
