TWO:The winter was long, cold, and dreary. Fierce storms swept the fields, piling up the snow in enormous drifts. But for this cruel war, the Prussian, Russian, and Austrian peasants, who had been dragged into the armies to slaughter each other, might have been in their humble but pleasant homes, by the bright fireside, in the enjoyment of all comforts.

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:THE ARSENAL.
  • 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:397 Some years before this time Frederick had taken possession of East Friesland, and had made Emden a port of entry. It was a very important acquisition, as it opened to Prussia a convenient avenue for maritime commerce. With great vigor and sagacity Frederick was encouraging this commerce, thus strengthening his kingdom and enriching his subjects. England, mistress of the seas, and then, as usual, at war with France, was covering all the adjacent waters with her war-ships and privateers. Frederick had inquired of the English court, through his embassador at London, whether hemp, flax, or timber were deemed contraband. No, was the official response. Freighted with such merchandise, the Prussian ships freely sailed in all directions. But soon an English privateer seized several of them, upon the assumption that the planks with which they were loaded were contraband.

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

THREE: Frederick.
  • 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:Though General Soltikof had lost an equal number of men, he was still at the head of nearly eighty thousand troops flushed with victory. He could summon to his standard any desirable re-enforcements. An unobstructed march of but sixty miles would lead his army into the streets of Berlin. The affairs of Frederick were indeed desperate. There was not a gleam of hope to cheer him. In preparation for his retirement from the army, from the throne, and from life, he that evening drew up the following paper, placing the fragments of the army which he was about to abandon in the hands of General Finck. By the death of the king, the orphan and infant child of his brother Augustus William (who had died but a few months before) would succeed to the throne. Frederick appointed his brother Henry generalissimo of the Prussian army.
