TWO:After the retreat of the Austrians, Frederick returned to his camp to find it plundered and burned. The semi-barbarian assailants had also consigned to the flames eight or ten sick Prussians whom they found there, and several women whom they caught. We found the limbs of these poor men and women lying about, writes General Lehwald.

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:
  • 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:A transient smile flitted across the kings countenance. Then, looking cold again, he added, Follow your own will in that.The merciless satires of Voltaire, exposing Maupertuis to the ridicule of all Europe, proved death-blows to the sensitive philosopher. He was thrown into a state of great dejection, which induced disease, of which he died in 1759. Maupertuis needed this discipline. In the proud days of prosperity he had rejected Christianity. In these hours of adversity, oppressed by humiliation396 and pain, and with the grave opening before him, he felt the need of the consolations of religion. Christian faith cheered the sadness of his dying hours.98

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.
