TWO:Sire, it would be cheap at a hundred ducats.

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:Who can imagine the conflicting emotions of joy and wretchedness, of triumph and shame, of relief and chagrin, with which the heart of Frederick must have been rent! The army of Prussia had triumphed, under the leadership of his generals, while he, its young and ambitious sovereign, who had unjustly provoked260 war that he might obtain military glory, a fugitive from the field, was scampering like a coward over the plains at midnight, seeking his own safety. Never, perhaps, was there a more signal instance of a retributive providence. Frederick knew full well that the derision of Europe would be excited by caricatures and lampoons of the chivalric fugitive. Nor was he deceived in his anticipations. There was no end to the ridicule which was heaped upon Frederick, galloping, for dear life, from the battle-field in one direction, while his solid columns were advancing to victory in the other. His sarcastic foes were ungenerous and unjust. But when do foes, wielding the weapons of ridicule, ever pretend even to be just and generous?
  • 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:Speaking of Frederick at this time, Bielfeld says: Notwithstanding all the fatigues of war, the king is in perfect health, and more gay and pleasant than ever. All who approach his majesty meet with a most gracious reception. In the midst of his camp, and at the head of sixty thousand Prussians, our monarch appears to me with a new and superior air of greatness.This was a very serious suggestion. None of these sovereigns professed to be influenced by any other considerations than their own interests. And it was manifest that Austria could easily outbid Prussia, if determined to purchase the French alliance. For a moment the king was silent, apparently somewhat perplexed. He then said,

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

THREE:His Prussian majesty rides much about, often at a rapid rate, with a pleasant business aspecthumane, though imperative; handsome to look upon, though with a face perceptibly reddish. His age, now thirty-eight gone; a set appearance, as if already got into his forties; complexion florid; figure muscular, almost tending to be plump.
  • 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:Shall we order that to cease, your majesty?

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